David Needham One of our goals today was to find and sample a large phytoplankton bloom to study phytoplankton and bacterial associations. Although blooms often occur in the spring, they can be hard to predict, and the ocean doesn’t give its secrets away easily! Fortunately, we identified a large bloom using observations from satellite chlorophyll …

David Needham The first day and a half of our cruise was busy and exciting. After an initial delay of six hours due to rough seas and strong winds, we had a successful deployment of the ROV Doc Ricketts aboard the R/V Western Flyer. With the help of the robotic arms of the ROV and the …

An acidic ocean has been shown to affect many species, but the impacts on entire communities are more complicated.

MBARI’s newly printed 2016 Annual Report is filled with ocean-research adventures and discoveries. It is available now as a PDF file on MBARI’s website.

The importance of eDNA Meilina Dalit Today we repeated yesterday’s activities of coordinating simultaneous sampling from the R/V Western Flyer (CTD casts), the Reuben Lasker (midwater trawls), and LRAUV Aku (Environmental Sample Processor sampling). While LRAUV Aku is autonomously collecting samples with a third-generation Environmental Sample Processor (ESP), Research Specialist Kevan Yamahara is also archiving …

New partnerships and technologies add an exciting new dimension to MBARI's 2017 CANON experiment.

Meeting the Reuben Lasker Meilina Dalit This is an expedition with many moving parts, and today we added the R/V Reuben Lasker, a NOAA ship, into the mix. We rendezvoused with the ship at an offshore upwelling front (the boundary between cold, nutrient-rich upwelled water and warmer offshore water) that was identified by our fleet …

New laser technology is allowing MBARI scientists to look into the structure of giant larvaceans--tadpole-like marine animals that are important players in ocean ecosystems.

Using sound to locate prey Meilina Dalit Despite the early call time of 4:30 a.m., spirits were pleasant the morning of the first day of the expedition. With a great weather forecast for the next couple of days, there was little to complain about other than wishing for another hour of sleep. The R/V Western …

In the first quantitative analysis of deep-sea bioluminescence, MBARI researchers Séverine Martini and Steve Haddock show that three quarters of the animals in Monterey Bay from the surface down to 4,000 meters deep can produce their own light.

MBARI’s M1 mooring is an important data collection station that floats above the seafloor in Monterey Bay continuously taking a variety of measurements to give researchers a clear picture of oceanographic conditions.

A new paper reveals the first observations of an elusive, giant pelagic octopus with a surprising choice of prey: jellyfish!

A team effort Nancy Barr The work completed this week will be very helpful for Scientist Charlie Paull as he plans his Western Flyer expedition scheduled for next month. Paull’s team will be collecting instruments placed in the canyon for the Coordinated Canyon Experiment, and will collect samples at key locations in the canyon. The …

Seeing fine details in the deep sea Nancy Barr Images created from two days of surveying an extensive clam field in Monterey Canyon are impressive for their level of detail—especially when you remember that these pictures are coming from more than 2,800 meters deep (about 1.7 miles) in the ocean. The surveys answered some science …

MBARI’s remotely operated vehicle (ROV) Ventana completed its 4,000th dive in February 2017. With over 16,000 hours underwater, Ventana is by far the most experienced scientific ROV in the world.

Clams as far as they can see Nancy Barr When the ROV Doc Ricketts arrived at an extensive clam bed deep in Monterey Canyon this morning, it was soon evident that things had not changed drastically since the last time the site was mapped by David Caress and his team. That answered the first question …

Taking in the big picture Nancy Barr While it has long been possible to capture video and still images in the deep sea, most cameras used at depth have a very limited field of view and—unless the water is perfectly clear—must be very close to their subject matter. The stereo cameras used in this week’s …

The first survey Nancy Barr The first low-altitude survey of this expedition centered on an area surrounding an instrument node located about 30 kilometers offshore at a depth of 1,850 meters in Monterey Canyon. Here’s how it works: Four systems record data as the ROV runs a preprogrammed path across a 100-meter-square section of the …

Annette Gough joined MBARI as an administrator in 1988 (the institute was established in 1987) and is retiring this year.

The US Strategic Environmental Research and Development Program recently selected one of Kelly Benoit-Bird’s research as its Resource Conservation and Climate Change Project of the Year.
