Nigardsbreen (61°42'N, 7°08'E) is one of the largest and best known outlet glaciers from the Jostedalsbreen ice cap. It has an area of 46 km2 (2013) and flows southeast from the centre of the ice cap. It accounts for about 10 % of the total area of Jostedalsbreen. Nigardsbreen range from 1952 to 330 m a.s.l., with 88 % of its area located above 1400 m a.s.l. The large upper part of the glacier is a plateau, with an even gently sloping surface down to about 1400 m a.s.l. Between 1300 and 800 m a.s.l. the glacier flows through a heavily crevassed icefall. The distance along a central flow line is about 9 km, from the upper ice divide north-west of Kjenndalskruna, to the glacier terminus. The terminus has been land-based since 1973, but calved previously into the lake Nigardsbrevatnet. See photos of the glacier.
Glaciological investigations include mass balance observations since 1962 and glacier length change measurements since 1899. The results can be viewed and downloaded from NVEs glacier data portal.
Results from NVE’s mass balance measurements on Nigardsbreen are published in the series 'Glaciological investigations in Norway'.
Glacier length change
Since the length change measurements started in 1899 the frontal retreat of Nigardsbreen has been mora than 2.5 km. The greatest recession occurred in the period 1940-1970. From 1988 to 2003, however, the glacier length increased with 280 metres. After 2003, the frontal retreat has continued.
