Assessing permafrost erosion in the Canadian Beaufort Sea, Herschel Island - a biomarker approach ...
Herschel Island is the remnant of an ice-push moraine, formed during the farthest advance of the Laurentide Ice Sheet in the late Wisconsin. The island is located in the Canadian Beaufort Sea, in the northwestern part of the Yukon Territory. A marine depression (Herschel Basin), southeastern adjacen...
