OMG will use NASA's G-III to fly the Glacier and Ice Surface Topography Interferometer (GLISTIN) in order to generate high resolution, high precision elevation measurements of Greenland's coastal glaciers during the spring. Annual surveys by GLISTIN will measure glacier thinning and retreat over the preceding season. A second aircraft campaign will be occur each year in the summer to deploy 250 expendable temperature and salinity probes along the continental shelf to measure the volume, extent, of warm, salty Atlantic Water. These data, along with fundamental new and critical observations of airborne marine gravity and ship-based observations of the sea floor geometry will provide a revolutionary data set for modeling ocean/ice interactions and lead to improved estimates of global sea level rise.
