Summary

This thesis presents a 15 ka record of Holocene paleolimnological change from Greyling Lake (61.4 degree N, 145.7 degree W, 1015 m asl), a proglacial lake in the Chugach Mountains of south-central Alaska. Fluctuations in paleolimnological conditions were reconstructed through the analysis of fossil diatom assemblages preserved within a sediment core taken from the central lake basin. The composition of diatom communities, together with physical and chemical proxies (magnetic susceptibility, bulk density, grain size, and organic matter), were used in the reconstruction. As a proglacial lake, Greyling Lake provides a record of paleoclimate change in southern Alaska through the erosive characteristics of nearby glaciers. Changes in the [...]
