mapsontheweb:Left: Greenland topography color-coded from 4,900 feet (1,500 meters) below sea level (dark blue) to 4,900 feet above sea level (brown). Right: regions below sea level connected to the ocean, either shallower than 600 feet (200 meters, light pink); between 600 and 1,000 feet (300 meters, dark pink); or continuously deeper than 1,000 feet below sea level (dark red). The thin white line shows the current extent of the ice sheet.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. -- source link
