We provide a mechanistic explanation for observed metrics for drumlins, which represent their sizes and shapes. Our explanation is based on a concept of drumlin growth occurring through a process of instability, whereby small amplitude wave forms fir... Read More about On the size and shape of drumlins.

Journal of Geophysical Research: Earth Surface, 118(3), 1210-1226. https://doi.org/10.1002/jgrf.20088

[1] Discharge from marine-terminating outlet glaciers represents a key component of the Greenland Ice Sheet mass budget and observations suggest that mass loss from northwest Greenland has recently accelerated. Despite this, the factors controlling o...

Observations of ocean-terminating outlet glaciers in Greenland and West Antarctica1, 2, 3, 4, 5, 6 indicate that their contribution to sea level is accelerating as a result of increased velocity, thinning and retreat7, 8, 9, 10, 11. Thinning has also... Read More about Rapid, climate-driven changes in outlet glaciers on the Pacific coast of East Antarctica.

Evidence for Hesperian glaciation along the Martian dichotomy boundary (2013)
Journal Article

Meltwater drainage systems beneath ice sheets are a poorly understood, yet fundamentally important environment for understanding glacier dynamics, which are strongly influenced by the nature and quantity of meltwater entering the subglacial system. C... Read More about A map of large Canadian eskers from Landsat satellite imagery.
