Accumulation of Excess Ground Ice in an Age Sequence of Drained Thermokarst Lake Basins, Arctic Alaska
The excess ice content of near‐surface permafrost near Barrow, Alaska, was estimated using cores collected from 57 drained thermokarst‐lake basins and additional cores from a nearby landform unaffected by thaw‐lake processes. The excess ice content, estimated using soil cryostructures, increased wit...

| Summary: | The excess ice content of near‐surface permafrost near Barrow, Alaska, was estimated using cores collected from 57 drained thermokarst‐lake basins and additional cores from a nearby landform unaffected by thaw‐lake processes. The excess ice content, estimated using soil cryostructures, increased with surface age: from 20 per cent in young basins |
