Ground temperature changes on the Kaffiøyra Plain (Spitsbergen) in the summer seasons, 1975–2014
Abstract This paper provides an overview of the results of research on changes in ground temperature down to 50 cm depth, on the Kaffiøyra Plain, Spitsbergen in the summer seasons. To achieve this, measurement data were analysed from three different ecotopes (CALM Site P2A, P2B and P2C) – a beach, a...
