Odin The Brave- A Tale Of Friendship And Survival Amid The Horrors Of A Wildfire

Northern California firefighters have spent the last week battling 14 separate infernos that claimed the lives of over 40 individuals. With 88 people still missing, the death toll is expected to rise. The fires, which began on October 8th, have charred over 220,000 acres of land and displaced thousands from their homes. Warming Northern climates and unusually high wind speeds of 50mph accelerated the Tubbs fire in Santa Rosa into a raging blaze that scorched mountains and destroyed nearby homes. Now, a little over a week since the fires began, the story of a heroic dog named Odin, who risked his life to protect a herd of goats, arises from the ashes of the blaze.

As the deadly flames of the Tubbs Fire tore through his property, Roland Tembo Hendel loaded his family, cats, and dogs into the car. At least, the dogs that would follow him. Odin, the family’s stubborn and fearless Great Pyrenees refused to abandon the goats that he was responsible for. Faced with the decision to leave behind his beloved dog or put his family in certain danger, Roland bid a sad farewell to Odin.

Roland described via Facebook that “even under the best of circumstances it is nearly impossible to separate Odin from the goats when he takes over the close watch from his sister Tessa after nightfall. I made a decision to leave him, and I doubt I could have made him come with us if I tried.”

Escaping with their lives and the contents of their pockets, Roland wrote on Facebook, “when we had outrun the fires I cried, sure that I had sentenced Odie to death, along with our precious family of bottle-raised goats.” But Odin—whose is named after the Norse God— proved to be the family’s “miracle”.

Preparing for the worst, Roland recounted via Facebook that as they returned to the “smoldering wasteland” and ruins of their home, they were miraculously greeted by a limping Odin and the eight goats that were left in his care. Odin survived the flames that took the life of one of Hendel’s neighbors — Lynne Powell — with burned fur, melted whiskers, and several deer who huddled around him for safety.

Send in the Goats

Meanwhile, suburban hillsides across Southern California have seen an increase in goats working to chomp away at overgrown brush and dry vegetation. As population growth pushes human habitation deeper into fire-vulnerable areas, risk of structural damage, injury, and even death are on the rise.

Traditional clearing methods like the prescribed burn— a fire deliberately set to clear out the threatening dry fuel— can too easily get out of hand. While some fire-prone terrain can be too rocky for mechanical equipment or expose expensive workers to uneven poison oak infested grounds, goats are almost always up for the job.

Since the story has gone viral,  Odin’s family has been showered with love and support and Odin himself enjoyed a large steak dinner. Other victims of the recent fires have not been so lucky.  Currently, wildfires continue to burn through Northern California, Portugal and Spain— claiming the lives of over 100 innocent victims unable to escape the flames.  As the climate continues to change, it is important to keep areas of dry grass manicured and educate yourselves on your local fire plans. If you hear of a wildfire burning in your area, please don’t wait—evacuate as soon as possible.


 

Cassini-The Wonder of Saturn  

At the California Science Center’s latest Lunch and Learn, Project Manager and Mars Specialist, Devin Waller, walked a group of around 25 financial contributors of the CSC from the Sun to Saturn.  The distance from Saturn (the sixth planet from the sun) and the actual sun spans approximately 891 million miles. Our stroll through a mock model of the solar system built by Science Center employees wasn’t quite as far as that. The walk itself could have been completed in no more than 5 minutes had Devin not gifted us with the engineering and scientific perspectives involved in replicating our universe. Models like the one pictured below help students and visitors of the California Science Center understand the intricacies of space.

We began at the Sun– a 4.5-billion-year old star that accounts for 99.86 percent of the mass in our solar system. Given its size, it is estimated that over one million Earths could fit inside of the sun! This giant ball of gas is composed of 70 percent hydrogen and 28 percent helium. As the two gases react, intense amounts of energy and heat are created. Without this energy,  there would be no life on Earth.

Next we arrived at the smallest and innermost planet, Mercury.  Mercury orbits the sun in just 88 days, making the shortest orbit of any planet. Each complete orbit around the sun represents one “year,” while a rotation on a planet’s axis represents one “day.”  Its temperature ranges from -297 on the side opposite the sun to + 800 degrees on the side facing the sun. Because Mercury is so close to the sun, it is hard to directly observe from Earth except during the hours of dawn or twilight.

The second planet we visited was Venus, a celestial body located 67 million miles from the Sun. Known as the rocky planet, Venus has the longest rotation of the solar system family and has a scorching temperature of 896 degrees.  It takes 224 Earth days for Venus to experience one “day.” Unlike most other planets in the Solar System, which rotate on their axes in a counter-clockwise direction, Venus rotates clockwise (this is called “retrograde” rotation).  Our home, Earth, is the third planet in line from the sun. One rotation on Earth takes 24 hours with a complete orbit around the sun lasting 365 days. Our planet’s average temperature is a balmy 61 degrees. In contrast, Mars is a rocky planet 141,700,000 miles from the sun that has a temperature of -81 degrees. With its thin atmosphere and lack of liquid water, winds drive the global conditions. NASA space projects have been studying Mars since the 1960s. According to NASA, the goal of the Mars Exploration Program has been to provide a continuous flow of scientific information and discovery through a carefully-selected series of robotic orbiters, landers and mobile laboratories interconnected by a high-bandwidth Mars/Earth communications network. Mercury, Venus, Earth, and Mars represent the terrestrial planets: inner planets closest to the Sun that are composed primarily of silicate rocks or metals.

