Are long subglacial bedforms indicative of fast ice flow
It has been suggested that extremely long subglacial bedforms (e.g. attenuated drumlins and mega-scale glacial lineations) record former areas of fast-flowing ice and that bedform elongation ratio isExpand

Ice-stream stability on a reverse bed slope
Marine ice streams whose beds deepen inland are thought to be inherently unstable. Numerical modelling of the Maguerite Bay ice-stream retreat in West Antarctica since the Last Glacial MaximumExpand

Ice stream activity scaled to ice sheet volume during Laurentide Ice Sheet deglaciation
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 streams. ThisExpand

Rapid, climate-driven changes in outlet glaciers on the Pacific coast of East Antarctica
Observations of ocean-terminating outlet glaciers in Greenland and West Antarctica indicate that their contribution to sea level is accelerating as a result of increased velocity, thinning andExpand

The instability theory of drumlin formation and its explanation of their varied composition and internal structure.
Despite their importance in understanding glaciological processes and constraining large-scale flow patterns in palaeo-glaciology, there is little consensus as to how drumlins are formed. Attempts toExpand

Threefold increase in marine-terminating outlet glacier retreat rates across the Atlantic Arctic: 1992–2010
Accelerated discharge through marine-terminating outlet glaciers has been a key component of the rapid mass loss from Arctic glaciers since the 1990s. However, glacier retreat and its climatic Expand

A Review of Recent Changes in Major Marine-Terminating Outlet Glaciers in Northern Greenland
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 marineExpand

Subglacial bedforms reveal an exponential size-frequency distribution
Subglacial bedforms preserved in deglaciated landscapes record characteristics of past ice–sediment flow regimes, providing insight into subglacial processes and ice sheet dynamics. Individual formsExpand

Deglaciation of the Laurentide Ice Sheet from the Last Glacial Maximum.
The last deglaciation of the Laurentide Ice Sheet (LIS) was associated with major reorganisations in the ocean-climate system and its retreat also represents a valuable analogue for understanding the rates and mechanisms of ice sheet collapse. Expand

Formation mechanisms for ice-stream lateral shear margin moraines
The lateral shear margins of palaeo-ice stream beds are occasionally marked by large curvilinear moraines, but little work has addressed how they might form. In this paper we review theExpand
