Science Summary:
In collaboration with DTU and UT, researchers will deploy two iAWS (Automated Weather Station) on the north-east ice stream, Greenland, within 50 km of the ice front of Zachariae Isstrom to document surface mass balance processes and changes in ice dynamics in a marine-based glaciological settings that is undergoing significant changes at present. The iAWS will provide surface climatology data and GPS data with a direct satellite uplink. The data will be analyzed to better understand why current regional atmospheric climate models do not capture surface melt processes quite accurately in the northeast in contrast to other parts of Greenland and to document short-term (hourly) changes in ice dynamics in response to the collapse of the Zachariae Isstrom ice shelf around 2012. The results will in turn help researchers better understand the evolution of this marine-based sector of Greenland and projects its future contribution to sea level rise. As part of this collaboration, DTU will deploy GPS stations at locations further upstream to document changes in glacier dynamics in the interior and share data access with our team. These data will document how far inland changes in ice dynamics are tracked down and on what time scales.

Logistics Summary:
In collaboration with DTU, NASA will deploy two iAWS (Automated Weather Station) on the north-east ice stream, Greenland, within 50 km of the ice front of Zachariae Isstrom to document surface mass balance processes and changes in ice dynamics in a marine-based glaciological settings that is undergoing significant changes at present. In 2016 a field team of two will install the iAWS via Air Greenland helicopter in early August. Station AWS3 will be deployed by Konrad Steffen during the Spring 2016 season.

CPS will provide requisition/procurement support in supplementing the DTU helicopter charter with NASA funds. All other logistics will be arranged and paid for by the PI or his collaborators.
