Journal Article
Miles, B., Stokes, C., & Jamieson, S. (2017). Simultaneous disintegration of outlet glaciers in Porpoise Bay (Wilkes Land), East Antarctica, driven by sea ice break-up. The Cryosphere, 11, 427-442. https://doi.org/10.5194/tc-11-427-2017

The floating ice shelves and glacier tongues which fringe the Antarctic continent are important because they help buttress ice flow from the ice sheet interior. Dynamic feedbacks associated with glacier calving have the potential to reduce buttressin...

A review of recent changes in major marine-terminating outlet glaciers in northern Greenland (2017)
Journal Article
Hill, E., Carr, R., & Stokes, C. (2017). A review of recent changes in major marine-terminating outlet glaciers in northern Greenland. Frontiers in Earth Science, 4, Article 11. https://doi.org/10.3389/feart.2016.00111

Over the past two decades, mass loss from the Greenland Ice Sheet (GrIS) has accelerated and contributed to global sea level rise. This has been partly attributed to dynamic changes in marine terminating outlet glaciers. Outlet glaciers at the northe...

The stability of contemporary ice sheets is influenced by the discharge from ice streams - corridors of fast-flowing ice bounded by ice flowing an order of magnitude slower. Reconstructions of palaeo-ice stream dynamics contribute to our understandin...

Dynamics of former ice lobes of the southernmost Patagonian Ice Sheet based on a glacial landsystems approach (2016)
Journal Article

Reconstructions of former ice masses from glacial geomorphology help to constrain the nature and timing of glaciation in relation to climatic forcing. This paper presents a new reconstruction of the glacial history of five ice lobes in southernmost S...

Seasonal evolution of supraglacial lakes on an East Antarctic outlet glacier (2016)
Journal Article
Langley, E., Leeson, A., Stokes, C., & Jamieson, S. (2016). Seasonal evolution of supraglacial lakes on an East Antarctic outlet glacier. Geophysical Research Letters, 43(16), 8563-8571. https://doi.org/10.1002/2016gl069511

Supraglacial lakes are known to influence ice melt and ice flow on the Greenland ice sheet and potentially cause ice shelf disintegration on the Antarctic Peninsula. In East Antarctica, however, our understanding of their behavior and impact is more... Read More about Seasonal evolution of supraglacial lakes on an East Antarctic outlet glacier.

The timing and cause of glacial advances in the southern mid-latitudes during the last glacial cycle based on a synthesis of exposure ages from Patagonia and New Zealand (2016)
Journal Article
Darvill, C., Bentley, M., Stokes, C., & Shulmeister, J. (2016). The timing and cause of glacial advances in the southern mid-latitudes during the last glacial cycle based on a synthesis of exposure ages from Patagonia and New Zealand. Quaternary Science Reviews, 149, 200-214. https://doi.org/10.1016/j.quascirev.2016.07.024

Glacier advances in the southern mid-latitudes during the last glacial cycle (ca. 110–10 ka) were controlled by changes in temperature and precipitation linked to several important ocean-climate systems. As such, the timing of glacial advance and ret...

Subglacial bedforms (drumlins, ribbed moraines, mega-scale glacial lineations) are enigmatic repetitive flow-parallel and flow-transverse landforms common in glaciated landscapes. Their evolution and morphology are a potentially powerful constraint f... Read More about Subglacial bedform morphology controlled by ice speed and sediment thickness.

Exploring Explanations of Subglacial Bedform Sizes Using Statistical Models (2016)
Journal Article

Sediments beneath modern ice sheets exert a key control on their flow, but are largely inaccessible except through geophysics or boreholes. In contrast, palaeo-ice sheet beds are accessible, and typically characterised by numerous bedforms. However,...

Rapidly-flowing ice streams are an important mechanism through which ice sheets lose mass, and much work has been focussed on elucidating the processes that increase or decrease their velocity. Recent work using standard inverse methods has inferred...
