Miriam C. Jones, Guido Grosse, Benjamin M. Jones, Katey Walter Anthony
2012, Journal of Geophysical Research G: Biogeosciences (117) G00M07
Thermokarst lakes and peat-accumulating drained lake basins cover a substantial portion of Arctic lowland landscapes, yet the role of thermokarst lake drainage and ensuing peat formation in landscape-scale carbon (C) budgets remains understudied. Here we use measurements of terrestrial peat thickness, bulk density, organic matter content, and basal radiocarbon age...
