Birch Aquarium at Scripps is taking gradual steps toward sustainable business practices. Our most recent success involved upgrading 150 exhibit lights to energy-efficient light-emitting diode (LED) bulbs. Find out why this facility improvement means so much to us.
Exhibit carpenter Kevin Stephens has been darting back and forth between Birch Aquarium’s exhibit workshop and his desk for the past five minutes. Each time Kevin ducks into his office, he reemerges cradling an armful of empty lightbulb boxes and a couple of bulbs he hasn’t shown me yet. We begin to adorn an acrylic-topped workbench with flood-lights and spotlights, lining the bulbs up to compare new and old designs.
A selection of current and past lightbulbs used by Birch Aquarium. The newest LED bulb (far left) weighs less and is more energy efficient than the halogen bulb (far right). The three bulbs in the center are different generation models of LEDs (newer, left; older, right).
Kevin steps back into his office and rummages through a cardboard box for one last bulb. “Now, this is an early-style LED. Imagine trying to support twenty of those on one lighting track,” he postulates, handing me the weighty 1.6 pound bulb. “We couldn’t use LEDs initially. They were too heavy and didn’t produce enough light for our displays.”
Upgrading to LED lighting has been a gradual process for Birch Aquarium. Over the past five years, the aquarium has switched to increasingly energy-efficient lightbulbs. Energy-sucking 90-watt incandescent bulbs were first replaced with 75-watt halogens, then 23-watt compact fluorescents (CFLs). However, Birch Aquarium exhibit developers were disappointed by the gray light that the CFLs produced and hoped that LED technology would soon catch up with their artistic ambitions. They didn’t have to wait long. “We got excited when we learned that UC San Diego had acquired some money that could help improve our exhibits,” Kevin says. He hands me an example of one type of LED bulb which now illuminates the aquarium’s exhibit galleries.
Exhibit carpenter Kevin Stephens holds up one of the LED light bulbs now in Birch Aquarium exhibit galleries.
Don’t let the stylish look of this LED fool you—it is a remarkable advance in energy-efficiency.
By rotating a powerband ring, users can select from three power level settings (10, 14, or 16 watts) to choose the amount of light that suits their needs. Weighing less than a pound, this LED model is used in 100 of Birch Aquarium’s 150 light fixtures. The remaining 50 fixtures in the Hall of Fishes use an LED model that consumes even less energy—a mere five watts! These LEDs are cutting Birch Aquarium’s energy use by 35,000 kilowatt-hours per year. That’s enough electrical energy to power 4.2 homes for a year!
Painting exhibit spaces with light
Interior lighting creates an aesthetic experience for Birch Aquarium visitors. Lighting effects are used to create a mood, soften transitions between displays, or highlight special objects. Birch Aquarium exhibit developers take pride that new LED lights are providing an enhanced experience for guests. Each LED bulb has three donut-shaped diodes, which disperse light where our staff needs it. “I am impressed with the improved optics,” Kevin observes. “Each diode is like a prism.” The LEDs produce bright white tones, which better match outdoor light conditions. This brings out subtleties in exhibit photographs and gives other graphics a crisper look.

