Greenland Aquifer Team Blog

Greenland Aquifer Team

Glaciologist Lora Koenig is leading an expedition to southeast Greenland in April to investigate an aquifer trapped within the ice sheet. The team, which includes lab member Ludovic Brucker, will drill several holes in the ice sheet to analyze snow density and structure. They will also leave instrumentation in the drilled holes to record temperatures over a year.

Google + Hangout on Sea Level Rise

The Hangout

Ice sheet modeler Sophie Nowicki participated in a Google + Hangout on sea level rise with three other scientists from NASA’s Jet Propulsion Laboratory and the U.S. Geological Survey on April 2. The hour-long Hangout, which covered topics ranging from uncertainties in sea level rise modeling to potential impacts on coastal communities, was the kick-off event for NASA’s Earth Month celebrations.

2013 Artic Sea Ice Maximum is 5th Lowest on Record

Sea Ice Maximum

A NASA analysis led by Joey Comiso determined that the annual maximum Arctic sea ice extent was reached on Feb. 28 and it was the fifth lowest sea ice winter extent in the past 35 years. The new maximum —5.82 million square miles (15.09 million square kilometers)— is in line with a continuing trend in declining winter Arctic sea ice extent: nine of the ten smallest recorded maximums have occurred during the last decade. The 2013 winter extent is 144,402 square miles (374,000 square kilometers) below the average annual maximum extent for the last three decades.
