Despite racing against impending harsh weather conditions, a red and white World War II aircraft flew slowly and steadily over the icy waters surrounding Greenland in August and September. Three weeks delayed by pandemic restrictions, scientists from NASA’s Jet Propulsion Laboratory inside this retrofitted DC-3 plane started dropping hundreds of probes as part of an annual expedition known as the Oceans Melting Greenland(OMG) Project.

NASA research shows that Jakobshavn Glacier, which has been Greenland's fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face. Jakobshavn is now flowing more slowly, thickening, and advancing toward the ocean instead of retreating farther inland. The glacier is still adding to global sea level rise — it continues to lose more ice to the ocean than it gains from snow accumulation — but at a slower rate.
Only seven months after NASA's Oceans Melting Greenland (OMG) mission wrapped its last field campaign on the world's largest island, an OMG crew is back in Greenland to collect more data. With two or three field projects a year since 2016, no wonder OMG has made the most comprehensive measurements yet of how ocean water lapping at the undersides of Greenland's melting glaciers affects them. All that data has answered a lot of existing questions — and it's raised plenty of new ones.

Researchers in NASA's Oceans Melting Greenland campaign release scientific probes from an airplane into the seawater along the coast of Greenland. The probes are part of a five-year effort to improve our understanding of the ocean's role in Greenland's rapid ice loss.
With a new research plane and a new base to improve its chances of outsmarting Atlantic hurricanes, NASA's Oceans Melting Greenland campaign takes to the sky this week for its third year of gathering data on how the ocean around Greenland is melting its glaciers.
New maps of Greenland’s coastal seafloor and bedrock beneath its massive ice sheet show that two to four times as many coastal glaciers are at risk of accelerated melting as previously thought.
Oceans Melting Greenland (OMG) is a NASA Mission led by JPL Scientist Josh Willis to understand the role that the ocean plays in melting Greenland’s glaciers. From the sky and the sea, OMG gathers data about water temperatures and the glaciers all the way around Greenland to get a better idea of just how fast the ice is melting, and how fast global sea levels will rise.
On Friday June 3, 2016, the Oceans Melting Greenland mission had its first successful test of the system for dropping ocean probes from the Gulfstream-III aircraft into the ocean. The team dropped a single probe into the Gulf of Mexico about 100 miles offshore of Houston as a T-38 chase aircraft monitored.

The new NASA airborne mission Oceans Melting Greenland (OMG) will pave the way for improved estimates of sea level rise by addressing the question: To what extent is the ocean melting Greenland’s ice from below? The mission will observe changing water temperatures and glaciers that reach the ocean around Greenland from 2015 to 2020.
