Abstract:

Measurements of active-layer thickness were carried out at CALM Site P1 (Calypsostranda), on the southern border of Recherche Fiord (Bellsund region) on the island of Spitsbergen, Svalbard Archipelago. The aim of the studies was to determine the depth and rate of summer thawing and to explain the reasons for local differences. This is of significance owing to the role of the active layer in processes governing development of the periglacial morphogenetic zone. Local factors—including moisture content, vegetation cover, and slope aspect—are important determinants of active-layer thickness and its variability in the Calypsostranda area. Formal sampling and measurement programs, such as those administered by CALM affiliates, are important for discerning between local effects and long-term impacts of climatic changes.
