 Carrying Fieldwork and Blogging From Antarctica

Ice sheet modelers Ryan Walker and Christine Dow are spending a month at the Jang Bogo station in Terra Nova Bay, Antarctica, to measure flexure of ice tongues due to ocean tides. The researchers are installing five GPS stations on floating sections of the Nansen Ice Shelf, to record uplift of the ice, plus two tilt sensors at the grounding line to measure subtle changes in ice uplift and motion.

 IceBridge Flies Parallel Campaigns At Both Poles

For the first time in its seven years of flights, NASA's Operation IceBridge, an airborne survey of changes in Earth’s polar ice, is conducting overlapping campaigns in Antarctica and the Arctic. Since 2009, IceBridge has studied Antarctic ice conditions each fall, but this year a new field campaign has been added to collect measurements of sea and land ice in the Arctic to provide insight into the impact of the summer melt season.
The Antarctic campaign was the first to kick off on Sept. 22, as IceBridge successfully completed its first research flight over the southernmost continent. Antarctic flights continue until Nov. 2. The first flight of the Arctic campaign was on  Sept. 23, with ongoing flights until Oct. 23.

 SIMPL Field Campaign in Greenland

The Ice, Cloud and land Elevation Satellite-2 (ICESat-2) mission flew a laser altimeter instrument aboard an aircraft over Greenland for three weeks in August. The instrument, called the Slope Imaging Multi-polarization Photon-counting Lidar, or SIMPL, took height measurements with both a red and a green laser, which will allow scientists to determine whether green light behaves differently when it reflects off different types of snow and ice.
The Greenland SIMPL campaign is part of a multi-year, pre-launch effort to find out as much as possible about how lasers and photon detectors similar to those on ICESat-2 measure ice sheet height, and what that photon data looks like.

 Laboratory Participates In 2015 Science Jamboree

A dozen members of the Cryospheric Sciences Laboratory participated in the 2015 Science Jamboree's, Goddard's yearly outreach event that bring together displays and demonstrations from all of the center's science divisions.
The laboratory's booth, which received visits from Chris Scolese, Goddard Center Director (pictured), Colleen Hartman, Science and Exploration Directorate (SED) Director and SED Deputy Director Piers Sellers, featured an over 200-year-old ice core from Greenland, a demonstration of glacier dynamics and models of the aircraft that Operation IceBridge uses in its Arctic and Antarctic campaigns. Member of the lab discussed cryospheric research with a constant stream of summer interns, day visitors and researchers from other laboratories, and handed out outreach materials on ICESat-2, Operation IceBridge and sea ice.
