Satellite image showing the relative warmth of seawater behind Antarctic icebergs on 9 March 2022. The warmest areas (yellow, orange and red) depict open water and thin, newly formed sea ice. The coldest areas (blue and white) are older, thicker ice, including the icebergs and broken ice rubble in their paths. Image obtained by combining data from the Operational Land Imager (OLI) and the Thermal Infrared Sensor instruments (TIRS) on the Landsat 8 satellite.