As our tour moved on to the outer planets, we stopped at a replica of the gas giant known as Jupiter—the largest planet in our Solar System.  Like the Sun, Jupiter is composed of hydrogen and helium yet it is a cold planet (minus 234 degrees Fahrenheit). Its massive size and distance from the sun (483,500,000 miles) makes it so that it takes 11.86 years for Jupiter to complete an orbit. It has 67 known moons and like Saturn, Jupiter has rings.  Unlike the vivid, icy rings of Saturn, Jupiter’s rings are subtle, sandy structures.

Our final stops on the walking tour took us to Saturn, one of the most visually stunning celestial bodies in our Solar System, and a replica of the spacecraft Cassini, which spent over a decade studying Saturn. We had the great privilege of listening as Dr. Jo Pitesky, an engineer at the Jet Propulsion Laboratory who worked with Cassini from 2001 until 2017, provide details about Cassini and its twenty-year mission.  Cassini was the latest NASA spacecraft to explore Saturn, completing its journey on September 15th, 2017. Cassini launched in 1997 and arrived at Saturn seven years later. In that time, the spacecraft captured stunning photos of the planet’s weather systems (including the changing seasons in the Northern Hemisphere), magnificent rings, and it’s 62 moons while providing invaluable data on Saturn and its atmosphere.  Cassini viewed, listened, smelled, and even tasted Saturn’s moons– and what it learned about them is nothing short of remarkable. Probing Saturn’s icy moons, Cassini discovered that water is continually spewing out of jets around the southern pole of Saturn’s moon Enceladus. It also found liquid water on Saturn’s largest moon, Titan.   These extraordinary discoveries indicate that Enceladus and Titan have all of the ingredients necessary for life and make future space exploration all the more exciting. The “Grand Finale Orbits” that carried Cassini to its end helped solve longtime mysteries such as the planet’s rate of rotation, the length of a day on Saturn, and the mass of its stunning rings. Dr. Pitesky made her commitment to the project transparent, explaining that she could spend weeks describing Cassini accomplishments.

The start of Cassini’s final voyage began on September 12th, 2017.  Cassini continued transmitting messages as long as possible until the force of Saturn’s atmosphere overpowered the spacecraft thrusters and Cassini could no longer make contact with Earth. At 3:31 am (PDT) on September 15th, 2017, Cassini’s final signal was received. As Dr. Jo Pitesky narrated the extraordinary life of Cassini and its final descent to Saturn, it was hard to find a dry eye in the room.  Showing us photos of the thousands of men and women involved in the Cassini mission– to provide information and educate the world– she likened its journey to the following quote.

“Though here at journey’s end I lie
in darkness buried deep,
beyond all towers strong and high,
beyond all mountains steep,
above all shadows rides the Sun
and Stars for ever dwell:
I will not say the Day is done,
nor bid the Stars farewell.

Urban Coyote Conflicts

Growing up in the suburbs, my friends and I spent many weekend nights powerwalking through our neighborhoods, deep in conversation. It was an excellent way to process through our angst-laden teenage years while maintaining our physique. Though a few street lamps could be seen scattered about the city’s larger streets, the blackness of night was for the most part unfettered by light. In my youth, I appreciated this obscurity and reveled in the fact that most nights we had the streets to ourselves. One night, as we walked towards an intersection lit only by the red hand of the cross walk sign, we heard the sound of movement in the nearby leaves. Realizing that we were no longer alone, I turned my head in the direction of the noise and saw two yellow eyes peering back at me. My first thought was to run. My second was to scream. Ultimately, fear kept me frozen in place and silent as a mouse. The eyes grew larger and as the body they were attached to came closer, I found myself within feet of a large coyote.  I watched in amazement as the coyote made its way through the crosswalk, keeping within the lines.

The Urban Coyote

Coyotes (Canis latrans) are smart. In response to shrinking wild spaces, these cunning creatures have migrated from their origins in the American southwest to nearly every corner of Northern and Central America (save for Hawaii). This forced migration has encouraged new survival instincts in coyotes obliged to thrive in pastoral and suburban regions as well as densely populated urban landscapes.  A coyote’s versatility extends to its diet, which changes based on what’s available in its environment. Typically, their diet consists of rabbits, squirrels, mice, rats, insects, reptiles and wild berries. In the wild, coyotes generally keep their distance from humans. Yet, as natural predators and barriers of habitat shrink, the interface between wild and domestic begins to expand. Over the past two decades, America has seen a swelling of inner-city coyote populations. In that time, generations of coyotes who have never known undeveloped spaces have been born into metropolitan areas that lack green landscape. These native city-slickers have become adept at surviving in urban settings- foraging through dumpsters and compost bins, navigating crosswalks, and consuming small domestic pets. Weighing anywhere from 15-50 pounds, their smaller frames allow them an agility that makes hopping an eight foot fence in the suburbs nearly effortless.

