Recent ice conditions in North-Norwegian Porsangerfjorden
Ice is a common occurrence in mainland Norwegian fjords in the vicinity of river mouths in winter. Fjord ice provides a wide array of services to society, including (1) acting as a coastal buffer (e.g. from pollution) and marine hazard; (2) providing a platform for recreational activities (e.g., tra...
