Marine biologists describe three new species of predatory sponges that live in the depths off California and Baja California.

The institute opened its doors to the public, providing visitors with a once-a-year opportunity to talk with scientists, engineers, and marine operations crews about their work.

MBARI's Environmental Sample Processors (ESPs), originally designed to study toxic algal blooms in the ocean, are now being used to protect municipal drinking-water supplies.

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.

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

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

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.

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.

New research findings highlight a unique visual adaptation in a deep-sea squid, the cockeyed squid, which has eyes that are grossly different in size and structure.

A new paper in the journal PLOS One shows that some species of juvenile rockfish find it harder to exert themselves in acidified seawater, but other species are more adaptable.

MBARI’s Benthic Rover, an autonomous seafloor crawler, recently broke it's own world record, spending over a year autonomously crawling across the deep seafloor and collecting scientific data without any help from humans.

A century after its first discovery, the existence of the giant larvacean, B. charon, was confirmed by MBARI scientists when a routine sample collection turned extraordinary.

A new MBARI robot will add to the midwater observations researchers have been making with remotely operated vehicles (ROVs) for nearly two decades.

An unusual deep-sea fish that was previously identified in the Southeastern Pacific has recently been found to live around the Hawaiian Islands and off the coast of Central California as well.

A recent paper shows that some juvenile king crabs hitch rides on wandering sea cucumbers, perhaps as a way of evading predators.

MBARI’s newest senior scientist, Kelly Benoit-Bird, uses sound to observe animals such as seabirds and dolphins as they chase their prey underwater.

MBARI Postdoctoral Fellow Anela Choy, who studies the impacts of plastic debris on ocean food webs, has been selected as one of five recipients of the L'Oreal Women in Science Fellowship for 2016.

What happens when you merge dance and science? SpectorDance and MBARI have done it again with Ocean Trilogy.

MBARI Adjunct Victoria Orphan has been named a 2016 MacArthur Fellow, in recognition of her work on microbial communities in extreme environments and their impact on the cycling of nutrients and energy through the oceans.
