Donald Schell, 1989 Radiocarbon dates for an elevational gradient by Toolik Lake, North Slope of Alaska 1988.. 10.6073/pasta/90a45bbe7265d037228609a2054afac5
Two cores of peat, approximately 15 cm2, were cut to the depth at which mineral soils were encountered at each site. The sites of sampling correspond to an elevational gradient leading from the lakeside upslope to the begining of the water track at the ridgetop. Each sample was divided into three sections, one section to be used for radiocarbon age , one for loss on ignition, and the remainder to be kept for future needs.
Donald Schell, 1991 Peat cores were collected along the Dalton Highway for the analysis of soil properties, 13C and percent of modern age, North Slope, Alaska 1989.. 10.6073/pasta/3ea4ba41db1236a5fea4a3f1cad8bea9
Peat cores were collected along the Dalton Highway in 1989 and analysed for percent moisture, percent organic carbon, bulk densitey, del C-13, and radiocarbon content at varying depth intevals throughout the core. Samples were collected to the mineral zone and kept in cold storage until analysis. Samples were collected from 12 sites.