A Canine Confrontation

Every year, local police and wildlife organizations receive thousands of reports of coyotes disrupting the domestic sphere. For the most part, human encounters with a singular coyote or a small pack have not proven consistently dangerous. However, as urban coyote populations rise, reports of attacks on individuals and pets have amplified. In 2009, 19 year-old Taylor Mitchell died of blood loss after coyotes bit her while she was walking on a trail in Eastern Canada. Though not an urban attack, sensational media often draw from the experience with Mitchell to illuminate the perils of human-coyote interaction. Experts indicate that the keys to maintaining safety are to keep coyotes from getting accustomed to humans and to limit interaction. Hazing, the practice of scaring off coyotes with deterrents- shouting, clapping, blowing air horns, or spraying with water- is considered the basis of coyote management plans which seek to discourage coyotes from becoming too relaxed in their urban surroundings.  Pupping season lasts from August until January. During these months, protective mothers are more likely to act in defense of their dens. If you encounter a coyote at this time, the best thing to do is to slowly and calmly walk away without turning your back on the coyote. Stay tall and assertive as you leave the area, even if it means walking backwards.

This Way Forward

The relationship between human and coyote is extremely complex and warrants a deeper look. It is significant to note that human development continues to displace wildlife from their homes.  While property on the foothills is desirable, one should prepare themselves to encounter emigrant wildlife. The Urban Coyote Initiative is a group of photojournalists who aim to shed light on the lives and behaviors of coyotes living in close proximity to humans.  Organizations like these remove the mystery of urban coyote behavior and lay the foundation for a more harmonious inhabiting of shared space. You can see some of their work here.

Can Animals Predict Earthquakes?

For the second time in two weeks, an earthquake has struck Mexico, leveling sky rises, splitting freeways, and killing over 270 people.  The 7.1-magnitude quake that occurred Tuesday afternoon has overwhelmed residents and officials of Mexico City.  Located in a region known as the Pacific Ring of Fire, a 25,000-mile U-shaped ring of Pacific coastline that stretches from the Indian-Australian Plate to the South-American Plate, Mexico City is an area that is notoriously at risk for major earthquakes.  Linked to 80 percent of global quakes, the Pacific Ring is considered one of the most seismically active areas on the planet.

What Causes Earthquakes and Can They Be Predicted?

An earthquake occurs when massive blocks of the earth’s crust known as tectonic plates, suddenly move past each other, releasing built up pressure and energy in the form of seismic waves.  These seismic waves are responsible for making the ground shake.  Currently, seismologists have not figured out a way to predict earthquake far enough in advance to avoid the mass casualties that accompany colossal quakes. Though extensive research and scientific support has yet to approve these theories, many suggest that animals have the capacity to foreshadow earthquakes before they occur.

Animal Instinct

Since the time of ancient Greece, some historians have maintained the belief that animals have the ability to predict the arrival of earthquakes. After a devastating earthquake decimated the Greek city of Heline in 373 B.C, townsfolk reported that snakes, rats, centipedes and weasels were seen fleeing the city in the days leading up to the quake.

Similarly, Chinese officials ordered the evacuation of Haicheng, a city with over one million residents, just days before a 7.3-magnitude quake in the winter of 1975. This order came after a large number of snakes in the area interrupted their hibernation and emerged from their burrows. Normally this surfacing would not be a cause for concern, but winters in Haicheng can be brutally cold and temperatures at this time were below freezing levels. Snakes are cold-blooded reptiles who must maintain a warmer body temperature to survive. During winter months, they tunnel themselves deep within the ground and remain there until spring. As witnesses in Haicheng reported the snakes leaving their burrows and exposing themselves to the frigid cold, officials became alarmed and evacuations began.  When the earthquake arrived two days later, a small portion of the population who failed to evacuate were hurt or killed while close to 150,000 evacuees were spared.

Arguments from those who believe that animals have the ability to predict natural disasters rely on the understanding that earthquakes generate electrical fields and magnetic fluctuations.  Since many animals have the ability to hear infrasonic sounds like the low rumbling of an onrushing earthquake, it is possible that they can sense a quake before we can. Additionally, changes in the mineral and chemical composition of  groundwater have been measured before the onset of a quake. Historically, instances of entire amphibian populations (frogs and toads) abandoning their swampy homes before an earthquake have been reported. In 2010, the Journal of Zoology published a study in which a colony of toads deserted their mating site three days before an earthquake struck L’Aquila in Italy. The toads did not return back to their homes unit the last aftershock hit 10 days later. Studying a pre-quake mass exodus like the one in Italy could help scientists dechipher the connection between animal instinct and natural disaster. However, the US geological survey says there is just not enough evidence to conclusively determine that animals are accurate predictors of a quake well enough in advance.

A New Way Forward

Seismologist Joseph L. Kirschvink suggests that an animal’s instinctual fight or flight response may provide a sort of early warning system for seismic events.  Building on his theory, the German-Russian lead project, Icarus (International Cooperation for Animal Research Using Space) uses a satellite-based monitoring system to track the response of mass migrations of birds as they pass through the epicenter of an earthquake. Icarus researchers are counting on migrating birds to cross the path of at least one of the 100 large scale earthquakes that happen each year. If the birds sense the epicenter and re-route their traditional migratory paths away from it, positive evidence that animals have the instinctual ability to foretell the coming of an earthquake can be examined.

