On today’s final dive of our expedition series, MBARI’s Benthic Ecology Group, working with Janet Voight (Field Museum Investigative Research Center) and Julia Sigwart (Coastal and Marine Sciences Institute, University of California, Davis) are revisiting this work. Late Friday evening, the ROV Doc Ricketts’ large drawer was neatly loaded with forty-one, 1’ x 4” x …

Research in the depths of the Gulf of California give scientists a clue as to how climate change could affect fish communities.

Gregory Bongey Should you ever find yourself as a marine science student in your fifth year of a master’s program, your first, second, and third priorities are to defend your thesis as soon as possible. Unless of course, you receive an unexpected opportunity to join MBARI on a deep-sea research cruise. In that case, practicality …

Andrew DeVogelaere Today we split the science team to run ROV operations while preparing to relaunch our large, physical oceanography mooring. That allowed us to have an extra exploration dive at Davidson Seamount today. There is always a special excitement about exploration dives because we get to view areas that no human eyes have ever …

After two days working at Davidson Seamount it was time to return to Sur Ridge to find the Deep Coral Cam we dropped off on the first day of the cruise and move it to the spot where it will spend the next nine months. Before heading to Sur Ridge, we steamed back to Monterey …

Amanda Kahn Today was a mixed day of deploying and recovering moorings along with an ROV dive. In the morning, the sediment trap mooring we recovered yesterday was redeployed at the top of Sur Ridge. The sediment traps will remain there until December, collecting marine snow that rains down from the ocean’s surface. Corals and …

Andrew DeVogelaere After months of preparation and a full day of loading equipment, the crew boarded R/V Western Flyer at 4:00 a.m. Our main destination for the research cruise is Sur Ridge and its dense forests of deep-sea corals and sponges. Sur Ridge is located 45 kilometers (28 miles) west of Point Sur, near the …
