Radiocarbon dates for an elevational gradient by Toolik Lake, North Slope of Alaska 1988.

Abstract: 

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.

EXPERIMENTAL METHODS: 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. The sections were further divided by depth at intervals of 4 - 6 cm for determination of the desired parameters. Percent moisture was determined by drying to constant weight at 105 degrees C and Loss On Ignition, to be converted into percent organic carbon, determined by combustion at 550 degrees Celcius until constant weight.

Notes: I believe this core was taken near the shore of the far western bay of Toolik Lake. Jim Laundre 2011