After the Hurricane- Wildlife Watch

All week reports from a water-logged Florida, Texas, and the Carribean have been pouring in. Torrential downpours and massive flooding have devastated communities as Hurricanes Harvey and Irma passed through.  Many in the world watched in shock as the sea stormed the barriers, rushing through the streets of Miami to climb the lower levels of high-rises and tearing a path through the Carribean. Without discrimination, the maelstrom claimed humans, homes, and history for its own, leaving piles of debris as the only reminder of what formerly stood. Emergency services were called in to rescue evacuated families and their pets as their homes became victims of the flood.

Accounts of the next storm system, Tropical Storm Jose, have made their way to headlines  and the East Coast of the US is bracing itself for its projected touchdown later this week.

It has been nearly three weeks since Harvey flooded 28,000 square miles of Texas, and almost a week since the Irma struck the Caribbean and Florida. As the flood waters recede, over 200 million cubic yards of debris have been revealed in Texas alone. The extent of damage from Irma, which is still rolling through the country as a smaller tropical storm, has yet to be determined. Today the death toll for Harvey and Irma stands somewhere around 125 people, and hundreds of billions of dollars in property damage has been reported thus far.

Unaccounted for in the post-storm figures are the wildlife populations that could not relocate to higher ground when flood waters were rising. Over the past three weeks, the World Animal Protection Charity has sent emergency teams to Texas and Florida to rescue and care for wildlife. Teams of professional rescuers and volunteers have spent countless hours locating and rehabilitating injured animals following the storms. While clean up efforts in affected areas are well underway, it will take months for teams of experts to understand the full scale impact on wildlife.

Hurricane Irma Leaves Manatees Stranded 

Last Sunday, Hurricane Irma was still 100 miles away from Tampa when it sucked the water out of shallow Sarasota Bay, an ideal habitat for manatees. The Florida Wildlife Commission had received several calls about stranded manatees, also known as sea cows,  when a passerby and two sheriffs noticed two manatees beached in the newly-dried bay. In a heroic effort to save the protected marine animals, the sheriffs rolled the 1000 pound manatees onto a sheet and dragged them over 100 yards to the sea.

When a Tree Falls

Trees provide a habitat for already vulnerable species. During a hurricane, high winds can uproot trees and displace the animal tenants living within. Many bird species that use trees as a convenient shelter have the ability to migrate to drier areas, and often times they are aware of a storm before it arrives. Ornithologists describe that most birds can sense even the slightest changes in barometric pressure, which makes them a kind of a living barometer. Once the message has been received that barometric pressure is low, they take flight and head for dryer areas. However, powerful winds can blow the migrating birds off of their course. At best, these birds can reroute themselves back to their homes once the storms have ended, but often they are injured or weakened and have been deprived of food so many do not survive. Both Hurricane Harvey and Hurricane Irma intersected the beginning of the annual fall migration, which according to ornithologists, guarantees some level of bird displacement.

In certain cases, birds do not have the opportunity to migrate away from the storm. Take the red-cockaded woodpeckers in South Carolina’s Marion National Forest for an example.  When Hurricane Hugo hit the area in September 1989, approximately 60 percent of the 500 groups of birds perished when 87 percent of the trees containing cavities where they lived were destroyed. Thanks to extensive rehabilitation efforts, populations have been returned to their numbers in the years since Hugo slammed the state.

How Are Hurricanes Formed? 

As deep layers of warm ocean waters stoke an emerging thunderstorm into a mature state, a hurricane is born. Sea surface temperature is one of five factors that influence the formation of tropical cyclones, defined as rapidly rotating storm systems categorized by low-pressure centers, the presence of thunderstorms, heavy rain, strong winds, and low-level atmospheric circulation. Specifically, a hurricane is a tropical cyclone occurring in the Atlantic and northeastern Pacific Oceans.   The warm water temperatures of the Gulf of Mexico make it a notorious landing point for hurricanes. According to oceanographers, temperatures of the oceans in the Gulf of Mexico are the highest that they have ever been in recorded history and these spikes in temperature can account for some of the increase in hurricane potency. Warm water is only one of the ingredients needed to produce a full-fledged hurricane. Humidity, wind shear, and a generally unstable atmosphere are also required to help craft the “perfect storm.”

Ironically, the “perfect storm” is just that for certain plants and animals that survive its force. While hurricanes can be devastating to many wild animal populations, other animals manage to survive and thrive during and after the event. Orchids, gopher frogs, raccoons, and brown bears are among the animals that are generally positively impacted by a hurricane (so long as they survive).  Orchids use intense winds to spread their seeds, frogs breed in heavy rainfall,  raccoons scavenge for food, and bears use the fallen trees as shelter.

Sea turtles, marine life, small ground animals, livestock, and domestic pets can all fall victim to the destruction of habitats and the scarcity of food sources that are associated with hurricanes.

As another Tropical Storm Jose matures in the distance, rescue efforts are still underway for the countless animal victims of the latest natural disasters. While it’s too early to fully estimate impacts of Hurricane Harvey or Hurricane Irma on wildlife, it is important to recognize that recovery efforts will need to extend beyond far beyond human development. Locals in affected areas have begun reporting injured animals to their local officials and people around the world are making donations to support habitat conservation and protection efforts. You can help provide relief for human and wildlife foundations by donating to organizations that you trust.  For more information on individual organizations, click here.

Until next week, remember to appreciate your life, give to those in need,  and keep exploring your world.

