Deep channels link ocean to Antarctic glacier

Newly discovered deep seabed channels beneath Thwaites Glacier in West Antarctica may be the pathway for warm ocean water to melt the underside of the ice. Data from two research missions, using aircraft and ship, are helping ...

Scientists discover new penguin colonies from space

A new study using satellite mapping technology reveals there are nearly 20% more emperor penguin colonies in Antarctica than was previously thought. The results provide an important benchmark for monitoring the impact of ...

Antarctic sea ice loss explained in new study

Scientists have discovered that summer sea ice in the Weddell Sea area of Antarctica has decreased by one million square kilometres—an area twice the size of Spain—in the last five years, with implications for the marine ...

Antarctic sea-ice models improve for the next IPCC report

The world of climate modeling is complex, requiring an enormous amount of coordination and collaboration to produce. Models feed on mountains of different inputs to run simulations of what a future world might look like, ...

Benthos in the Antarctic Weddell Sea in decline

Over the past quarter-century, changes in Antarctic sea-ice cover have had profound impacts on life on the ocean floor. As biologists from the Alfred Wegener Institute report in the latest issue of the journal Nature Communications, ...
