Mega-iceberg melt affects important marine ecosystem

Scientists have for the first time taken in-situ ocean measurements during the collapse of a giant iceberg in the sub-Antarctic. These new observations reveal how ocean ecosystems may be affected if more icebergs calve due ...

Antarctica is dedicated to peaceful scientific activity, but the security of research conducted there is in danger

When Tasmanian astronomer Louis Bernacchi set foot on Antarctica in 1898, he declared, "Antarctic exploration is of capital importance to science." While his statement remains as true as ever, scientific exploration has faced ...

Ice shelves fracture under weight of meltwater lakes, study shows

When air temperatures in Antarctica rise and glacier ice melts, water can pool on the surface of floating ice shelves, weighing them down and causing the ice to bend. Now, for the first time in the field, researchers have ...

Scientists count huge melts in many protective Antarctic ice shelves. Trillions of tons of ice lost.

Four dozen Antarctic ice shelves have shrunk by at least 30% since 1997 and 28 of those have lost more than half of their ice in that time, reports a new study that surveyed these crucial "gatekeepers'' between the frozen ...

Study explores supergiant iceberg's huge impact on surrounding ocean surface

The melting of the supergiant iceberg A-68 had a huge impact on the ocean around South Georgia, in sub-Antarctica, and significantly changed the Southern Ocean's temperature and saltiness, with potentially major consequences ...

New study finds early warning signs prior to 2002 Antarctic ice shelf collapse

In 2002, an area of ice about the size of Rhode Island dramatically broke away from Antarctica as the Larsen B ice shelf collapsed. A new study of the conditions that led to the collapse may reveal warning signs to watch ...

'Blue marble': How a half-century of climate change has altered the face of the Earth

In December 1972, NASA's final Apollo mission (Apollo 17) took the iconic "Blue Marble" photo of the whole Earth. Many, including science fiction writer Arthur C. Clarke, had expected that the sight of Earth from afar would ...
