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
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 ...
Maximum Southwest Greenland Ice Sheet recession in the early Holocene
(American Geophysical Union, 2020-01-03)
Establishing the timing of maximum Holocene warmth in the Arctic is critical for understanding global climate system response to external forcing. In Greenland, challenges in obtaining climate records that span the full ...
Data supporting "Challenges in predicting Greenland supraglacial lake drainages at the regional scale"
A leading hypothesis for the mechanism of fast supraglacial lake drainages is that transient extensional stresses briefly allow crevassing in otherwise-compressive ice flow regimes. Lake water can then hydrofracture the ...
