Carin Ashjian, a senior scientist at WHOI, was one of 97 scientists and crew members aboard a German oceanographic research vessel that has been deliberately stranded in Arctic Sea ice as part of the year-long MOSAIC experiment.
Study Finds New Source of Trace Elements Could Rapidly Change Arctic Ecosystems
A new study by WHOI and their international colleagues found that freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean via the Transpolar Drift—a major surface current that moves water from Siberia across the North Pole to the North Atlantic Ocean.
Imagining Home: scientist’s stay in the Arctic extended by coronavirus
WHOI biologist Carin Ashjian is aboard the icebreaker Polarstern in the Arctic as part of the year-long MOSAiC research expedition. She should be almost home by now. Instead, her stay has been extended by COVID19.

A polar bear sighting off the U.S. Coast Guard Cutter Healy during the 2015 Arctic GEOTRACES expedition. The Arctic has experienced the highest degree of warming on the planet, causing sea ice to thin and recede. The region’s iconic polar bears rely on sea ice to hunt, travel and mate.

This video explains the key physical, biological and ecological processes in oases on the Antarctic icy coast — polynyas. Researchers at Woods Hole Oceanographic Institution and the University of Delaware are trying to unveil crucial connections among the physical and biological components in the polynyas and to understand how the Antarctic ecosystem responds to changes in the large-scale environment.

Read MoreMarch of the Penguins
Emperor penguins are some of the most striking and charismatic animals on Earth, but a new study from the Woods Hole Oceanographic Institution (WHOI) has found that a warming climate may render them extinct by the end of this century. The study, which was part of an international collaboration between scientists, published Nov. 7, 2019, in the journal Global Change Biology.
The fate of the penguins is largely tied to the fate of sea ice, which the animals use as a home base for breeding, feeding and molting, she notes. Emperor penguins tend to build their colonies on ice with extremely specific conditions—it must be locked into the shoreline of the Antarctic continent, but close enough to open seawater to give the birds access to food for themselves and their young. As climate warms, however, that sea ice will gradually disappear, robbing the birds of their habitat, food sources, and ability to raise their chicks.
Jenouvrier and her team conducted the study by combining two existing computer models. The first, a global climate model created by the National Center for Atmospheric Research (NCAR), offered projections of where and when sea ice would form under different climate scenarios. The second, a model of the penguin population itself, calculated how colonies might react to changes in that ice habitat.

Researchers from WHOI, NOAA Fisheries Southwest Science Center, SR3 Sealife, and the Vancouver Aquarium analyzed whale blow samples collected via drone to identify a core group of bacteria in the respiratory tract of healthy whales.

A team gathers skin samples from healthy humpback whales in waters off the Western Antarctic Peninsula. Researchers obtain samples by releasing a biopsy-collecting dart, which bounces off the whales’ skin and into the water. The team then retrieves the floating dart and brings it back to a lab for analysis.
Read MoreWhy is the Greenland Ice Sheet melting faster than ever?
Senior scientist Claudia Cenedese has been studying how glaciers melt for the last 15 years in her fluids laboratory. In 2018 she was a principal investigator on a research cruise in Greenland for the first time. She wants to understand why the Greenland Ice Sheet is melting faster than ever and what happens to the fresh water released into the ocean.

Read MoreMarch of the penguins
If current warming trends continue, emperor penguins will be marching toward an 86 per cent population decline by the end of the century, at which point, “it is very unlikely for them to bounce back,” says study author Stephanie Jenouvrier, a seabird ecologist from Woods Hole Oceanographic Institution.
Nereid Under Ice explores Aurora hydrothermal vent field
The newly upgraded Nereid Under Ice, a hybrid remotely operated vehicle, is deployed from the Norwegian Icebreaker KronPrins Haakon to conduct its first deep ocean dives to 4,000 meters (over 13,000 feet) along the Gakkel Ridge in the Arctic Ocean.

Emperor penguins are some of the most striking and charismatic animals on Earth, but a new study from the Woods Hole Oceanographic Institution has found that a warming climate may render them extinct by the end of this century.

It’s the coldest environment on Earth, with a mean temperature of minus-76 in winter and minus-18 in summer, according to the Woods Hole Oceanographic Institution.
Breaking Ice: Science at the Top of the World
Since 2003, the Beaufort Gyre Exploration Project at the Woods Hole Oceanographic Institution has given us an up-close look at one of the fastest-changing parts of the world. In 2018, the Ocean Media Institute at Montana State University sent Hugo Sindelar to join the annual expedition aboard the Canadian icebreaker Louis S. St. Laurent to see how the scientists and engineers involved in the project bring back their hard-earned data and to hear what they’ve learned so far.
