Coastal landscape degradation and disappearance of Davislaguna Lake, Sørkappland, Svalbard, 1900–2021
Abstract The paper describes the transformation of the coastal landscape near former Davislaguna Lake, SE Spitsbergen. It is a comparative study which outlines the changing state of the area based on old maps, other archival materials, remote sensing data from the years 1900 to 2021, and our own fie...
