Model code supporting "Evidence for a more extensive Greenland Ice Sheet in southwestern Greenland during the Last Glacial Maximum"
(2021-02)The maximum extent and elevation of the Greenland Ice Sheet (GrIS) in southwestern Greenland during the Last Glacial Maximum (LGM, 26-19.5 ka) is poorly constrained. Yet the size of the GrIS during the LGM helps inform ... -
Data supporting "Controls on Greenland moulin geometry and evolution from the Moulin Shape model"
(2021-02-03)Nearly all meltwater from glaciers and ice sheets is routed englacially through moulins, which collectively comprise approximately 10–14% of the efficient englacial–subglacial hydrologic system. Therefore, the geometry and ... -
How stable is the Greenland Ice Sheet?

Data supporting "Challenges in predicting Greenland supraglacial lake drainages at the regional scale"
(2020-08-30)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 ... -
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 ... -
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 ... -
User’s Manual for: A Visual Survey of Global Slab Geometries with ShowEarthModel and Implications for a Three-dimensional Subduction Paradigm
(2018-05-11)This is a user manual for the ShowEarthModel referenced in the article "A Visual Survey of Global Slab Geometries With ShowEarthModel and Implications for a Three‐Dimensional Subduction Paradigm." It explains workflows and ... -
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 ... -

Movies for: A Visual Survey of Global Slab Geometries with ShowEarthModel and Implications for a Three-dimensional Subduction Paradigm
(2018-01-05)Increasing volumes of digital data, combined with advances in visualization, now allow for a new three-dimensional (3D) conceptualization of modern subduction systems. Here we present sixteen movies of visual exploration ... -
