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 ...

Sea monkeys (white) move in response to light, so researchers were able to make them "migrate" in their own lab. A high-speed camera captured the movement of water currents, shown in yellow in the ...

A new discovery reveals that the shrimp-like creature at the heart of the Antarctic food chain could play a key role in fertilizing the Southern Ocean with iron -- stimulating the growth of ...

Tiny krill are vital to ocean life. New research shows how these shrimp-like creatures adapt their feeding. By changing how they move their limbs, krill can cope with less food. This adaptability is ...

Shrimp-like krill can thrive in icy waters 9,800 feet (3,000 meters) deep off Antarctica as well as near the surface, according to a new study that shows krill stocks can survive far deeper than ...
