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.Read More
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.Read More
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 More
August 2019: Woods Hole Sea Grant has teamed up with Earthwatch Institute on the Girls in Science Fellowship. This fellowship aims to promote diversity and expose young women to a variety of marine careers in STEM. Woods Hole Oceanographic Institution Research Specialist Laela Sayigh is the principal investigator working with the fellows analyzing marine mammal bioacoustics data.Read More
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 More
Former WHOI Joint Program graduate student and current University of Washington postdoc Camrin Braun and his team on the charter fishing vessel Machaca managed to tag two porbeagles, a relative of the goblin shark, about 30 miles east of Chatham, Mass. One was a female nearly seven feet long and weighing 270 pounds. A male came alongside the boat while the team was tagging her and, when they were finished, they quickly hooked the curious male, which measured 6.5 feet and weighed 230 pounds.
Both fish are now equipped with fin-mounted SPOT satellite tags, which will report their location each time they surface and can last up to five years. For the Ocean Twilight Zone team, the big predators are an important indicator of where mesopelagic animals are collecting deep below the surface. In short, the predator will go where the prey is.Read More
This bejeweled beauty is a strawberry squid (Histioteuthis reversa), sampled from the ocean twilight zone, a mysterious stratum of the ocean between the sunlit surface layer and extending down to about 1,000 meters (3,300 feet) deep.Read More

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.Read More
Jellyfish have lived on earth more than 600 million years, and boast a diverse evolutionary history. Most jellyfish species live in the Twilight Zone. Little is known about this ocean region since it is vastly unexplored, but Woods Hole Oceanographic Institution is on a mission to change that. With their new Mesobot, the institution plans to study the Twilight Zone and the creatures that call it home.Read More
October 15, 2019 – Watch this recorded public event entitled Microplastics in the Ocean: Emergency of Exaggeration? with a keynote presentation by Dr. Kara Lavender Law on the science of ocean plastic pollution and laying the foundation for solutions.
Dr. Law is a faculty member at Sea Education Association, where she studies the distribution of plastic marine debris driven by ocean physics and the degradation and ultimate fate of plastics in the ocean.
Keynote presentation is followed by a panel discussion on the international perspectives on marine microplastics research moderated by Dr. Heather Goldstone, host of Living Lab, WCAI, Cape & Islands NPR. Panelists include:
Dr. Chelsea Rochman
University of Toronto, Canada
Dr. Hauke Kite-Powell
Woods Hole Oceanographic Institution, U.S.A.
Dr. Gunnar Gerdts
Alfred Wegener Institute, Germany
Dr. Hideshige Takada
Tokyo University of Agriculture and Technology, Japan
Dr. Collin Ward

A formation of four mola mola (ocean sunfish) paraded through the water past the starboard side of #RVNeilArmstrong last week, while mooring operations continued on the Ocean Observatories Initiative Pioneer Array, 130 miles southeast of Martha’s Vineyard. These giant omnivores are the largest bony fish (Osteichthyes) in the ocean, measuring up to 11 feet in height and weighing up to 2.5 tons. They get their common name from the fact that they can be sometimes be found turned sideways on the ocean surface basking in the sun. Leo Fitz, who has crewed on WHOI ships for decades said he’s never been so fortunate to see so many at once: ‘Never, it’s always one! Never THIS many!”Read More
