LEAD: NASA researchers are making the first detailed measurements of changes along Greenland's 27,000 mile-long coastal fiords and the outlet glaciers to see how Greenland ice is melting from the bottom up.
1. Relative warm ocean currents flowing into the fiords are melting the bottoms of some of the glaciers.
2. Accurate maps of the sea floor, ocean temperatures and salinity data will help scientists make better estimates of just how much melting is taking place along the coast.
TAG: This specific mission will last 5 years and will lead to improved climate models about sea level rise around the world.
