While waiting, the extra time is used to resupply with spares and food. Once at Tarfala, field work will be carried out at Storglaciären and Rabots glaciär (two of the World Glacier Monitoring Service’s so-called reference glaciers), Mårmaglaciären, and Riukojietna.
The time lapse camera, overlooking Lake Tarfala, will also be visited, and high-resolution pictures taken since the fall will be collected. Low-resolution footage is sent occasionally (depending on weather) via MMS. The images collected contribute to a better understanding of lake ice phenology, which impacts lake mixing and other important processes in the lake.
