Journal Article
Margold, M., Stokes, C., Clark, C., & Kleman, J. (2015). Ice streams in the Laurentide Ice Sheet: a new mapping inventory. Journal of Maps, 11(3), 380-395. https://doi.org/10.1080/17445647.2014.912036

Rapidly flowing ice streams dominate the drainage of continental ice sheets and are a key component of their mass balance. Due to their potential impact on sea level, their activity in the Antarctic and Greenland Ice Sheets has undergone detailed scr...

Asynchronous response of marine-terminating outlet glaciers during deglaciation of the Fennoscandian Ice Sheet (2014)
Journal Article
Stokes, C., Corner, G., Winsborrow, M., Husum, K., & Andreassen, K. (2014). Asynchronous response of marine-terminating outlet glaciers during deglaciation of the Fennoscandian Ice Sheet. Geology, 42(5), 455-458. https://doi.org/10.1130/g35299.1

Recent studies have highlighted the dynamic behavior of marine-terminating outlet glaciers over decadal time scales, linked to both atmospheric and oceanic warming. This helps explain episodes of nearly synchronous flow acceleration, thinning, and re...

Gale crater is a ~154-km-diameter impact crater formed during the Late Noachian/Early Hesperian at the dichotomy boundary on Mars. Here we describe potential evidence for ancient glacial, periglacial and fluvial (including glacio-fluvial) activity wi... Read More about A cold hydrological system in Gale Crater, Mars.

This paper presents a glacial geomorphological map of the landforms created by five large ice lobes that extended eastwards from the southernmost reaches of the Patagonian Ice Sheet during the Quaternary period. The study is focussed on Tierra del Fu...

Understanding controls on rapid ice-stream retreat during the last deglaciation of Marguerite Bay, Antarctica, using a numerical model (2014)
Journal Article
Jamieson, S., Vieli, A., Ó Cofaigh, C., Stokes, C., Livingstone, S., & Hillenbrand, C. (2014). Understanding controls on rapid ice-stream retreat during the last deglaciation of Marguerite Bay, Antarctica, using a numerical model. Journal of Geophysical Research: Earth Surface, 119(2), 247-263. https://doi.org/10.1002/2013jf002934

Using a one-dimensional numerical model of ice-stream flow with robust grounding-line dynamics, we explore controls on paleo-ice-stream retreat in Marguerite Bay, Antarctica, during the last deglaciation. Landforms on the continental shelf constrain...

Recent retreat of major outlet glaciers on Novaya Zemlya, Russian Arctic, influenced by fjord geometry and sea-ice conditions (2014)
Journal Article
Carr, J., Stokes, C., & Vieli, A. (2014). Recent retreat of major outlet glaciers on Novaya Zemlya, Russian Arctic, influenced by fjord geometry and sea-ice conditions. Journal of Glaciology, 60(219), 155-170. https://doi.org/10.3189/2014jog13j122

Substantial ice loss has occurred in the Russian High Arctic during the past decade, predominantly on Novaya Zemlya, yet the region has been studied relatively little. Consequently, the factors forcing mass loss and the relative contribution of ice d...

Increased channelization of subglacial drainage during deglaciation of the Laurentide Ice Sheet (2014)
Journal Article
Storrar, R., Stokes, C., & Evans, D. (2014). Increased channelization of subglacial drainage during deglaciation of the Laurentide Ice Sheet. Geology, 42(3), 239-242. https://doi.org/10.1130/g35092.1

The configuration of subglacial meltwater is a critical control on ice sheet dynamics, and the presence of pressurized water distributed across the bed can induce dynamic instabilities. However, this process can be offset by efficient evacuation of w... Read More about Increased channelization of subglacial drainage during deglaciation of the Laurentide Ice Sheet.

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.
