ICESat-2 is a satellite mission under development by NASA for launch in 2015.  It will make measurements of ice sheet elevations in Antarctica over a 3-5 year period, to accurately the shape of the ice sheet, and to show how the ice sheet is changing over time.  As the satellite is developed, the science definition team, made up of researchers from NASA and from several different universities, provides direction as to what scientific questions the satellite measurements must address.  APL researcher Ben Smith has joined the team to investigate how best to tailor the measurements to the characteristics of ice…

Bonnie Light worked with collaborators at the Norwegian Polar Institute to measure light transmittance through first-year sea ice at Tempelfjord in Svalbard, Norway. Two graduate students from Atmospheric Sciences also participated in this effort under Dr. Light’s supervision in April 2011.

The APL family lost a dear friend and a key figure in our success in polar oceanography when Andy Heiberg passed away at home with his family on February 17, 2021 after short struggle with pancreatic cancer.

Andy was an internationally known expert in  operations and logistics for scientific fieldwork on sea ice. His career at the APL Polar Science Center began before PSC was part of APL and even before PSC was created…..

Southeast Greenland polar bear tagging by Kristin Laidre, late July-early August 2011.

Alan Thorndike died on Jan 8, 2018 from an aggressive pneumonia. He was 72 years old. For those of you who don’t know, Alan was one of the original AIDJEX gang and founding PIs of PSC. Working with Drew Rothrock, he developed the concept of the thickness distribution that is at the heart of most sea ice models.
