New findings will help scientists predict climate change impact on frozen continent. A University of California, Irvine-led team of glaciologists has unveiled the most accurate portrait yet of the contours of the land beneath Antarctica ...
Apr 29, 2016 · New research provides the first look into the biogeochemistry, geophysics and geology of Subglacial Lake Whillans, which lies 800 meters (2,600 feet) beneath the West Antarctic Ice Sheet.
Dec 19, 2019 · Antarctica’s topography has gotten progressively lower over time: 34 million years ago, there was about 25% more land above sea level than there is today. ... Derouin, S. (2019), What lies ...
At 12,500 square kilometres and with an average depth of 430 metres, Lake Vostok is the world’s sixth-largest lake by volume, but as it lies beneath some 3.5km of ice, it’s not easy to visit.
Aug 6, 2019 · Antarctica is completely surrounded by an ocean, allowing sea ice to greatly expand in winter. Ice normally covers around 18 million square miles at the September maximum (its winter) and decreases to 3 million square miles during the February minimum (its summer). NASA's Earth Observatory has a nice side-by-side graphic comparing the maximum ...
Nov 9, 2018 · Knowing what lies beneath the ice sheet will help scientists understand its behavior and how the bedrock will respond as climate change begins melting the ice, causing the rock to rebound upward.
Jun 7, 2013 · Ice penetrating radar begins to show more and more detail of what lies below the Antarctic ice. Looking at close up images of the topography a researcher notices something that ‘just doesn’t ...
