Gulf of California 2015, Leg 3 – Biodiversity and Biooptics – Log 9

Cruise Highlights We are now even closer to La Paz and are heading down to 1,600 meters with the ROV for one last look in the deep waters of the Gulf of California. The divers have dried their gear and packed it away as there will be no blue-water dive today due to time constraints. …

More deep-sea fauna Rebeca Gasca writes: This is a new, exciting opportunity to work with colleagues at MBARI and other institutions, all interested in exploring the peculiar and poorly-known fauna dwelling in the water column but especially in deep waters. The ROV Doc Ricketts is collecting valuable biological samples and enabling us to discover fauna that can’t …

Hyperiid Amphipods and Ctenophores Bill Browne writes: I am investigating the genetic patterns underlying animal diversity. To me, the two most interesting groups of midwater animals in the Gulf of California are the hyperiid amphipods (bug-like crustaceans) and ctenophores (comb jellies). Why hyperiids? Many midwater organisms have unusual eyes. Hyperiid amphipods have a particularly impressive …

Bioluminescent Organisms Darrin Schultz writes: I work in Steve Haddock’s lab where I study bioluminescent organisms, animals that make their own light, much like fireflies. On our leg of the Gulf of California expedition, we have seen and documented many luminous creatures, including jellyfish, shrimp, fish, comb jellies, worms, tiny crustaceans, and even “glowing dolphins” …

Diving for Jellies in Mexico Wyatt Patry writes: At the Monterey Bay Aquarium we collaborate closely with our sister institution, MBARI in many diverse ways. As a Senior Aquarist my primary goals are to find new jellies to display and develop innovative ways to share them with our guests. I jump at every chance to …

Siphonophore Evolution and Development Cat Munro writes: I am a second year graduate student in Casey Dunn’s lab at Brown University, and this is my third cruise aboard the Western Flyer. I’m interested in siphonophore evolution and development. Siphonophores are long rope-shaped animals that are relatives of corals and jellyfish. Siphonophore larvae bud off new “bodies” (also …

Larvaceans, Jellies, and other Animals George Matsumoto writes: My primary research interests are split between larvaceans and jellies. On the basis of MBARI’s 2003 Gulf of California expedition where we found thick layers of giant larvaceans at a depth of 15 meters, I have been hoping to investigate the fluid flow patterns within the inner …

Exploring Farallon Basin For today’s ROV dive we took a second look at Farallon Basin. Diving in the same location for two consecutive days gives us a chance to conduct night operations (such as trawling) and the opportunity to see how the water column changes day by day. From our dive video it would have …

Gulf of California 2015, Leg 3 – Biodiversity and Biooptics

On this leg, researchers will study physiology and diversity of midwater animals in the Gulf of California’s central and southern basins. They are especially interested in gelatinous species which also have populations in Monterey Bay. Many midwater species are found in both Monterey Bay and the Gulf of California, despite differences of up to 15° …

Research Goals for the Biodiversity and Biooptics Leg The R/V Western Flyer set sail on Saturday, March 7th, at 7:00 a.m. the third leg of the MBARI 2015 Gulf of California Expedition. Led by Steve Haddock, MBARI researchers and collaborators onboard during this leg specialize in molecular studies of “gelatinous zooplankton”—jellyfish-like siphonophores and ctenophores that can dominate …
