The aim is to investigate the link between ocean temperatures and melting glaciers

The US space agency NASA is currently in the process of mapping the seabed in western Greenland as part of the Oceans Melting Greenland mission (OMG).
OMG is a five-year-long project that will pave the way for improved estimates of the rise in sea level and explore the link between ocean temperatures and melting glaciers in Greenland.
Researchers will survey Greenland’s coastal glaciers using a device aboard NASA’s Gulfstream III aircraft. The Glacier and Ice Surface Topography Interferometer can generate high resolution and high precision elevation measurements.
Along with other surveys in the region, this mission will provide improved estimates of the rise in global sea levels.