The latest model of LED bulb has an ingenious feature: pen point-sized holes in the lens (see photo below). These holes draw air through the bulb and keep it cool, allowing engineers to develop lighter, thinner heat-dissipating ribs on the back of the bulb. Not only do these new LEDs reduce weight on ceiling light tracks, but they keep exhibit spaces cooler, thereby preventing the air conditioning system from being overtaxed. “When we needed to replace the halogens, it was like playing hot potato. We needed a rag to handle them. These new LEDs are easier on the user.”
The holes in the lens of this LED lightbulb help to draw air through it and keep it cool. Also, did you notice the three donut-shaped diodes?
The curved ribs on the back of this LED lightbulb help to dissipate heat.
Saving time and money
Using LEDs is not just energy smart, it’s business smart. More like a no-brainer. Kevin sits down at his desk and thumbs through a stack of manila file folders to find a copy of Birch Aquarium’s recent energy-use assessment. He hands me a sheet of paper with key information highlighted in black boxes at the bottom. I begin reading: Average electrical savings: 77.5%. Energy savings per year: $6,000. Total savings over 5 years: $41,000; over 10 years: $94,000.
“People are often surprised by the amount of energy savings from simply changing how existing systems operate,” says Anna Levitt, UC San Diego’s assistant energy manager. “The energy savings are huge!” Anna would know. Through campus-wide lighting retrofits, her team has helped UC San Diego save an astounding $6.8 million in the past three years (2009-2012). “Because it is a new technology, [LED bulbs] cost more to buy up front. But you have to look at it as a long-term investment,” Anna advises.
Many businesses are doing just that: taking additional costs into account, such as energy use and bulb replacement. LEDs beat incandescents and CFLs every time. Birch Aquarium’s new LED bulbs will last at least five years–that’s five times longer than a CFL and 41 times longer than an incandescent bulb (imagine having to purchase and install a bulb once versus 41 times). Some extreme LEDs have a projected bulb life of 100,000 hours, meaning that if you left a light on without ever turning it off, it could still last 11 years. And with average use? Almost three decades. With more manufacturers recognizing the benefits of LEDs, prices continue to drop. “The price has definitely come down since I began investigating LEDs for UC San Diego,” Anna recalls. “We’re starting to think of them as a standard practice-technology for the campus.”
The bottom line re-envisioned
LED lighting enhances the beauty of museum galleries. Exhibit staff no longer need to scramble up and down ladders every five to seven months to change out “hot potato bulbs.” Compared to other types of bulbs, LEDs waste little energy as heat—they light homes and offices, not heat them. Businesses save money by reducing their energy costs. Another important benefit is that LEDs don’t contain mercury—a drawback of CFLs, which need to be disposed of as toxic waste. And, close to the heart of Birch Aquarium, energy-efficient lightbulbs reduce the amount of fossil fuels burned to generate electricity, helping to mitigate climate change and increasingly acidic oceans. Curbing carbon dioxide and other harmful emissions also reduces air and water pollution.
People sometimes assume “sustainability means sacrifice,” but that’s a mistake. Energy-efficient business practices are a win-win-win strategy, yielding profits while benefiting people and the planet. Of course, using technology to relieve the pressure we exert on natural systems is only part of the solution. But watching the creative strides that people are making in this direction is thrilling. To see scientists and engineers working through ideas, eliminating what doesn’t work and testing what might… What simple yet elegant innovations will make our lives better? The lives of other species better? And how many of those innovations will come dressed, like a lightbulb with cooling lens holes, in understated yet ingenious fashion?

Gray whales are on the return leg of their annual migration, heading from Baja California’s breeding lagoons to the Bering and Chukchi seas in the Arctic. Map source: Wikipedia, Creative Commons
A whimsical welcome letter to gray whale calves from the imagined “Bering & Chukchi Seas Dining Services.”
Dear Gray Whale Calf,
Congratulations on completing your first northbound migration!
Welcome to the Arctic Ocean. This is where many gray whales feed during the summer (and soon, so will you). Swimming 85 to 100 miles a day on the northbound migration burns a lot of calories—it’s time for a hearty Arctic meal. Before you know it, you whales will migrate again, so it’s important to pack on the pounds.
Here, in the nutrient-rich waters between Russia and Alaska, there is a seafood smorgasbord! Patches of the muddy seafloor are full of baleen whale delicacies: shrimp-like animals called amphipods, worms, fish eggs, and molluscs. The body fat you gain from these foods will nourish you during the next migration (when you rarely feed).
This is also an exciting time, because shortly, you will no longer need to drink your mother’s milk. This summer, you will begin mimicking how she feeds while accompanying her on dives to the amphipod beds.
Learning to strain prey from the seafloor can be challenging for some calves at first. Most aren’t used to the feeling of mud between their baleen plates. Others worry about their mouths constantly being exposed to frigid Arctic water. But gray whales have special blood vessels at the base of their tongues to reduce the amount of heat that dissipates when you feed. In fact, scientists were surprised to learn that a calf loses more heat through its blubber than its tongue!
Gray whale head and mouth.
If you can’t find enough food, move to another area. Follow the lead of other gray whales, which have been traveling farther north in the past two decades. You can also switch behaviors and feed on another type of prey. Biologists think gray whales are an intriguing marine mammal because you have flexible feeding strategies. Not only can you suction feed, but you can suck or skim swarming shrimp and crab larvae from the water and engulf small fish. Gray whales that spend their summers near British Columbia and Washington use this feeding technique.
Mom will stay by your side for the next few months, but by winter, you will be a fully independent gray whale and responsible for finding all of your own food.
Best of luck and happy grazing!

