Two new research projects – in partnership with British Antarctic Survey engineers – will drill deeper than ever before in Antarctica and in space. The first project, called INCISED, is led by the University of Durham, funded by the European Research Council, and has set its sights on the Antarctic. It will drill bedrock from beneath the polar ice sheets, with the goal being to retrieve scientific samples.
Pine Island Glacier (PIG), the longest and fastest flowing glacier in the Antarctic, has spawned a huge iceberg. The block measures about 720 sq km in area - roughly eight times the size of Manhattan Island in New York.
Nearly two dozen research teams collaborated to study polar ice sheets in Greenland and Antarctica and discovered definitively that they have added 11mm to global sea levels since 1992, melting ever more quickly.
Greenland's massive ice sheet has melted this month over an usually large area, Nasa has said. Scientists said the unprecedented melting took place over a larger area that ever detected in three decades of satellite observation.
The Times Atlas of the World exaggerated the rate of Greenland's ice loss in its thirteenth edition last week, scientists said on Monday.
Ice loss from Antarctica and Greenland has accelerated over the last 20 years, research shows, and will soon become the biggest driver of sea level rise. From satellite data and climate models, scientists calculate that the two polar ice sheets are losing enough ice to raise sea levels by 1.3mm each year.
