Scientists collect eDNA samples in the extreme environment of the Arctic melting glaciers autonomously

What if there was a way to collect environmental DNA (eDNA) samples in extreme environments autonomously? And what if this method allowed the collection of more samples and to prevent risk of sample contamination? Portuguese ...

Exploring a warm water inflow below an Antarctic ice shelf

The cold, dense water circulating under Antarctica's Filchner-Ronne Ice Shelf (FRIS) keeps under-ice melting there to a minimum, helping the ice shelf act as a regulating force against the Antarctic Ice Sheet's contribution ...

Off-axis high-temperature hydrothermal field discovered at the East Pacific Rise

Finding a new, high-temperature, off-axis hydrothermal vent field on the floor of the Pacific Ocean at 2,550 meters depth could change scientists' understanding of the impact that such ocean-floor vent systems have on the ...

First-of-its-kind research reveals rapid changes to the Arctic seafloor as submerged permafrost thaws

A new study from MBARI researchers and their collaborators is the first to document how the thawing of permafrost, submerged underwater at the edge of the Arctic Ocean, is affecting the seafloor. The study was published in ...

Exploration and evaluation of deep-sea mining sites

The seafloor near a mid-ocean ridge is often home to rising hydrothermal fluids from the deep crust that deposit minerals on the ocean bottom. These seafloor massive sulfide deposits offer new sources of copper, zinc, lead, ...

Vertical migration timing illuminates importance of predator pressure in the ocean's twilight zone

At dusk, millions of fishes, crustaceans, squids, and other animals leave the ocean's twilight zone and swim to the surface. At dawn, they return to deeper waters. New research by MBARI Senior Scientist Kelly Benoit-Bird ...

Navigating beneath the Arctic ice

There is a lot of activity beneath the vast, lonely expanses of ice and snow in the Arctic. Climate change has dramatically altered the layer of ice that covers much of the Arctic Ocean. Areas of water that used to be covered ...