Ecosystems: Kelp Forest Part 2

Last week’s adventures took us through the California Science Center Exhibit- Ecosystems. Continue the Journey with us this week as we learn about life inside wild Kelp forests. 


In the wild, the bottom level of the ocean is known as the benthic zone. All bodies of water have a benthic zone where creatures like snails, sea stars, oysters lobsters, and other crustacean reside. Organisms living in the benthic zone are called benthos and play a fundamental role in ecosystem management. Since light does not often penetrate the benthic zone, benthos feed on the dead and decaying matter found on the ocean floor, benthic algae, and young kelp.  Areas outside of the ocean’s benthic zone are either a part of the supratidal and subtidal zones (the areas found on the coastline that are impacted by high and low tide), the neritic zone (the shallow part of the ocean that extends to up to 200 meters in depth) or the pelagic zone (the area between the benthic and neritic zones). Most of the sea life that lives away from land or outside of the benthic zone is found in the pelagic zone.

Often miscategorized as a plant, kelp is actually a species of brown algae (Macrocystis pyrifera), that grows in dense groupings, similar to the way a wooded forest grows on land.  The strands of kelp found in the controlled environment of the California Science Center grow to an impressive height, but are significantly smaller than the wild kelp forests, which can reach up to 175 feet in length. Kelp is prolific in growth and in ideal circumstances, can gain anywhere from 10 and 12 inches in a single day.

Much like a buoy, the gas-filled bladders located at the base of the kelp leaf are responsible for holding up the kelp as it spreads from the bottom of the ocean floor to the surface of the water. Once the kelp has reached the surface, it forms a dense canopy that provides shelter and food for thousands of invertebrates, fish, and marine mammal species.

Kelp forests cross the benthic, pelagic, and neritic zones, and are home to a diverse group of marine life. In fact, the kelp forests found off of the California coast can accommodate over 1,000 species in a single forest, and are among the most diverse ecosystems found on earth!  Many organisms use the dense blades of the kelp to hide from predators and rear their young. Seals, sea lions, whales, sea otters, fish, gulls, and other sea birds are some of the many animals found in the canopy’s armor.  Rich in varied food sources, the kelp forest ecosystem offers a perfect example of the hierarchical nature of the food web. As numerous species thrive in the shelter of the kelp, predators have greater access to food.  For example, kelp is eaten by tubeworms who are then gobbled up by birds and fish. Fish are the principal food source for baleen whales and sea lions.  Sea lions become the prey of the ocean’s top carnivores including sharks and killer whales (pictured below).

Like the tubeworm and other small invertebrates, the primary food source of the sea urchin is kelp.  However, urchins present a huge problem in kelp forest management because of the alarming rate in which they consume the algae matter. Sea otters and spiny lobsters are the natural predator of the sea urchin, and as such their role in the ecosystem is vital.  When an urchin population balloons, kelp forests run the risk of depletion and the animals that use the canopy as shelter become vulnerable to predation. In order to manage urchin populations and conserve the delicate ecosystem, California Science Center staff and volunteer divers have joined local forces to remove over 100,000 sea urchins from the Palos Verde Peninsula. Considered a delicacy in fine dining cultures around the world, these sea urchins are often captured and sold to the restaurant industry.

Currently, the California Science center offers visitors the opportunity to pet urchins, sea slugs, eninimes, and other invertebrates. During our visit, I felt like a child who had returned to the coastal tide pools I loved so much as a kid. Using two gentle fingers (as advised), I stroked the back sides of sea slugs, explored the spines of urchins, and shook tentacles with an anemone.

Throughout history, humans have devised numerous uses for kelp.  During World War I, kelp was harvested to make potash, a manufactured salt that contains potassium in water soluble form. During the war, potash was a major component of fertilizer and gunpowder. Following a German embargo on potash in 1914, American scientists and businessmen turned to the sea to extract potash from California’s giant kelp. By the 1930s, food and pharmaceutical corporations began extracting algin, a thickening, stabilizing, and gelling agent from kelp. Currently, algin is a popular additive used in a number of processed foods.

Visiting the synthetic kelp forest at the California Science center was truly a treat. Now, it is time to put on my fins and explore the wild forests off of the California Coast. I know that not everyone will have the opportunity to dive into the ocean ecosystems, but no matter where you live, some form of wilderness is available to you. Remember to get outside, ask questions, search for answers, and explore your world!

Inside the Ecosystems- Kelp Forests Part 1

The Ecosystems exhibit at the California Science Center is a permanent fixture of their wide-ranging offerings. Visitors of the museum can explore eight diverse environments and ecosystems alternating between the “Extreme Zone” and “Rot Room” to the “Forest”, “Island,” and “River” zones. On Saturday August 26th, 2017 the Havasi Wilderness Foundation was given a private tour of the Kelp Forest exhibition, which has been open to the public since 2010. Dr. William Johns, Director of Life Support Systems at the California Science Center, acted as our personal guide for the day.


Beneath the floors of the California Science Center a deep humming emanates from a complex electrical grid that powers much of the facility. Thick pipes carrying water to and from the 188,000-gallon salt water tank housing the Kelp Forest Ecosystems exhibit line the walls and ceiling of the ground level. The area is cooler, wetter, and louder than most other parts of the museum, but the constant purring of water rushing through the pipelines had a soothing effect on me.

