Thermokarst lake morphometry and erosion features in two peat plateau areas of Northeast European Russia

High-resolution satellite remote sensing analysis (n=637 lakes) and field measurements (n=29 lakes) of two peat plateau areas in northeast European Russia were carried out to investigate lake morphology, map shoreline erosion indicators and assess possible orientation patterns in lake and shore morp...
