Home To measure water depth and salinity, the OMG project dropped probes by plane into fjords along reenland’s coast. Shown here is one such fjord in which a glacier is undercut by warming water. The Brown water is caused by sediment being dredged up from the base of the glacier by meltwater plumes.

The OMG mission also carried out depth and salinity measurements of Greenland’s fjords occupied by marine-terminating glaciers by boat. These measurements complement those provided by probes dropped from aircraft to create the most comprehensive survey to date of Greenland’s melting glaciers. (NASA/JPL-Caltech)