By Audrey Evans, whale watching coordinator
Earlier this season, Birch Aquarium at Scripps teamed up with Andiamo Tour Mexico to embark on a remarkable expedition to two gray whale breeding lagoons in Baja California, Mexico. Our lucky participants were met with unique and life-changing experiences as gray whales (called “friendlies” by some) interacted with them—behavior seen nowhere else but in these lagoons.
February and March are prime months to catch more than just a glimpse of these giants in their wintering grounds, where many congregate to mate and give birth. Our adventure to the lagoons began as 37 participants crossed the U.S./Mexico border. We ventured south, listening as our knowledgeable Andiamo guide discussed Mexican culture, landmarks, and history.
The chartered bus ride was a fascinating learning experience, especially as we gazed at the changing Baja California scenery. Sandy sea cliffs turned into rolling green hills that ultimately gave way to an open desert landscape peppered with giant boojum trees and cardón cactus. As we crossed the state border into Baja California Sur, we drew closer to the breeding grounds of the gray whale.
Gray Whale History
The first lagoon we reached was Laguna Ojo de Liebre, which translates to “eye of the jackrabbit,” referring to the shape of the lagoon. “Scammon’s
Lagoon” is another common name. The latter name stems from a 19th century whaling captain, Charles Scammon, who came in search of overwintering gray whales. These whales were hunted relentlessly for oil (used as lamp fuel) and whalebone (baleen), which made products including ladies’ corsets and umbrella ribs.

Gray whales are slow-moving and adhere to predictable migration routes that place them mostly in coastal waters; this made them easy targets for whalers. Overhunted, gray whales have come close to extinction two times in the last 150 years before they were officially protected. Today, the Eastern gray whale population is more than 20,000-strong, estimated to be close to the historic pre-whaling size. It is truly a conservation success story driven by changes in U.S. and Mexican laws as well as our own perception of these remarkable animals.
When peering across a whale-studded lagoon, people no longer see a gold mine. Instead, our modern perspective sparks a fascination with these creatures. Visitors are treated to an intimate look into the lives of a truly wild animal. There is no food or other reward offered to entice these whales to approach humans; their level of curiosity is as mysterious as it is awe-inspiring.
Meeting The Locals
Our first close encounter with the “friendlies” included a cow and calf pair. The cow appeared older, wearing large patches of cream-colored barnacles, which often grow with age. She initially surfaced about 20 meters from our Panga boat with her small, dark-colored calf close in tow. The Panga driver turned off the engine and within minutes the two curiously made contact with us. At this close range we were able to get a good look at the pair.

Calves are typically darker than adults, as they do not yet have the characteristic patches of symbiotic organisms. Up close, we could see the adult’s barnacles attached in clusters. Barnacles start out as free-swimming larvae and then settle onto a firm substrate—in this case whale skin. They eventually create a hard shell as they grow into adults and use feathery legs to filter plankton and other organic material from the water.
The gray whale barnacle, Cryptolepas rhachianecti, is host-specific and can only be found on gray whales. Orange-colored whale lice often surround each cluster of barnacles. These lice feed on dead skin and, like the barnacles, are a type of crustacean (different from the insect lice found on terrestrial mammals).
We appreciated our first-hand look at these tiny hitchhikers. While the calf lacked these organisms, it had noticeably distinct dimples on its rostrum (“snout” area). Each dimple possessed a single stiff hair in the center, which served as an example of the whales’ mammalian characteristics. Each time the cow and calf took a breath, we not only heard the exhale, but were surrounded by the expelled water vapor, feeling it on our faces. Despite some minor bad breath, this was an incredible encounter!

Only a day later, we found ourselves launching into another breeding lagoon: San Ignacio. This location is a little further south and a bit more remote. Within 30 minutes, we were met by more curious “friendlies.” Two adults traveled back and forth, inspecting our Panga and another nearby. Amazed, we watched as the whales spyhopped (peered with their head above water), returning beneath the surface to swirl their flukes just beneath our boat. Repeatedly, each approached within an arm’s length, again making contact with humans.
On a third outing, we returned to Ojo de Liebre and observed a mating trio. Gray whales typically mate in groups containing two males and one female. Chasing, splashing, and rolling occur before the female ultimately decides to roll with one of the males. Understandably, this group ignored our boat even though they came within 10 meters of us.
During the rest of this final 3-hour tour, we witnessed several whale breaches, more spyhopping, and one whale nearly motionless as it logged (“slept”) just beneath the surface. We were all too pleased to have another cow and calf appear for a close visit. As difficult as it was to leave the whales that day, we were grateful to have made so many priceless memories.
Along our return journey north, we reflected upon our encounters with the whales. Each participant shared personal stories, whale photos, and even email addresses. To have such contact with wild animals is truly unique. To share such experiences with fellow human beings creates another special, perhaps less-anticipated, connection. Each of us now shares a new perspective on the gray whale, one which we’re likely never to lose.

