TL;DR: In this article, the relative age of 77 basins on the Barrow Peninsula was estimated using the degree of plant community succession and verified by radiocarbon-dating material collected from the base of the organic layer in 21 basins.

TL;DR: In this article, the authors identify erosional remnants of a former topographic surface that predates the formation of the thaw lakes, which are characterized by a higher elevation, a thick organic layer with very high ground ice content in the upper permafrost and a plant community somewhat atypical of the region.

TL;DR: In this article, modern and fossil pollen analyses have established the local vegetation succession and landscape evolution along the Meade River near Atqasuk, Alaska, and three data sets were analyzed: (1) a 142 cm-long peat deposit on the exposed river bluff face, (2) a short, 13 cm peat monolith from the near-surface sediment, and (3) a modern data set of surface samples collected along a transect representative of a geomorphic gradient of low-center, transitional, and high-center polygons.

TL;DR: In this article, surface pollen samples from drained thaw-lake basins near Barrow, Alaska were collected and analyzed, and the results indicated that the different phases of the thaw lake cycle are accompanied by changes in plant composition.

TL;DR: A group of ice-cored frost mounds formed during the winter of 1995-1996 near Barrow, Alaska in a drained thaw lake basin this paper, and were observed in mid-August 1996.
