The ocean around Antarctica is changing in unexpected ways. Since 2015, sea ice surrounding the frozen continent has been ...

Researchers from the University of Murica (Murica, Spain), the Carlos III Health Institute (Madrid, Spain), and the University of Siena (Siena, Italy) evaluated the concentration of polychlorinated ...

Tiny ocean zooplankton play a massive role in trapping carbon deep below the surface, offering a hidden buffer against ...

Antarctic sea ice is more than just a platform for penguins. The sea ice's high reflectivity influences the whole Earth's ...

A new study has revealed that small but mighty zooplankton—including copepods, krill, and salps—are key players in the ...

Antarctic krill is a key species in the Antarctic marine ecosystem as an important food source for many species, such as whales, seals and penguins. However, the small crustaceans are increasingly ...

In search of krill, fishing vessels in the Southern Ocean encounter penguins during their main breeding season in the immediate vicinity of their breeding colonies. Antarctic krill is a key ...

Kim Bernard, at left, is an expert on Antarctic krill, a species crucial to the health of the continent’s food chain. For a research expedition on the Schmidt Ocean Institute’s R.V. Falkor ...

"In the late 1990s, we undertook a krill expedition, which was scientific. Now industries are ready," said Thamban Meloth, director, National Centre for Polar and Ocean Research.

A single Antarctic krill is about the size of your pinky finger. But with an estimated population of more than 700 trillion in the Southern Ocean, the tiny crustacean’s collective impact across ...

Krill larvae feed on algae that grows on the underside of frozen seawater floating near the ocean’s surface. “They graze on the sea ice like cows,” said Werner.

They multiplied this number by the rate at which krill produce carbon in their fecal pellets. This gave them the total amount of carbon held by krill in the upper ocean, which is about 20 meters deep.