Volunteer Don Ward
Join us in celebrating our April Volunteer of the Month: Don Ward!
Many visitors and staff know Don as a somewhat permanent fixture at the aquarium. That’s no surprise considering he’s been a volunteer at Birch Aquarium at Scripps for the past 12 years, often spending two afternoons per week and even some evenings at the aquarium. In 2012, this added up to 500+ hours of volunteer time.
On Wednesdays and Fridays, Don can be found on his “beat” — making the rounds in the Hall of Fishes and elsewhere, answering questions, and leading tours. He offers invaluable assistance at the tide pools during feeding times, talking with visitors so the aquarists can get to all three pools to feed the critters.
Always proactive and prepared, Don’s natural tendency to be an ambassador for the aquarium lends itself perfectly to his work on our whale watching tours as well. When he’s not doing all this, he mentors our newer volunteers and keeps our entire volunteer team entertained with his quick wit and sharp intellect. Don’t let his wry humor and jokes fool you; Don takes his leadership role very seriously and works hard to ensure that everything is running smoothly.
Staff and volunteers alike value Don’s contribution of time and dedication. He is truly a champion for Birch Aquarium at Scripps and what we represent. Congratulations Don!

A blanket of coastal fog is clearing as whale watching boat Marietta edges out of San Diego Bay. Higher-than-expected waves catch many passengers off guard, but the surprise seems to bring this group of strangers closer together. Two young men on the bow are engaged in an amusing debate as to whether or not they feel seasick. One of them flags me down for a second opinion.
After chatting for a few minutes, I learn that Phil Shu is one of several study abroad students on board from Grossmont College. “I am from China and am studying psychology in San Diego for one year… I have been to all the major cities in California,” he says, grinning.
As the Marietta motors west, I gaze at the horizon and envision how far Shu has traveled. With an unlimited fuel supply, we could (hypothetically) head west from San Diego, along the 32°parallel, and reach his home country. China is out there somewhere….across this vast Pacific Ocean, which covers one third of the planet and is larger than all the continents combined.
To date, visitors from six continents and 38 countries have joined Birch Aquarium and Flagship Cruises & Events for whale watching this season (see map). They’ve come from all walks of life: A giggly bunch of friends circling the globe. Finnish doctors attending a medical conference in San Diego. An 81-year old widow on a trip that she and her husband wanted to take. All here to see whales…

A mile north of Point Loma, we spot a blow. This gray whale is sneaking along the kelp forest edge, its head barely breaking the surface when it breathes. The passengers are also taking slow, shallow breaths, waiting for the whale to reappear. Everyone clusters together, hugging the rail with cameras at the ready. I walk around the crowd, my ears vigilant for foreign languages. French here, a little German over there. Italian, che bello! Is that Vietnamese? I am humbled by the number of languages I don’t speak. And yet, there is meaning in a warm smile or an arm around a spouse’s shoulders; even squabbles among siblings. These are universals we all understand.
Storytelling is another way we all communicate, and on the boat, accounts of other U.S. states and distant countries are told daily. Through our passengers’s memories, I have worked as a travel writer and dined at some of the finest cafes in London. A blue whale has breathed in my face and a pod of orcas has surfaced behind my boat. I have walked along the shores of Lake Baikal in Russia, where the only freshwater seal lives. Rain has soaked the floor of my house in Mongolia. Perhaps this is why people enjoy discussing travel so much—we get the chance to revel in someone else’s adventure. And, in a small way, that person’s experience becomes part of our own.

Marietta is returning to San Diego Bay. Near the mouth, a bait ball has begun to form, attracting the attention of hungry common dolphins and Brown Pelicans. Overhead, chattering Caspian Terns survey where to dive amidst the commotion. Three excited kids jump up and down, pointing at a V-formation of cocoa-colored cormorants flying in from the south.
At the start of the tour, most passengers had not seen a whale outside of captivity. Some had never been on a boat before. But now they have direct experience with whales and the open ocean. Soon, we’ll approach the dock and our guests will head their separate ways. But these travelers will take stories of the Pacific Ocean home with them—to Argentina, Portugal, Iran, and New Zealand. Whether a person lives in a country with bold conservation policies or weak ones, passengers disembark with a heightened sense of adventure and empathy for ocean wildlife.
Is this appreciation for the living world strong enough to cross state and international boundary lines? Can we reconcile cultural differences for the greater purpose of valuing our common humanity? If Birch Aquarium’s whale watching passengers were a model for the world, I would say: maybe…maybe we can.

