Atlas of polar seafloor unveiled

The most comprehensive and high-resolution atlas of the seafloor of both Polar Regions is presented this week (Tuesday 25 April) at the European Geosciences Union General Assembly (EGU) in Vienna. Over 250 marine geologists and glaciologists from around the world have spent the last four years collating stunning seafloor and glacial landform images to publish the new Atlas of Submarine Glacial Landforms. This new compilation enables researchers to interpret the history of the Earth’s large ice sheets and view how environmental change has re-shaped the continents.

Warm winds – new insight into what weakens Antarctic ice shelves

New research describes for the first time the role that warm, dry winds play in influencing the behaviour of Antarctic ice shelves. Presenting this week at a European conference scientists from British Antarctic Survey (BAS) explain how spring and summer winds, known as föhn winds, are prevalent on the Larsen C Ice Shelf, West Antarctica and creating melt pools. The Larsen C Ice Shelf is of particular interest to scientists because it of the collapse of Larsen A in 1995 and Larsen B in 2002.
