Tarfala Data

Mårmaglaciären

Mårmaglaciären is located approximately 25 kilometres to the northwest from Tarfala and Storglaciären in the Mårma massif. It is a valley glacier heading eastward with an average depth of 140 metres and a maximum depth of 270 metres. The glacier tongue is dammed inside huge ice cored moraines. The glacier has been subject to much research focusoing on its polythermal structure (Holmlund et al., 1996) and the possibility to extract paleoclimatic records from polythermal glaciers.

Mårmaglaciären was first documented by Enquist who photographed its tongue in 1918. The second documentation dates to 1952 when the glacier front was well documented by photographs taken by Valter Schytt. The moraines were examined by Østrem in order to estimate the thickness of the ice core in the ridges (Østrem, 1965). In 1968 the glacier was included in the glacier front monitoring programme.

Maps in the scale 1:10 000 has been constructed, based on aerial photographs taken in 1959, 1978 and 1991. Only the 1978-map was printed.

Monitoring data

The mass balance of the Mårmaglaciären has been measured since 1990.
