Resolving combined influences of inflow and evaporation on western Greenland lake water isotopes to inform paleoclimate inferences
(Springer Netherlands, 2020-02-05)
Stable isotopes of oxygen (δ18O) and hydrogen (δ2H) in precipitation are widely employed tracers of the global hydrologic cycle, and are frequently inferred from lake-water-derived proxies in sediments of high-latitude ...
Ice sheet influence on atmospheric circulation explains the patterns of Pleistocene alpine glacier records in North America
(Elsevier, 2020-01-27)
We explore the hypothesis that the relative size of Pleistocene ice sheets in North America modulated regional climate and alpine glaciation. We compare Pleistocene alpine glacier chronologies across North America with a ...
Long-term support of an active subglacial hydrologic system in Southeast Greenland by firn aquifers
(American Geophysical Union, 2019-04-29)
The state of the subglacial hydrologic system, which can modify ice motion, is sensitive to the volume and rate of meltwater reaching it. Bare-ice regions rapidly transport meltwater to the bed via moulins, while in certain ...
