Subglacial processes on an Antarctic ice stream bed. 2: Can modelled ice dynamics explain the morphology of mega-scale glacial lineations?. Journal of Glaciology, 62(232), 285-298. https://doi.org/10.1017/jog.2016.19

Mega-scale glacial lineations (MSGLs) are highly elongate subglacial bedforms associated with ice streaming. However, the link between MSGLs and rapid ice flow is largely qualitative, and there have been few attempts to quantitatively link their form...

Ice stream motion facilitated by a shallow-deforming and accreting bed (2016)
Journal Article
Spagnolo, M., Phillips, E., Piotrowski, J., Rea, B., Clark, C., Stokes, C., …Szuman, I. (2016). Ice stream motion facilitated by a shallow-deforming and accreting bed. Nature Communications, 7, Article 10723. https://doi.org/10.1038/ncomms10723

Ice streams drain large portions of ice sheets and play a fundamental role in governing their response to atmospheric and oceanic forcing, with implications for sea-level change. The mechanisms that generate ice stream flow remain elusive. Basal slid... Read More about Ice stream motion facilitated by a shallow-deforming and accreting bed.

Ice stream activity scaled to ice sheet volume during Laurentide Ice Sheet deglaciation (2016)
Journal Article
Stokes, C., Margold, M., Clark, C., & Tarasov, L. (2016). Ice stream activity scaled to ice sheet volume during Laurentide Ice Sheet deglaciation. Nature, 530(7590), 322-326. https://doi.org/10.1038/nature16947

The contribution of the Greenland and West Antarctic ice sheets to sea level has increased in recent decades, largely owing to the thinning and retreat of outlet glaciers and ice streams1, 2, 3, 4. This dynamic loss is a serious concern, with some mo... Read More about Ice stream activity scaled to ice sheet volume during Laurentide Ice Sheet deglaciation.

The glacial geomorphology of the Loch Lomond Stadial in Britain: a map and geographic information system resource of published evidence (2016)
Journal Article

The Loch Lomond Stadial (LLS) was an abrupt period of renewed cooling between 12.9 and 11.7 ka and has long been associated with the regrowth of glaciers in much of upland Britain. Mapping the glacial landforms associated with this period has been un...

Understanding the evolution of the ice-bed interface is fundamentally important for gaining insight into the dynamics of ice masses and how subglacial landforms are created. However, the formation of the suite of landforms generated at this boundary... Read More about Do subglacial bedforms comprise a size and shape continuum?.

The timing and extent of former glacial advances can demonstrate leads and lags during 2 periods of climatic change and their forcing, but this requires robust glacial chronologies. In 3 parts of southernmost Patagonia, dating pre-global Last Glacial...