Birch Aquarium’s coral habitats feature captive-raised coral to lessen our impact on the environment.
A study released this week by marine biologists from Scripps Institution of Oceanography at UC San Diego provides the basis for a new, non-invasive way scientists can assess the health of corals in the wild, a discovery aided by Birch Aquarium’s staff and the aquarium’s live coral collection.
Scripps researchers Melissa Roth and Dimitri Deheyn discovered that little-understood fluorescence—or light—produced by corals can be an indicator of stress, and subsequently, their overall health. The new findings will have a significant impact on how scientists monitor the vitality of these unique and productive ecosystems, which are under threat from warming seas and ocean acidification.
To conduct the study, Scripps researchers worked closely with Birch Aquarium’s husbandry team, which nurtures captive-raised coral onsite. Our aquarists supplied the researchers with fragments of Acropora yongei, a common branching coral that builds reefs in the Indo-Pacific Ocean, so they would not need to collect from the wild. Our aquarists also provided critical husbandry expertise throughout the study, such as maintaining lighting and water movement in the experimental tanks.
In their lab, Roth and Deheyn tested the coral under various temperatures and found that fluorescence dropped when the organisms were introduced to cold or heat. Corals exposed to cold temperatures were able to adapt; corals exposed to heat bleached (lost their symbiotic algae).
As the public outreach center for Scripps Oceanography, Birch Aquarium at Scripps is thrilled to be a part of this cutting-edge research and we’re excited to share researchers’ findings with our visitors.
Dr. Andy Nosal poses with a local leopard shark.
Summer is just around the corner, and we have big plans for it! We’re thrilled to announce a new initiative at Birch Aquarium at Scripps and introduce a new member to our team: Dr. Andy Nosal.
As our DeLaCour Fellow for Ecology & Conservation, Andy, a marine biologist at Scripps Institution of Oceanography, will spend the next three years working with Birch Aquarium and sharing his scientific discoveries with our visitors. Andy earned his Ph.D. from Scripps in December and specializes in shark ecology, with a particular focus on La Jolla’s population of leopard sharks.
July & August 2013 will be “Shark Summer” at Birch Aquarium at Scripps. We’re celebrating our local populations of leopard sharks and their cousins with a new exhibit, dozens of shark-related public programs, and lots of interaction with Andy for our visitors.
Stay tuned for information about these programs and Andy’s research down at La Jolla Shores, where he’ll be flying a weather balloon along the shore this summer to track leopard sharks, research that has important implications for local shark conservation efforts.
We hope you’re as excited as we are to embark on this new initiative!

Is it mid-March already? That means we have just about a month left to cruise the Pacific in search of gray whales with Birch Aquarium naturalists.
We’ve seen some amazing sights lately aboard Flagship Cruises & Events’ Marietta. Among sightings of dolphins, sea lions, and coastal birds, eager whale watchers have been extraordinarily good at spotting blows in the distance.
We find gray whales simply by looking to the horizon and scanning for signs of their presence. From a distance, the first sign is their blow. An adult gray whale’s heart-shaped blow can stretch as much as 15 feet high, which immediately alerts everyone on board that they are close by.
A gray whale’s iconic heart-shaped blow.
Juvenile whales are a different story, and we’ve been encountering them most often these past few weeks. Significantly smaller than their adult, 45-foot long counterparts, these immature whales measure only 20 feet or so depending on their age. Their blows are very small and hard to see. It takes a trained eye and good timing to spot these individuals. Good thing we have both on the boat!
One day this past week, the Marietta was headed out to sea when, just a mile offshore, Captain Hieu slowed the boat to a crawl. He was sure he saw something up ahead, and he was right! That day, our passengers saw one of the smallest northbound gray whales that our onboard experts had ever witnessed, about 15 feet long. This whale’s course was strong, steady, and unwavering; someone was ready to get back home to the Arctic! It’s very important to give these amazing travelers space, so after trailing for a while, we bid the whale goodbye. It was amazing to see such a strong and independent little gray whale.

It’s not too late to whale watch with Birch Aquarium and Flagship Cruises & Events. You never know what you’ll see, but it’s always a pleasure waiting for what the ocean shows us.
