Hundreds of thousands of years ago, the area was a massive polar ice sheet, with walls of ice kilometres high, where woolly mammoth and strait-tusked elephants wandered with sabre-toothed cats, bison and giant short-faced bears.
The humidity released by the resulting thermal contrast, which was presumably carried northwards by wind, caused the snowfall that formed the polar ice sheet, the researchers believe.
It details the historical and current context and what it accomplished; the human element, including training young scientists, increasing diversity, engaging polar residents and building community capacity, communicating with the public, and providing resources for teachers; advances and discoveries relating to polar ice sheet science and subglacial systems, sea ice vulnerability and connections to society, marine ecosystems and global warming, polar atmospheric observations and lower latitude impacts, geospace and space weather, terrestrial earth systems and permafrost, evidence of past climate change, human health, and other areas; the impact of IPY on tools used for polar research; and the need to translate scientific knowledge into actionable information.
Dr David Vaughan from the British Antarctic Survey will discuss difficulties involved in estimating the contribution of polar ice sheet melting to sea level rise.
Sheet Mass Balance Inter-comparison Exercise (IMBIE) -- that combined observations from 10 satellite missions to develop the first consistent measurement of polar ice sheet changes.
The study combined observations from 10 different satellite missions to develop the first consistent measure of polar ice sheet changes.
Because of the land mass sitting beneath it, the polar ice sheet can rise as high as four kilometres above sea level, providing a good gradient for the dense air to flow down on its way to the ocean.
His work examining sediment cores from Antarctica's seafloor indicates if the planet were two to three degrees warmer, it would have a dramatic effect on the polar ice sheet.
The ICESat-2 mission to measure polar ice sheets, which the 2007 survey recommended launching between 2010 and 2013, is now slated to go up in September.
The Last Interglacial was marked by higher temperatures, which led to melting of glaciers and polar ice sheets, raising sea levels.
Christina is conducting research on the Polar Ice sheets, on the changes that have occurred in the past and those that are happening now.
Otherwise, sea levels may rise more than a meter by 2100 and more if polar ice sheets collapse.
