Kessil is making headlines today with the recent announcement of their very own controller, called the Spectral Controller. This new device, which is said to be the size of a smartphone, is designed to work specifically with the Kessil A360 LED light and all future releases. It has the ability to control up to two different sets of lights via two separate 0-10V output ports, but don’t translate that as just two different lights. Instead, the Spectral Controller can program multiple lights spread across two separate “groups”. A prime example would be lights over two different aquariums or if you use a Kessil fixture for your refugium, you could change the lights over the display tank independently of the refugium light. Powering the controller is a micro-USB that can be plugged into a wall outlet or computer USB port. When not plugged in, the controller retains all programs and settings, so all of that hard work isn’t lost when the controller is taken offline. by Matthew Stansbery | May 19, 2014 | Conservation, Corals, Science

When I tell people that we’re in the field collecting saltwater animals for display and research at the aquarium, most of them imagine that the actual catching is the hard part. In reality, the hard work starts after we collect the animal. Keeping animals healthy in the field—and then healthy while en route back to Manila for a 14-hour flight to their new home in Golden Gate Park—entails an entire slew of life-support equipment (LSS). We have that stuff at the Academy, obviously, but right now we’re out in the field. Where it’s too hot. Where there isn’t a store to buy what we need. Where we have to constantly battle a continually moving colony of fire ants that appeared right where we set up our equipment. Fortunately, all the pre-planning we did to prepare for this is paying off. Want the laundry-list of what came with us on the plane? Two 200-gallon inflatable kiddie pools (plus a third, just in case), 220-bolt air and water pumps, rolls of tubing, nets, containers, coral-holding devices, fish-holding cups, seeded biofilters, and an assortment of valves, glue, patch kits, rubber bands, cable ties, etc. We knew we’d need to keep water temperatures down in the pools so the animals could survive (from 94 degrees to a reasonable 82), so our original plan was to give the pools water-changes every few hours, which would have required many trips hauling 5-gallon buckets of water 30 feet back-and-forth from the shore. Luckily, our hosts were able to find a powerful sump pump and modify it so it could stay in the ocean while plugged in. We were also able to connect the two pools via four siphon hoses, basically turning them into one body of water. Then we able to fabricate drains in the pools, which gave us not just cooler temps, but also stronger water flow—much better for the shallow-water corals (which are, as the kids say “money”), two coconut octopuses, and selection of fish we’re caring for (which includes ghost pipe fish and white mushroom coral pipefish). And today we’re going to attempt to collect pigmy seahorses. Many of the fish collected deeper than 300 feet have a gas-filled swim bladder. When they’re brought to the surface, the pressure on them decreases and the gas in the swim bladder expands in the same way a sealed bag of chips does when you take it on an airplane. When the bladder expands, it can damage the internal organs of the fish—which is, well, very bad for the fish. Traditionally, collectors have used a hypodermic needle to relieve pressure from the swim bladder, but that’s a less-than-optimal solution, resulting in unreliable survival. To combat this problem, we designed and built a fish decompression hyperbaric chamber based on some larger designs that have been used for collecting cold-water rock fish. Our design is light, relatively portable, and the collection chamber itself doubles as the decompression chamber. The deepwater team collect the first deepwater fish yesterday, and our chamber is working very well. Tomorrow morning, Aquarium Team One heads home to the Academy with the live animals we’ve collected. Packing and shipping them is a story in and of itself, which I’ll try to write up on the plane. Next week, Aquarium Team Two arrives for more collecting with a focus on the deep-water fishes. I’m looking forward to getting home, unpacking the animals, and seeing what the second aquarium team achieves next week. —Rich Ross, Aquatic Biologist by Rich Ross | May 13, 2014 | Corals, Fish, Invertebrates, Science
Greetings from Aniloa! After three and a half days of collecting in the field, we’ve amassed a nice collection of corals, invertebrates, and fish to ship back to the Academy—here’s a quick overview. The sites we’ve visited thus far include Twin Rocks, Devil’s Point, Bethlehem, Mapating Point, Dari Laut, Matu Point, and Anilao Pier, and we currently have 70 specimens on hand. They come from varying genera—Acropora, Fungia, Turbinaria, Tubastrea, Sinularia, and Sarcophyton—and they’re being kept in a temporary field aquarium set up at the Anilao Beach Club. (Rich Ross will be blogging about that setup later, so I won’t go into it here.) We were also able to acquire three snake anemones while on a night dive at Anilao Pier, and we’ll continue our quest for the elusive Bobbitt worm tonight during another night dive at the same location. Oh, and one more highlight: On this afternoon’s dive at Matu Point, Rich was able to collect a pair of ghost pipefish, which were way up there on our list of acquisitions for this expedition. With a couple more days of diving and collecting ahead, Aquarium Team One should be on track to collect most, if not all, of what we have set out for on this trip. —Seth Wolters, Assistant Curator for Steinhart Aquarium by Rich Ross | May 12, 2014 | Corals, Equipment, Fish, Science
Checking in for a 14-hour flight is always a good time. Checking in for a 14-hour flight with 11 items (three suitcases, five Action Packers, two bags, and Steinhart Director Bart Shepherd’s guitar) between three people is an amazingly good time. We started planning for this expedition in earnest five weeks ago, and considerable effort went into making sure our bags were under size and weight limits—a not insignificant task when equipment needed for the expedition includes Bobbit-worm catching devices, a series of newly designed hyperbaric chambers (for decompressing fish hand-collected below 300 feet), a ton of SCUBA and rebreather gear, and myriad other critical items needed to collect and ship live fish and corals from the Philippines back to Golden Gate Park. As it turned out, our packing efforts were worth the time we put into them, as all of our luggage was deemed to be within weight limits. Sadly, though, there was one piece of luggage that stayed in San Francisco because it couldn’t be hand-carried onto the plane, and we were scared it wouldn’t make it through the checked baggage experience. Oh guitar, we will miss you. The first aquarium team arrived safely at the Anilao Beach Club and enjoyed a delicious breakfast overlooking the Verde Island Passage. As soon as our luggage (which arrived in Manila in great shape, but is currently stuck in traffic) arrives on-site we’ll begin setting up scuba gear and animal holding. Then, the real work begins. —Rich Ross, Aquatic Biologist
