Paleoglaciology of Alaska
Listed in NASA Earthdata CMR
The Paleoglaciology of Alaska project involves scientists to estimate past climate parameters from glacial-geologic records.
Description
This project combines field research and cosmogenic-surface-exposure dating with GIS analysis of Alaskan glaciers that existed during the Last Glacial Maximum (LGM). -Former glacier extents, coupled with high-resolution Digital Elevation Models (DEM's), permit us to quantify past Equilibrium Line Altitudes (paleo-ELA's). -For each glacier, this parameter records a balance between winter precipitation and summer temperature. -Dense spatial arrays of hundreds of paleoELA's within 8 broad mountainous regions clarify: microclimatic vs. regional climatic controls on glacier growth; synoptic views of atmospheric moisture circulation; and spatially varying LGM aridity for comparison with numerical climate simulations.
