A sea of ancient ice

Oases in Sea Ice Are Essential to Life in Antarctica

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.

March 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.

Whale Blow Microbiome

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.

Whale Biopsy Collection

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.

Why 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.

March of the penguins

New Zealand Geographic

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

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.
