MODIS: Swirls along an Ice Highway
Sea water off the east coast of Greenland looked a bit like marbled paper in October 2012.
The shifting swirls of white were sea ice, as observed by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite on October 17, 2012. In fact, this ice moved discernibly between October 16 and October 17. Thin, free-drifting ice moves very easily with winds and currents.
