An Improved Motorized Corer and Sample Processing System for Frozen Peat
ABSTRACT. An improved corer and associated equipment for obtaining continuous samples of frozen peat are described. We developed the system through laboratory and field trials—on Bathurst Island, Nunavut, Canada in 2000 and Nordvestø, Carey Islands, Greenland, in 2001—as part of efforts to collect c...
