Contributor: University of Aveiro (Portugal) Postdoctoral Researcher Luciana Genio Knowing where and for how long the pelagic larvae of deep-sea benthic animals live in the water column is extremely important to understand how populations respond to natural (e.g., climate and food supply) and human (e.g., pollution, overfishing, mining) disturbances. On this cruise, we deployed a …

Over the 30-year (and counting) time-series study at Station M, we have seen changes in the biological carbon pump with changing sea surface conditions along the California coast. The abyss is not the invariable environment most people once envisioned. Short-term processes and events can have major impacts on long-term patterns. Every two hours, the Sedimentation …

MBARI engineers recently tested a new long-range autonomous underwater vehicle that is designed to detect and track oil spills.

The Benthic Rover is a fully autonomous underwater vehicle that collects data for the Pelagic-Benthic Coupling Lab’s studies of seafloor carbon consumption. Capable of yearlong deployments, it is the only untethered underwater rover in the world operating at abyssal depths. The Rover has transited over 11 kilometers of abyssal seafloor at 4,000 meters depth since …

MBARI engineers recently tested a new version of a camera system to study groundfish on deep, rocky reefs.

A new paper shows that currents in submarine canyons often involve large-scale movement of the seafloor. This discovery could help ocean engineers avoid damage to pipelines, communications cables, and other seafloor structures.

We’re heading home! During this cruise, we completed 25 ROV dives, collected 130 vibracores, and 348 push cores. This totals over 20,000 centimeters of sediment cores collected during this expedition. Of those samples, we sliced, bagged, and labeled over 2,000 one-centimeter slices of mud and sand. Now the next phase begins: we analyze all these samples to understand …

In the last two weeks aboard the R/V Western Flyer, we’ve spent 24 ROV dives cruising across the seafloor offshore Southern California, collecting sediment cores. Much of the seafloor we have surveyed is flat, muddy, and brown. So, one can imagine the eruption of excitement when we see a cool deep-sea animal. More notable organisms …

Along with scientists from MBARI and the U.S. Geological Survey, we have two graduate students and a postdoctoral researcher from Stanford University on the R/V Western Flyer with us. Each is interested in something slightly different but all are eager to help out and gain first-hand experience with the many tasks required to complete this research. …

Each day starts at 6:00 a.m. with preparing the ROV Doc Ricketts for the first dive of the day. Preparations include making sure we are in the correct spot on the map and all our sediment coring equipment is ready to go on the ROV. The ship’s stellar crew and ROV pilots jump into coordinated …

If you take a styrofoam cup into the deep sea, the immense water pressure will squeeze all the air out of the cups compressing them into miniature versions of the original cup. The deeper the ROV goes, the smaller the cups get as more air is squeezed out. Prior to departing, we packed cups decorated …

Yesterday, we set sail for the Southern California expedition. At the start of every cruise a safety meeting is held for all the participating scientists to learn how the Western Flyer is run and to go over all the ship rules and safety protocols. During our long transit south, we made a short stop offshore …

MBARI and the Monterey Bay Aquarium co-host symposium that is bringing together researchers from at least 34 countries.

MBARI and Monterey Bay Aquarium leaders will be participating in the Global Climate Action Summit in San Francisco.

Researchers from MBARI and the National Oceanographic and Atmospheric Administration are testing a new underwater robot that will swim around Lake Erie monitoring algae and toxins in the water.

Today is the last day of this research cruise. Our station is in the bay and we awoke to feeding whales surrounding the ship this morning. We will recover the MRS, put all our samples away, clean the lab, and head back to the beach. It has been a productive and interesting expedition for all the researchers, but we are looking …

Yesterday was an early start with a goal of retrieving the MRS from the 2,000 meter mooring. During the dive, we spotted a rare deep-sea jelly, Vampyrocrossota childressi and a very full black swallower, Chiasmodon niger.

Data from a network of robotic floats carrying high-tech sensors suggest the Southern Ocean may take up much less carbon dioxide from the atmosphere than expected.

Smithsonian National Museum of Natural History Postdoctoral Fellow Chan Lin My goal here is to collect amphipods, specifically from the genera Paraphronima, Cystisoma, Streetsia, Lanceola, and Scypholanceola. Each of those hyperiids has a distinct eye type. I am interested in studying how their vision works and how their visual world is represented in the brain. This is my first ever …
