Abstract: 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
