Walter Munk was a giant in the world of oceanography. He died February 8, 2019 at his home in La Jolla, California.

A new study shows that anchovies and krill in Monterey Bay form dense aggregations during upwelling events caused by strong northwest winds.

Beaked whales congregate in parts of a Navy sonar test range off Southern California that have dense patches of deep-sea squid that are lacking in nearby “sonar-free” areas.

Marine biologists recently discovered large schools of fishes thriving in low-oxygen conditions that would be deadly to most other fish.

Peter Brewer receives the prestigious National Science and Technology Award in Beijing, China.

In 1995, an oil-field work boat sank suddenly off Southern California. Twenty-three years later, an MBARI ROV pilot who worked on that boat helped find the wreck.

Ocean researchers propose a new "pole-to-pole" Marine Biodiversity Observation Network

Marine biologists recently discovered five new species of colorful nudibranchs on the deep seafloor offshore of California and Baja California.

Adopt-A-Float program lets grade-school students participate in a major scientific study of the vast Southern Ocean.

Pulses of sinking debris carry large amounts of carbon to the deep seafloor, but are poorly represented in global climate models.

Deep in the Gulf of California MBARI researchers watched shrimp "play dead" by hanging motionless in the water. They speculate that the shrimp do this to avoid being eaten.

Scientists know that the ocean is taking up a lot of carbon dioxide from the atmosphere. Marine chemist Andrea Fassbender is bringing this process into focus by studying how carbon moves between the atmosphere, upper ocean, and deep sea.

Oceangoing robots are taking on ever-more complicated tasks and ushering in a technology revolution in oceanography, transforming the everyday work of ocean researchers.

Building on their 2015 expedition, MBARI researchers will be mapping the Pescadero Basin and searching for hydrothermal vents.

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

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.

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.
