Geomorphology and style of plateau icefield deglaciation in fjord terrains: the example of Troms‐Finnmark, north Norway
Abstract In spite of a widespread distribution, the way in which plateau icefields affect the glaciation and deglaciation of adjacent terrains is not particularly well‐known. This paper aims to identify how the deglaciation of the fjord and plateau terrain of north Norway has influenced the glacial...
