Collaborative Research: Resolving centennial-to-millennial-scale trends in glacier extent and lake sedimentation in the Brooks Range, Arctic Alaska

Lead PI: Dr. William J. D'Andrea

Unit Affiliation: Biology and Paleo Environment, Lamont-Doherty Earth Observatory (LDEO)

September 2011 - August 2015
North America ; Alaska
Project Type: Research

DESCRIPTION: The goal of this collaborative project to reconstruct late Quaternary climate and glacier change in Arctic Alaska. The investigators propose to develop records of climate change from lake sediments and records of glacier fluctuations using proglacial lake sediments and beryllium-10 dating of glacial features to address questions centered around four intervals of pronounced global change: (1) Last Glacial Maximum; (2) Deglaciation; (3) Holocene Glaciation; and (4) Little Ice Age.

OUTCOMES: The project has several educational components, including support four graduate students and several undergraduate students and visits to the community of Anaktuvuk Pass to deliver presentations on climate research and the Brooks Range.
