Finding open water in Greenland’s icy seas

“Three, two, one … drop!”

Researchers in NASA’s Oceans Melting Greenland campaign heard that phrase 239 times this fall. Each time, it triggered a team member to release a scientific probe 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.

Since 2016, OMG has been collecting measurements around the huge island on three separate trips a year. Each spring, a research aircraft measures the height of the ice sheet after the winter snows. In the summer, boat-borne instruments map the seafloor around Greenland. In September or October, OMG principal investigator Josh Willis of NASA’s Jet Propulsion Laboratory in Pasadena, California, and a team of researchers, pilots and engineers fly to Greenland and drop up to 250 biodegradable probes in the ocean, circling the entire coast to measure the temperature of the water touching Greenland’s glaciers.
