Ice sheet deglaciation and methane emissions, with the scope on Greenland’s melt season

On June 9 2016, Nuuk, the capital of Greenland, reached the warmest temperature ever recorded for the month of June anywhere on the island, 24 degrees Celsius (75 degrees Fahrenheit). An article from NSDIC, published June 22 elaborated on the broader situation: Surface melting on Greenland’s Ice Sheet proceeded at a brisk pace, with three…

AGU 2015: Eric Rignot – Ice Sheet Systems and Sea Level Change

Scientific Discipline Cryosphere Speaker Eric Rignot (NASA Jet Propulsion Laboratory) Abstract Modern views of ice sheets provided by satellites, airborne surveys, in situ data and paleoclimate records while transformative of glaciology have not fundamentally changed concerns about ice sheet stability and collapse that emerged in the 1970’s. Motivated by the desire to learn more about…

AGU 2015: Alaska’s thawing permafrost Latest results and future projections

Alaska’s permafrost is starting to thaw as the climate warms, and scientists project there will be even greater thawing of the frozen soils in the coming decades, releasing carbon into the atmosphere, and impacting ecological systems and infrastructure. A panel of permafrost experts will unveil new findings about permafrost degradation in Alaska, where permafrost covers…

Remote Antarctic Trek Reveals A Glacier Melting From Below

September 15, 2013 by Richard Harris from NPR – Scientists watching Antarctica’s Pine Island Glacier from space have noticed with some alarm that it has been surging toward the sea. If it were to melt entirely, global sea levels would rise by several feet. Source NPR (with transcript) Related New Antarctic ice core reveals secrets…

Video: What Lies Beneath: NASA Antarctic Sub Goes Subglacial NASA / JPL February 28, 2013: When researcher Alberto Behar from NASA’s Jet Propulsion Laboratory in Pasadena, Calif., joined an international Antarctic expedition last month on a trek to investigate a subglacial lake, he brought with him a unique instrument designed and funded by NASA to help…

Glacier hydrology an introduction

By Bethan Davies / AntarcticGlaciers.org Introduction | Supraglacial hydrology | Englacial hydrology | Subglacial hydrology | Proglacial drainage | References Introduction Glacier hydrology is the study of the flow of water through glaciers. It is a mysterious world, where water running on the surface of the glacier disappears through cracks and holes in the glaciers,…
