Research goals

The general objective is to increase the understanding of the physical and chemical properties and processes of surface snow and their sensitivity to climate variability and feedback mechanisms in Antarctica. The research area is in the western Dronning Maud Land, Antarctica. Currently the aim is to examine in more detail the spatial distribution of the snow properties using field measurements as well as remote sensing methods, mapping the extent of summer melting and model related meltwater percolation and re-freezing processes.

Methods

In-situ observations of physical and chemical properties of snow have been collected in FINNARP expeditions. Satellite remote sensing and modeling are presently utilized for investigations.