The kelp forest at the California Science Center is home to hundreds of marine animals across dozens of species, ranging in size from a microscopic crustacean to a five-hundred-pound giant sea bass. To feed the animals, on-staff divers and volunteer divers are employed to enter the tanks. Some fish require spot feeding methods (picture a scuba diver using tongs to feed chopped pieces of fish or crustacean to other carnivorous fish) to ensure that they receive the proper nutrients. The marine life in the kelp forest ecosystem exhibit eat and excrete several times a day, generating a sizeable amount of waste. Engineers and Technologists at the California Science Center work to develop systems that manage all of the waste.

Just around the corner from the bottom floor elevator, sits an intricate filtration system comprised of giant cylinders measuring eight feet round and sixteen feet long. Dr. Johns explained that these tanks are packed with pressed gravel to filter out large and small waste matter from the water so that it can be recycled back into the kelp forest ecosystem. Unlike the Long Beach and Monterey Bay aquariums which discharge their marine exhibit waste back into the ocean, the California Science Center relies on sophisticated equipment to recycle and treat their wastewater. After the wastewater is filtered from the aquatic tanks, it starts a complex process wherein the concentrated salt byproduct from filtered saltwater must be flushed with fresh water to avoid an over-concentration of salts, maintaining the delicate salt to water ratio in treatment facilities.

Fifteen minutes into the tour, the elevator dings and the doors slide open, inviting us to move on. We exit and begin our exploration of the dark rooms that provide an ideal viewing space for the saltwater tanks that make up the kelp forest installation. The exhibit itself is two stories tall. At the bottom level, visitors discover the ecosystem from the perspective of the marine life inside of the kelp forest.  As we approach the glass, I see two giant sea bass weaving between the leopard sharks and bright-orange garibaldi that surround them. In the corner of the tank, a moray eel pops its head out from behind a rock and floats, one eye locked warily on visitors to its home.  Three large splashes coming from the top of the exhibit indicate that it is feeding time. The divers, who are extensively trained to distinguish between different species of fish, pull out their tongs, grab a chunk of fish meat, and get to work. When we meet with a shivering volunteer diver later that day, he explains that the challenges of spending an hour in 56-degree water include being extremely cold. “However”, he says, “I love coming to the California Science Center to learn more about the marine life that we feed, and cold or not– I would gladly give up a few of my weekends to keep doing it.”

Total Eclipse– Or a Part

Predictions of animals behaving strangely during the solar eclipse have made it into the news for weeks prior to today’s event. In preparation for the eclipse, I read about spiders deconstructing their webs, chickens heading home to roost, bees returning to their hives, and goats gathering in groups during the diminished sunlight that is brought about by an eclipse.  Southern California news sources reported that the best time to view the “Great American Eclipse” was 10:15 AM Pacific Standard time. In an attempt to witness some of the odd animal behavior,  I ventured out to the Abundant Table Farm Stand in Camarillo, California during the reported height of the eclipse. Dawning a pair of paper glasses used to filter the light from the sun, I set my eyes to the sky and marveled in wonder and amazement as the moon passed in front of the sun. As the enchantment that comes from witnessing the magic of our solar system passed, I traveled towards the animal enclosure. The goats at the Abundant Table Farm were eager to munch on the weeds and carrots tops that I fed them, and though hungrier than normal, their behavior did not seem unusual in any way. The same holds true for the chicken, pigs, and sheep that I traditionally visit when there.

Since California is out of the line of vision for the total eclipse, it is likely that the animals barely noticed the dimming of sunlight. Though impossible to be sure what was happening internally, I can report that from my viewpoint, the animal’s routine did appear to be disrupted by the partial eclipse. While I am slightly disappointed to have missed the absolute eclipse,  I have truly enjoyed the influx of comical photos showing dogs enjoying the eclipse (see below).

The US has experienced several partial eclipses in recent history. However,  today’s eclipse marks the first time in nearly a century that a total eclipse has been visible from both ends of our country (the last total eclipse for the North American continent was recorded in 1918). According to Nasa.gov, the path where the moon completely covered the sun stretched from Salem, Oregon to Charleston, South Carolina. Observers like myself, who were located outside of this path, were still treated to a partial obscuration of the sun. Those lucky enough to be inside the path of the total eclipse experienced two full minutes of daytime darkness.

Though the moon orbits the Earth monthly, a precise alignment is necessary for an eclipse to transpire. Nasa.gov reports that an eclipse occurs only when the sun, moon, and Earth meet at the “line of nodes,” the imaginary line that represents the intersection of the orbital planes of the moon and Earth. A total solar eclipse, where the sun is entirely covered by the moon, occurs when the moon passes directly between the sun and the Earth. During this time, spectators in the line of this phenomenon can see the brighter stars and planets briefly emerge in the sky.

Regardless of your position in the world, witnessing an eclipse in any way is a truly momentous event!  The next solar eclipse should pass through South America in July of 2019, and in the early spring of 2024. Anyone in the US who missed today’s eclipse will have another opportunity to experience this wonder.


Looking directly at the sun is incredibly damaging to the sensitive tissues and complex systems of your eyes. Please take caution when viewing an eclipse and only do so through specialized lenses. NEVER look into the sun.

