Mountain glaciers of southernmost Greenland, 2018
Our 2018 expedition to southernmost Greenland focused on glacier-fed lakes containing sedimentary records of Holocene mountain glacier fluctuations. With help from geophysical (sub-bottom profiling) equipment, we obtained exciting suites of sediment cores from three lakes with diverse mountain glaciers within their catchments. Thank you to NSF’s Division of Polar Programs for support of this research.

South Greenland’s Holocene climate history, 2016
A press release from the Institute of Sustainability and Energy at Northwestern describes some of this NSF-CAREER project’s objectives. The first of three project field seasons took place in summer 2016, recovering Holocene sediment records at remote, medium- to high-elevation non-glacial lakes south of Narsarsuaq. A few field photos by Ph.D. student Everett Lasher are below. Thank you to NSF’s Division of Polar Programs for support of this research.
Glacier loss and climate change in southwest Greenland, 2015
This project, funded by the National Geographic Society, investigates the history of (currently disappearing) alpine glaciers south of Nuuk, Greenland’s capitol. In summer 2015 we cored several glacier-fed and nonglacial lakes in the Tasiusarsuaq region. These sedimentary records are allowing us to reconstruct Holocene glacier fluctuations and to constrain corresponding changes in local climate.
