Increased sea-level contribution from northwestern Greenland for models that reproduce observations Open
State-of-the-art ice sheet model simulations used in the Ice Sheet Model Intercomparison Project (ISMIP) that informs the Intergovernmental Panel on Climate Change tend to underestimate observed mass loss from the Greenland Ice Sheet, lead…

Bridging Observations and Models: Isolating Frictional and Frontal Controls on Glacier Dynamics in Northwestern and Central-West Greenland Open
The Greenland Ice Sheet is a major contributor to present-day sea-level rise, with ice dynamics playing a central role in its mass loss. Previous studies suggest that Greenland’s glaciers can be broadly classified into three distinct…

Improving modeled ice dynamics in Northwest Greenland with transient calibration: From multi-decadal trends to seasonal cycles Open
State-of-the-art ice sheet model simulations used in the Ice Sheet Model Intercomparison Project (ISMIP) show a mismatch with recent observations of dynamic ice sheet change. In particular, the difference between the modeled and observed c…

Uncertainty in Reconstructing Paleo‐Elevation of the Antarctic Ice Sheet From Temperature‐Sensitive Ice Core Records Open
Paleotemperature reconstructions from ice cores are mixed signals of changes in climate and ice‐surface elevation. A common, temperature‐based paleoaltimetry method suggests these signals can be disentangled by comparing two proxy location…

icepack: a new glacier flow modeling package in Python, version 1.0 Open
We introduce a new software package called “icepack” for modeling the flow of glaciers and ice sheets. The icepack package is built on the finite element modeling library Firedrake, which uses the Unified Form Language (UFL), a domain-spec…

In situ cosmogenic <sup>10</sup> Be– <sup>14</sup> C– <sup>26</sup> Al measurements from recently deglaciated bedrock as a new tool to decipher changes in Greenland Ice Sheet size Open
Sometime during the middle to late Holocene (8.2 ka to ∼ 1850–1900 CE), the Greenland Ice Sheet (GrIS) was smaller than its current configuration. Determining the exact dimensions of the Holocene ice-sheet minimum and the duration that the…

An englacial hydrologic system of brine within a cold glacier: Blood Falls, McMurdo Dry Valleys, Antarctica Open
Taylor Glacier hosts an active englacial hydrologic system that feeds Blood Falls, a supraglacial outflow of iron-rich subglacial brine at the terminus, despite mean annual air temperatures of −17°C and limited surface melt. Taylor Glacier…