“Thar She Blows”- a Whale’s Tale

The waters surrounding Channel Islands National Park are abounding with wildlife.  A recent whale watching expedition gave the Havasi Wilderness Foundation the opportunity to interact with some of the 27 species of whales from the family cetacean who call the Channel Islands their home.


Somewhere around 26 miles from the Santa Barbara coastline, calls of “thar she blows”, a popular expression among whalers that is used to sound out the appearance of a nearby whale, could be heard from a choir of young children abroad the Condor Express. Spinning around to secure a spot on the starboard side (a nautical term that signifies the right side of the boat), I could see the short geyser of water that jetted from a whale’s spout.  As we readied our cameras, three humpback whales took turns surfacing for air. The sea around the whales was alive with movement. While dolphins and sea lions could be seen jumping enthusiastically out of the water nearby, the whales themselves were not as easy to see. Their large backsides surfaced long enough for a spout of water to shoot into the air before they bobbed beneath the sea again.

Cetaceans are a diverse grouping of carnivorous aquatic mammals that are widely distributed through the Northern and Southern Hemispheres.  The family includes dolphins, porpoises, beluga, and whales, and is separated into two groups: toothed and baleen whales.  As their name suggests, toothed whales (or odontocetes) have teeth which they use to trap their food. Examples of toothed whales include the great white whale (most famously depicted in Herman Melville’s 1981 biopic Moby Dick), the sperm whale, and dolphins. Dolphins can be found swimming deep in the channel as well as in areas around surfers close to the California shoreline. They are some of the friendlier toothed whales and are renowned for their intelligence, curiosity, and complex communication style. Their sophisticated communication capabilities have been described to sound a lot like a whistle which allows them to exchange information with other members of their pod.

The baleen whale (or mysticetes) derives its name from the thick stringy layers of baleen that attach to the whale’s gum line. Baleen is made of keratin (the same substance that human fingernails and hair are made of). Unlike toothed whales, who use sonar to track down food and capture prey with their teeth, the baleen whale vacuums gallons of water from the sea and relies on the straw-like baleen to filter fish and krill from the mouthfuls of water that they ingest.  Austin MacRae, a naturalist from the Channel Islands Naturalist Corps and our guide for the day, explained to us that in one gulp, a large baleen whale can swallow enough water to fill a medium-sized swimming pool! As I absorbed this information, I wondered aloud, how do whales carry and then expel such great amounts of water?  Austin provided the answer: ventral pleats.  Similar to a pelican’s pouch, the ventral pleats that line the abdomen of baleen whales, expand and contract like giant accordions. In one movement, they help push hundreds of gallons of water over the tongue and out of the whale’s mouth. During the expulsion of water, hundreds of small fish and plankton become trapped inside of the baleen where a whale can swallow them whole.

The boat rocked violently in a moody sea as we continued watching the three humpback whales. Known for their particularly large pectoral fins, humpbacks often use the technique of pectoral fin slapping (commonly referred to as “pec slapping”) to attract the attention of the opposite sex during mating season. When slapped against the ocean’s surface, their fins produce a spectacle of booming sounds and massive waves. Though we did not witness any pectoral slapping on our trip, we were amazed to see one of the more high-spirited humpbacks lift its tail high out of the water and smack the surface of the sea. As its tail plunged back into the dark ocean, Austin explained to us that like the human fingerprint, the humpback’s tail fin (called a fluke) is unique to each whale. Currently, researchers use high definition photography to capture images of flukes and add them to a database managed by NOAA (National Oceanic and Atmospheric Administration). These images help identify individual humpbacks, monitor their health, and track their whereabouts. This tracking system is significant because, according to NOAA, Humpback whales live in all major oceans from the equator to sub-polar latitudes and occasionally shipping channels, fisheries, and aquaculture may demolish humpback whale congregation areas.

Weighing in at a whopping 150 tons, the blue whale holds the record of the largest mammal on the planet. To sustain such a massive creature, 9000 pounds (4.5 tons) of fish and krill must be consumed each day.  Though we did not encounter any blue whales on our expedition, they can be found feeding in the waters off of the Channel Islands during the summertime before heading to the warmer waters of Mexico to have their babies. Austin shared his thoughts about blue whales with me, explaining:

“I always like to talk about blue whales because they are the biggest and heaviest of animal ever to live on the planet! Bigger than any dinosaur even! The heart of a blue whale is the size of a Volkswagen and so, hypothetically, a child could crawl through its arteries. The tongue of a blue whale is as heavy as a bull elephant and their lungs are as big as a school bus. Essentially, they are gargantuan! They weigh 200+ tons and can reach sizes of up to 110 feet long in the Antarctic Ocean.”

Waters off of the coast of California vary drastically from those in the Arctic Circle. A cold northern current and a warm southern current collide in the waters off of the Southern California coast and create large nutrient pockets. These pockets of dense nourishment act as ideal feeding grounds for whales, dolphins, sea lions, and other marine mammals who use the summer months to build up fat stores (blubber) that they will live off of during the winter.  Like human mammals, whales must maintain a body temperature of 99 ° Fahrenheit (37 ° Celsius). In order to preserve this temperature, they migrate from cooler waters in the summertime to warmer waters in the wintertime.

