MBARI is embarking on a new chapter in its ocean research with the construction of a state-of-the-art ship named in honor of MBARI's founder.

Using advanced echosounders, MBARI researchers are measuring the distribution, abundance, type, size, and movement of predators and their prey in the deep sea.

MBARI oceanographer John Ryan and his colleagues discovered that whale sharks swim across the Eastern Tropical Pacific following fronts—dynamic boundaries between warm and cold ocean waters.

A new paper by MBARI researchers shows that filter-feeding animals called giant larvaceans can collect and consume microplastic particles, potentially carrying microplastics to the deep seafloor.

Despite their close proximity, two recently discovered hydrothermal vent fields in the Gulf of California host very different animal communities. This finding contradicts a common scientific assumption that neighboring vents will share similar animal communities.

Throughout the world ocean, animals congregate at certain depths. A new paper in Limnology and Oceanography shows that, rather than consisting of a random mixture of animals, these deep-scattering layers contain discrete groups of squids, fishes, and crustaceans.

In the spring of 2015, Monterey Bay experienced one of the most toxic algal blooms ever. A new paper shows that this bloom became particularly toxic because of an unusually low ratio of silicate to nitrate in Bay Waters.

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.

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.

Axial Seamount, a large underwater volcano off of the Oregon coast, is one of the most active volcanoes in the world, having last erupted in 2015. At the Fall 2016 meeting of the American Geophysical Union, MBARI researchers unveiled a new seafloor map that reveals previously undocumented lava flows from the 2015 eruption.

The National Oceanic and Atmospheric Administration recently approved a five-year, $11 million grant to the Central and Northern California Ocean Observing System (CeNCOOS). On December 5-6, 2016, CeNCOOS will hold its annual meeting to discuss recent discoveries and future plans for monitoring the coast using funds from their new federal grant.

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.

Researchers at MBARI have learned a lot about Monterey Bay using robotic submersibles to look deep below the bay’s surface. Now they can listen to the bay as well, using an ultra-sensitive underwater microphone.

In spring 2015, MBARI researchers discovered a large, previously unknown field of hydrothermal vents in the Gulf of California, about 150 kilometers (100 miles) east of La Paz, Mexico.

Exploring the deep sea, and especially submarine canyons, is a risky business. The floors of many submarine canyons are scoured by fast-moving underwater avalanches known as "turbidity currents."

Over one thousand miles wide and three thousand miles long, the Sargasso Sea occupies almost two thirds of the North Atlantic Ocean. Within the sea, circling ocean currents accumulate mats of Sargassum seaweed that shelter a surprising variety of fishes, snails, crabs, and other small animals.

Researchers at the Monterey Bay Aquarium Research Institute (MBARI) have observed a deep-sea octopus brooding its eggs for four and one half years—longer than any other known animal.

From the vampire squid to the flapjack octopus, deep-sea cephalopods come in an amazing variety of shapes and sizes. Yet few humans have seen these animals alive. Since April, members of the public have been able to see these animals for the first time, as part of the ongoing Tentacles special exhibition at the Monterey Bay Aquarium.

Thousands of shipping containers are lost from cargo vessels each year. Many of these containers eventually sink to the deep seafloor. In 2004, scientists at MBARI discovered a lost shipping container almost 1,300 meters (4,200 feet) below the surface of the Monterey Bay National Marine Sanctuary.

Killer sponges sound like creatures from a B-grade horror movie. In fact, they thrive in the lightless depths of the deep sea. Scientists first discovered that some sponges are carnivorous about 20 years ago. Since then only seven carnivorous species have been found in all of the northeastern Pacific.
