Frozen water in all its forms — glaciers, ice sheets, sea ice, permafrost, seasonal snow cover. While Denmark proper has limited cryosphere data, Greenland makes this twig critical for the Danish realm.
Scope
- Glaciers: Ice mass, flow velocity, calving fronts, volume change (Greenland ice sheet)
- Sea ice: Extent, thickness, concentration, ice type classification
- Permafrost: Distribution, active layer depth, ground temperature (Greenland, Arctic)
- Seasonal snow: Snow cover extent, snow depth, snow water equivalent (SWE)
Greenland Context
The Greenland Ice Sheet is one of the most studied cryospheric features on Earth. Danish institutions (GEUS, DMI) produce critical datasets on ice mass balance, firn temperature, and meltwater runoff that feed into global sea level projections.
Classical Theme Mappings
No direct classical theme — cryosphere data is typically classified under Inland Waters (ISO) or Hydrography (INSPIRE) for ice sheets, and Meteorological Features for snow cover.
