From the air, Greenland’s ice sheet looked like white molasses oozing
down the mountainside and into the sea. Researchers are investigating Greenland’s glacial lakes, which form atop the
ice […]

In Antarctica, fierce winds blow plumes of snow out to sea and erase most of the 400 mile long Ross Ice Shelf from view. As global climate warms, […]

Emperor penguin chicks hatch into the frozen world of Antarctica—one of Earth’s most inhospitable places. A recent study reveals what the juveniles do in the critical early months […]

This image of a blue iceberg, calved off a glacier, was captured on a research trip to waters off Greenland. Its striking color indicates that the ice in it is […]

Summertime ice melt along the Greenland Ice Sheet has sped up in recent decades, more fresh water to flow into the surrounding ocean. The fresh water carries nutrients and […]

A large iceberg breaks away from the Helheim Glacier and floats among slabs of pack ice in Sermilik Fjord along the southeastern coast of Greenland. The glacier, about 3 […]

Tuktoyaktuk means “Land of the Caribou” in the Inuvialuit language, which explains the sculpture in the foreground, but the landscape of the Northwest Territories, Canada, is also of interest for […]

WHOI physical oceanographer Robert Pickart is currently leading an international team on board the NATO research vessel Alliance to get a close-up look at a poorly understood, but critical, […]

The North Atlantic can be an inhospitable place, especially in late winter, but that is exactly when WHOI physical oceanographer Robert Pickart needs to be there. Pickart and his […]

In 2012, 98 percent of the Greenland Ice Sheet‘s surface area melted for several days, sending torrents of meltwater down glaciers near the coast. Rising meltwaters and icebergs also […]

Clearing ice from the decks of the U.S. Coast Guard icebreaker Healy was a regular task for ship’s crew during a 2011 cruise into the Arctic. WHOI biologist Read More

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 […]

An ice-tethered profiler (ITP) takes one last look at the sky before passing through four meters of ice in the Beaufort Sea to begin a study of ocean physics, […]

Sea level rise is accelerating as warming temperatures cause ice to melt and ocean water to expand. Under many scenarios, sea level rise is expected to remain under three […]

Guest investigator Kristina Brown, right, and research assistant Kate Morkeski troubleshoot a new dissolved inorganic carbon sensor in the lab of WHOI marine chemist Aleck Wang. In the Arctic, […]

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 […]
