Rapid Response Research: Accessing New Sea Ice in an Arctic Winter Polynya
Recent years have seen the loss of massive amounts of multi-year sea ice from the Arctic Ocean and its replacement by first year sea ice. As first year ice freezes, a crystalline structure known as frost flowers forms on its surface. Frost flowers are delicate structures, high in brine content, and...
