Morgane Le Saout 45o 33.7′ N 129o 55.4′ W The goal of this dive was to sample the different flows from the valley of the eruptive axis of the Vance Segment toward the eastern flank of the South Rift of Axial Seamount. The Vance Segment is the next spreading ridge segment south of the one …

45o 59.4′ N 130o 1.5′ W Our dive today started with biology collections at the CASM (an acronym for Canadian American Seamount) vent site on the northern caldera floor at Axial. Then we headed north up the caldera wall and crossed several old, heavily sedimented flows, and ended with geology collections on two flows that …

44o 39.5′ N 130o 21.9′ W Today’s dive started at the same point as our short dive yesterday at a hydrothermal vent site that was named “Vent 1” by the US Geological Survey (USGS) years ago. Our priorities today were to do the fluid sampling we ran out of time for yesterday at the same …

Shannon Johnson, Robbie Young, and Corinna Breusing 44o 39.5′ N 130o 21.9′ W After a terribly long and miserable transit the weather calmed a bit and what was to be a quick test dive became an exciting reprieve from boredom, seasickness, and an otherwise helpless feeling that we’d never get any science done. We had …

43o 43.4′ N 129o 45.8′ W at 2200 Well, we are making progress! We will pass over the Blanco transform fault zone during the night and reach our first (fingers crossed) dive target in the morning. We have had to change our dive plans considerably because of the weather. We were unable to dive at …

41o N 127o 29.5′ W at 1500 We are crossing the Escanaba Trough of the Gorda Ridge right now, five kilometers south of NESCA (Northern Escanaba Trough). NESCA was to have been our first dive target of this expedition but the weather continues to be awful. We held a small ceremony, waving and blowing kisses …

A newly designed seawater sampler promises to automate monthly water sample collection, freeing up ship and personnel resources for other research projects.

39o 44.8′ N 125o 29.55′ W at 1800 in the evening The wind picked up all day and with it the swells. This evening we are now SW of Cape Mendocino and heading NNW at about five knots. It is overcast; the wind is blowing 35 knots from the north and “it has definitely gotten …

121o 47’ 13” W, 36o 48’ 16” N Our departure was timed with the high tide and we slipped from the sleepy, foggy, calm waters of the harbor into Monterey Bay right on schedule. We are eagerly anticipating exciting science on the ROV dives ahead, but we’re not at all excited about the windy weather …

Last Thursday, the American Geophysical Union (AGU) awarded the prestigious Maurice Ewing Medal to MBARI marine chemist Peter Brewer. This medal is given annually to recognize “significant original contributions to the ocean sciences."

Each winter, large white sharks leave the California coast and swim halfway to Hawaii, congregating in an area known as the “White Shark Café.” By attaching a miniature video camera tag to a white shark’s fin, researchers at the Monterey Bay Aquarium and the Monterey Bay Aquarium Research Institute (MBARI) hope to collect video footage that shows—for the first time ever—exactly what the sharks are doing out there.

During MBARI’s annual Day of Engineering, Science, and Technology, the staff presented new research and development to the institute’s board of directors. Wide-ranging presentations and a “tools of the trade” walking tour comprised this year’s special day, which focused on the theme “extending our reach”.

This week MBARI joins the Monterey Bay Aquarium, Science Friday, and other organizations in celebrating Cephalopod Week 2016.

In early June researchers from MBARI and the Monterey Bay National Marine Sanctuary traveled to Sur Ridge to study the corals and sponges that grow on this fascinating underwater mountain.

This unusual hydrothermal vent is one of many discoveries from a Gulf of California expedition highlighted in the 2015 Annual Report. The publication also features several science and engineering projects conducted close to home in Monterey Bay and includes a preview of some of the institute's emerging technologies.

Engineer Thom Maughan created a lot of buzz at MBARI when he left a blue fiberglass shark fin in the upstairs lobby.

Five axes are better than three when it comes to milling parts for complex technology. Ray Thompson, MBARI’s machine shop supervisor, remarked that a 5-axis machine allows our scientists and engineers to “design around the technology”.

The smallest member of the MBARI seagoing fleet, the R/V Paragon, often runs multiple missions in a day.

Over the past week, a team of engineers from the Schmidt Ocean Institute (SOI) have been testing their new remotely operated vehicle (ROV), SuBastian, in MBARI’s test tank.

About a week ago, MBARI marine chemists Hans Jannasch and Ken Johnson went on a little boat ride, chasing an open-ocean profiling float that was drifting in the California Current, about 100 miles offshore.
