AWI researchers develop new method to detect platelet ice over large distances. Sea ice physicists of the Alfred Wegener Institute (AWI) have developed a new method that allows them for the first time to efficiently determine the distribution and thickness of what researchers call a sub-ice platelet layer. This several metre thick layer of delicate ice crystals is predominantly found beneath coastal Antarctic sea ice, and at present knowledge about its spatial distribution is very limited. This phenomenon, which is also known as platelet ice, is of central importance in the coastal regions of the Antarctic, influencing sea ice properties and the associated ecosystem in various ways, and serving as an indicator for the state of melting ice shelves. The researchers published their results with open access in the current issue of the journal Geophysical Research Letters.
