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

Each year, humpback whales make their long trip from Antarctica up past Australia's coast. But the journey that once followed ancient paths has become a maze of man-made hazards. What'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 ...

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.

Rising temperatures are putting the future of Antarctic krill at risk. Numbering in the trillions and collectively weighing hundreds of millions of tonnes, Antarctic krill are among the most numerous ...

Southern Ocean whale populations are being threatened by human activity — a trend that could worsen global warming, Stanford researchers found in a study published in September. Researchers at ...
