Description :
These data are measured in High Arctic over an observatory basin, located at 79°N on the W coast of Svalbard.
Austre Lovén is a small 4.5 km² polythermal glacier in constant decline since the end of the LIA. The surrounding catchment is no more than 10 km² and exhibits a significant periglacial area with geomorphological features allowing an all-year monitoring.
On the glacier, a network of 40 stakes is deployed and measured at the end of the hydrological year i.e. early October. This routine maintenance is carried out twice a year and stakes are regularly changed depending on the glacier topographical evolution.
The entire observatory is referenced through the WGMS (World Glacier Monitoring Service) and is part of the french IR OZCAR.

General metadata

Data acquisition date : from Oct 2008 ongoing
Data acquisition methods :
  • Observational data :
    The mass balance of a glacier is the difference between accumulation and ablation losses (melting of snow and ice), expressed in water equivalent volume, over a hydrological year.
    Measurements are taken in situ using beacons inserted in the ice. For each one, we measure how much they protrude from the ice, enabling us to deduce gains or losses by comparison from one year to the next.
    At the same time, where melting is more active (glacier front), a geodetic measurement is made using DTM difference (DoD) from LiDAR point cloud acquisitions.

Additional information :
The data comes from an observatory programme supported by the Institut Polaire Paul Emile Victor (IPEV). There is two missions a year to spot measurements and recurrent measurements (MB, temperatures and automatic photo stations) in order to make long-term observations.
