AbstractWithin a study of nivation processes and landforms, the freeze-thaw activity is being measured at two sites in northern and southern Sweden. The aim is to test the hypothesis of active nivation occurring in the periglacial environment of northern Sweden, as opposed to the temperate south, in the present climate. Attempts will be made to relate the freeze-thaw activity to the operation of mass wasting processes at snowpatch sites. The report describes the study sites and the instrumentation used and concludes with some brief comments on initiated measurements.
