Characteristics and radiocarbon ages of four retrogressive thaw slumps on Herschel Island and King Point ...
Four retrogressive thaw slumps (RTS) located on Herschel Island and the Yukon coast (King Point) in the western Canadian Arctic were investigated to compare the environmental, sedimentological and geochemical setting and characteristics of zones in active and stabilised slumps and at undisturbed sit...

Four retrogressive thaw slumps (RTS) located on Herschel Island and the Yukon coast (King Point) in the western Canadian Arctic were investigated to compare the environmental, sedimentological and geochemical setting and characteristics of zones in active and stabilised slumps and at undisturbed sites.

Organic carbon contents were lower in slumps than in the surrounding tundra, and the density and compaction of slump sediments were much greater.
