Photoglossary
Permafrost
Phenomena related to permafrost are widespread on Svalbard. A few examples are shown on this page.
Stone circles in Brøggeralen, southwest of Ny Ålesund (JA).
Detail of the same stone circles as in the previous photo, fisheye lens (JA).
Small rock glaciers at the base of a cliff (Steinflåstupet) W of Ny Ålesund (JA).
Small rock glacier in Brøggeralen, SW of Ny Ålesund (panorama, requires scrolling to the right; JA).
Ice wedge polygons along the SW coast of Brøgger Halvøya (JA).
Rapid spring runoff causes considerable fluvial erosion and delta formation (SW coast of Brøgger Halvøya, JA).
Alluvial fan, ice wedge polygons and raised beaches (SW coast of Brøgger Halvøya, JA).
Solifluction is evident in Longyerbyen where posts formerly used as foundations of tramway pylons have tilted downslope (JA).
Buildings constructed in areas affected by permafrost need to be insulated from the ground (UNIS, The University Centre in Svalbard; JA).
All photos were taken in summer 2009 (J. Alean)
