Gentoo penguin numbers actually increasing

Humpback whales in the oceans of the North Pacific, North Atlantic and Southern Hemisphere are much more distinct from each other than previously thought

On our journey north of the polar circle, my fellow adventurers and I were greeted by an astonishing spectacle. Over 20 orca were hunting an animal so rare that few people have seen them in the wild, let alone had the chance to study them. Using immense strength, agility and cunning intelligence, the orca worked as a team to hold the Arnoux’s beaked whale under water to drown it. This was a story of nature at its most raw, untouched and unforgiving—a story that encapsulated wild Antarctica.

Not all of the Southern Hemisphere humpback whales migrate towards the equator at the end of the Antarctic summer

Lake Vostok, the vast body of water hidden beneath the Antarctic ice sheet, has so far shown no signs of life.

South Georgia is the most well-known of the Falkland Islands, also called Islas Malvinas. It lies nearly at the end of the world in the Southern Atlantic Ocean. To find this place on the map, draw an equilateral triangle with one vertex on Cape Horn and another on the Antarctic Peninsula. The third vertex in the east is our destination.

Ultraviolet radiation has caused a steep increase in deaths among marine animals and plants, according to an international team including scientists at the Oceans Institute of The University of Western Australia.

A proposal to create a whale sanctuary in the southern Atlantic lacked "scientific backing", Japan said on Tuesday after leading the charge to scupper the plan at an international meeting.

Communities of species previously unknown to science have been discovered on the seafloor near Antarctica, clustered in the hot, dark environment surrounding hydrothermal vents.

On Christmas day the crew on board the Steve Irwin found the Japanese whaling factory ship by using a military-style drone.