As humans, we rely on our autonomic nervous system to regulate our breath. This allows us to breathe involuntarily, without ever having to think about it. Unlike human beings, humpback whales are conscious breathers, which means they have to remember to breathe at all times- even when they are asleep. To ensure that they remember to surface for air, cetaceans conserve half of their brain function while sleeping. Researchers studying dolphin and whale populations in captivity have noted that dolphins seem to shut down half of their brain and sleep with one eye open (the eye on the opposite side of the resting brain) for a period of around two hours. After two hours, the opposite side of the brain shuts down and the corresponding eye will close.  It is mind-boggling to think of the evolutionary trait that encourages continual consciousness among cetaceans.

Like dolphins, humans have been historically curious about the world that surrounds them. With less than ten percent of the world’s oceans having been explored,  there are still entire ecosystems that remain a mystery to us.  Rather than succumb to a life of uncertainty, it is important to feed your curiosity, get outside, and explore your world!

Until next week,

Lola


Interested in whale watching? The Condor Express (Click link to view) is an excellent option for a whale expedition. The leave from the Santa Barbara Harbor and guarantee that you will see whales. If for some reason the captain cannot find any whales during your day trip,  then you can return without a fee to go on an expedition until you do see one. Remember that when you’re exploring, you should take plenty of sun screen, a hat that shades, long-sleeved clothing, and (if you tend to get as queasy as I do) find some Dramamine and bring along a carbonated beverage as this helps sensitive stomachs. Take it from me, you should never go out on a boat without having something in your stomach.  

Anchors up and full steam ahead!

Panama Adventures Part 2: Going Bananas!

From Europe and Asia to the American and African continents, consumers are united by their love of bananas. On a global scale, bananas are the world’s most consumed fruit and the fifth-most traded agricultural product. What’s not to love? Bananas are portable, versatile, and in developing nations they provide much of the nutrition needed to sustain life.  In my home, bananas are a staple. My partner’s mother practices a morning ritual that includes splitting a banana in half, consuming her portion and sharing half with our banana-loving dog, Margot. The mere mention of Margot’s favorite word, “banana”, causes her ears to stand at full attention as she waits for someone to throw a slice or two in her direction.

Recently, I had the pleasure of touring the La Loma cacao farm on Panama’s Isla Bastiemientos. Going in, I expected to learn primarily about the chocolate-making process but was surprised to walk away with a deeper understanding of contemporary bananas and their significance in the formation of the Panamanian cacao trade.

It is important to note that wild bananas look nothing like the bananas found in grocery stores today. With thick skins, gooey flesh, and bodies filled with seeds, a wild banana seems anything but appetizing when compared to its breeded counterpart. Though seeded bananas make for easy reproduction in nature, banana farmers discovered that consumers prefer bananas without seeds, and began using the genetic material in plantains to breed a seedless banana variety. On contemporary plantations, bananas propagate (grow) vegetatively and are sterile clones of the previous generation. Like succulents and other vegetative plants, next generation banana growth extends from existing plants through shoots called suckers. As soon as the fruit is harvested from the primary growth, the plant must be pruned back so that the new growth can collect the nutrients and water stored inside of the base of the plant. People often use the word “tree” to describe the structure that bananas grow on, but the plant is actually an herb that produces berry-like fruit– the banana!

Prior to the 1950’s, much of the agricultural land in Panama was reserved for growing America’s favorite tropical fruit. Humidity, high temperatures, and a cooling off-shore breeze provide an ideal growing environment for bananas, which thrive in such settings. By 1940, bananas were one of Latin America’s main exports and large-scale banana operations supported the Panamanian islands collectively known as Bocas Del Toro, where I toured the cacao farm. Though the majority of land today is under cacao production, a history rooted in banana growth can be seen peaking out from beneath a canopy of cacao leaves.

In the first half of the 20th century, the Gros Michel variety was the primary banana available on the market. Smaller and sweeter than today’s Cavedish bananas, Gros Michel bananas were the victims of a deadly strain of fungal pathogen known as Fusarium Wilt, or more commonly as the Panama disease. The disease, which produces a fungus that affects the vascular system of host plants, wiped out nearly all banana plantations in Central and South America. Other vulnerable crops include tomatoes, legumes, tobacco, cucumbers, and sweet potatoes. When fusarium wilt infects crops that reproduce by seed, the disease is easier to manage. However, when it attacks a crop that is a clone of its parent plant, an entire generation can be destroyed and suffer extinction. As such, Panama’s Gros Michel plantations were barren by the 1960’s. For an economy dependent on the export of its bananas, the Panama disease was a devastating blow. New generations of resistant fruit were developed to replace the diseased Gros Michel crops. However, the still seedless Cavedish banana suffer from the same problem– lack of genetic diversity. Presently, a new strain of fusarium wilt is plaguing banana plantations across the globe and threatening the banana industry once again. As humans use selective breeding to produce more favorable qualities such as large size and ease of growth, offspring have less genetic diversity and thus an increased susceptibility to natural selection.

Following the first wave of fusarium wilt, the Panamanian government offered banana growers the opportunity to keep their land in production by cultivating a new crop. Hundreds of free cacao plants were offered to any grower willing to farm them. In the 60’s, Hershey’s Chocolate was king and global tastes favored milk chocolate over the dark, bitter treat that pure cacao helps produce. As artisanal chocolates increase in popularity, international cacao production is in high demand and the Islands of Bocas Del Toro are back on the map!
