The Canadian icebreaker Louis S. St-Laurent negotiates thick ice floes near Beaufort Gyre, a major Artic Ocean circulation system north of Alaska. Global warming may be disrupting the […]

This oceanographic tool— a Van Veen grab sampler—collects seafloor sediments. It’s probably not the first thing you might expect to find on a research cruise led by a physical […]

WHOI engineer Brian Hogue assembles a new aluminum frame around a Nobska MAVS-4 acoustic current meter. The frame helps to minimize turbulence around the current meter once it is […]

WHOI engineers led by Lee Freitag have developed and tested a long-distance communications system that would transmit and receive signals under Arctic Ocean sea ice. They exploited a […]

The ocean’s global circulation transports heat around the planet, from the equator to the poles, thus regulating Earth’s climate. Two major cogs in this planetary system are the Gulf […]

This year marked the tenth year of the Beaufort Gyre Exploration Project led by WHOI physical oceanographer Andrey Proshutinsky and Richard Krishfield. Funded by the National Science […]

Simulated models of how plastics are transported in the global ocean show that most plastics concentrate in the middle of subtropical gyres (left). However, large-scale ocean circulation systems such […]

In 2013, a WHOI-led research team set sail for the Eastern Beaufort Sea. Their mission: to search for evidence of a huge, ancient, freshwater flood caused by the melting of […]

The U.S. Coast Guard icebreaker Healy steams through “pancake” sea ice in the Arctic Ocean in October 2013. WHOI physical oceanographer Bob Pickart led the cruise to complete […]

The bow of the U.S. Coast Guard icebreaker Healy plows a path through sea ice in the Beaufort Sea. Evidence of Earth’s changing climate is especially visible in the […]

A lone buoy sits atop Arctic sea ice in the Canadian Basin—a yellow dot in a vast field of white. Suspended in the water below the buoy, a beacon sends […]

Twin Otter planes are packed full of buoys, cables, and other equipment for flights from Banks Island north of Canada onto the Arctic Ocean ice pack. The planes carry 2,000 […]

During the austral summer of 2016, WHOI scientists Viviane Menezes and Alison Macdonald traveled to Antarctica to study a physical ocean process known as Antarctic Bottom Water […]

Photographed in a drop of water, this shrimp-like crustacean is tiny—about the size of a fingernail. It comes from Barrow Canyon, a seafloor feature in the Arctic Ocean that’s […]

WHOI researchers Kris Newhall (left) and Rick Krishfield (right), and Brian Mackenzie, crew member of the Canadian Coast Guard icebreaker Louis S. St-Laurent, set up an ice-tethered profiler […]

Scientists drill a hole through meter-thick sea ice to collect water samples in the Arctic Ocean. MIT-WHOI Joint Program graduate student Lauren Kipp was among scientists from several […]

Data from the ice-covered Arctic Ocean are hard to come by because the region is extremely remote and the environment hostile. Scientists and engineers are overcoming these challenges by deploying […]

WHOI engineer Marshall Swartz (right) instructs Louis Clement, a post-doctoral scientist at the Lamont-Doherty Earth Observatory, on the technical intricacies of a CTD rosette equipped with a lowered acoustic doppler current profiler (ADCP). […]

A special, thick-walled tank permits guest investigator Sheng-Qi Zhou from the South China Sea Institute of Oceanology in Guangzhou, China, to observe mixing processes under the pressures experienced deep in the […]
