During a recent survey off the coast of Big Sur, MBARI researchers discovered thousands of mysterious holes or pits in the seafloor.

In a new paper in Science magazine, researchers describe an experiment that turned the seafloor cable on MBARI’s MARS ocean observatory into the equivalent of 10,000 seismic stations on the ocean floor.

Henk-Jan and Stella Scheer We are guest scientists from GEOMAR Helmholtz Centre for Ocean Research Kiel and are very happy to join the MBARI midwater expedition on the Western Flyer. During this week, we have been documenting and collecting a range of midwater animals. Such in situ observations provide much more than an image alone. …

The word from Captain George Gunther was that we might have a short dive Tuesday due to deteriorating weather. This was seconded by the modern sailor’s favorite tool, windy.com. But first thing in the morning, the winds were light and we began our dive at 6:30 a.m., as always, feeling optimistic and excited about what …

Kat Bolstad It is wonderful to be back at sea. I’ve had the honor of sailing with the Western Flyer crew several times before, but not since 2015 (life and small children have happened in the meantime), so it’s great to be back aboard. And this cruise has gotten off to a wonderfully squiddy start for me—I lead …

Updates from researchers on the R/V Western Flyer: Sunday, November 17, 2019 Astrid Leitner We started out at our deep dive location just outside Monterey Bay on Saturday. We dove all the way to the bottom to about 3,000 meters (9,800 feet) where we deployed Henk-Jan and Stella’s bait package and filled up the Midwater Respirometry …

We departed Moss Landing on Friday heading out to our first dive location on the south side of Monterey Canyon. The weather and sea conditions were pretty calm making for a nice beginning to our seven-day expedition. There are a lot of different objectives for this week but, luckily, the science team is flexible and …

New website brings together relevant ocean conservation data into one easy-to-use platform.

Ocean lovers can now listen to the sounds of Monterey Bay live on the web or through Amazon’s virtual assistant, Alexa.

MBARI researchers recently found that animals living on the deep seafloor are much less likely to produce light than those swimming or drifting in the “midwater.”

A new exhibit at the Monterey Bay National Marine Sanctuary Exploration Center features recordings from MBARI's deep-sea hydrophone.

MBARI Senior Research Technician Roman Marin III passed away unexpectedly last month.

A just-released scientific report connects a host of ocean changes with human activities that take place largely on land.

Climate change has serious, long-term, and far-reaching negative consequences for our ocean. We present facts and resources to learn about climate change and the ocean.

Researchers test methods to restore deep-sea corals via translocation at Sur Ridge.

A new study shows how the amount of humpback song in Monterey Bay varies over days, months, and even years.

A new paper summarizes the quirky sexual and reproductive behaviors of octopuses, squids, and their relatives.

In a recent study, researchers compiled data from 18 years of rare video observations on deep-water skates.
