Radiocarbon Dates and Pollen Data, Peterson Erosional Remnant, Arctic Coastal Plain, Alaska

Listed in National Center for Atmospheric Research

This data set consists of pollen data and radiocarbon (14C) dates resulting from microscopic analysis and mass spectrometry of soil cores taken from the Peterson Erosional Remnant, located on the Arctic Coastal Plain near Barrow, Alaska.

Description

Data are contained in four files, and include raw pollen counts listed by depth; counts for each coded pollen or microfossil type for each depth; the percent of each pollen or microfossil type by depth; radiocarbon (14C) dates expressed in calibrated years BP; and a pollen dictionary of codes used and Latin pollen/microfossil names.

Data are in ASCII format. These data are part of a study of paleoenvironment, processes, and carbon stocks of thaw-lake basins on the Arctic Coastal Plain. The Peterson Erosional Remnant is a "non-basin" site that can be used to determine the overall age of the landscape in which thaw lakes have formed and drained.
