View Arctic Elevation Data with ArcDem Explorer

ArcticDEM is a project that is working to produce digital elevation models of the Arctic in order to see how topographical changes are occurring over time, such as the rate at which glaciers are receding.

Seabed surveys in the Canadian Arctic are done using using multi-beam sonar, sweep multi-transducer sweep systems and airborne laser bathymetry systems. Image: Canadian Hydrographic Service (CHS).
