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 Nordvesto, Carey Islands, Greenland, in 2001--as part of efforts to collect continuous samples of Arctic peat cores for an environmental archive of heavy metal and persistent organic pollutants. A new system for precise slicing of frozen peat cores and accurate volumetric sub-sampling of slices is also described and illustrated, since pre-analytical preparation of the cores is important for accurate trace analyses, as well as for determination of net ...
