1 Introduction The Arctic coastline is more than 400,000 km long. This is about a third of the world's coastline [1]. Much of this coastline is frozen as permafrost (sediment, soil and rock that is frozen for more than two consecutive years). These coasts are often rich in ice (i.e., ground ice) and therefore highly vulnerable to thaw and erosional processes [2, 3].
