“…In 1965, Geoffray (1968 implemented a network of 17 stakes on AL. Preliminary hydro-glaciological investigations conducted by Vivian (1964) were pursued by Vincent and Geoffray (1970). Two decades later, Griselin (1982Griselin ( , 1985 proposed the first hydrological balance of the AL catchment.…”

The change of Austre Lovénbreen, a 4.5 km 2 land-based glacier along the west coast of Spitsbergen, is investigated using geodetic methods and mass balance measurements over 1948 . For 2008, annual mass balances computed on 36-stake measurements were obtained, in addition to annual mass balances reconstructed from the neighbouring glaciers, Midtre Lovénbreen (1968Lovénbreen ( −2007 and Austre Brøggerbreen (1963Brøggerbreen ( −1967. The mean rate of glacier retreat for 1948-2013 is −16.7 ± 0.3 m a −1 . Fluctuations in area (1948-2013 mean, −0.027 ± 0.002 km 2 a −1 ) showed a slowing as the glacier recedes within its valley from 1990 to 1995. For 1962-2013, the average volume loss calculated by digital elevation model subtraction of −0.441 ± 0.062 m w.e. a −1 (or−0.54 ± 0.07% a −1 ) is similar to the average annual mass balance (−0.451 ± 0.007 m w.e. a −1 ), demonstrating a good agreement between the loss rates computed by both methods over 1962−2013. When divided in two periods (1962−1995 and 1995−2013), an increase in the rate of ice mass loss is statistically significant for the glacier volume change. The 0°C isotherm elevation (based on mean May-September air temperatures) is estimated to have risen by about 250 m up to the upper parts of the glacier between 1948 and 2013. The glacier area exposed to melting during May to September almost increased by 1.8-fold while the area reduced by a third since 1948. Within a few years, the glacier area exposed to melting will decrease, leading the upper glacier parts under the 0°C isotherm while the snout will keep on retreating.

“…Hydrological investigations in the river catchments of Svalbard began rather late compared to investigations at the turn of the 19th to 20th century of some glacial catchments in northern Scandinavia in connection with their hydropower station utilisation (Vivian 1964;Klǽ boe 1948). In the Spitsbergen region hydrological investigations, including glaciological and meteorological observations, began only in the last decade of the 20th century (Vatne et al 1995;Hodgkins 1997;Killingtveit et al 2003).…”

The article examines characteristics of meteorological and runoff time-series collected from the Scott Glacier catchment, Svalbard, during 2005 and2006. The river discharge of Scottelva (Scott River) was monitored at a gauging station situated near the mouth of Recherche Fjord. Meteorological time-series (i.e. air temperature and precipitation) were monitored in Calypsobyen. The analysis shows interrelationships between meteorological and hydrological time-series, and that the runoff of Scottelva depends on the amount and intensity of glacial ablation. Total ablation for the Scott Glacier was estimated at 63.9 cm water equivalent in the 2005 season and 98.2 cm water equivalent in the 2006 season. A total of 64% and 72% of the discharge from the Scottelva in the respective 2005 and 2006 seasons came from surface ablation of the glacier.
