The stability of ice sheets and their contributions to sea level are modulated by high-
pressure water that lubricates the base of the ice, facilitating rapid flow into the ocean. In …

The flow of water beneath the Antarctic Ice Sheet has recently been shown to involve
drainage from and exchange between subglacial lakes, with flow routing over distances of> …

Outburst floods from subglacial lakes beneath the Antarctic Ice Sheet modulate ice-flow
velocities over periods of months to years. Although subglacial lake drainage events have …

Basal hydrological systems play an important role in controlling the dynamic behaviour of
ice streams. Data showing their morphology and relationship to geological substrates …

Deep beneath the thick ice cover of the Antarctic continent there exist subglacial
hydrological networks, within which basal meltwater can flow. In this paper, we use surface …

Subglacial hydrology is critical to understand the behaviour of ice sheets, yet active
meltwater drainage beneath contemporary ice sheets is rarely accessible to direct …

In the coming decades, significant changes in the polar regions will increase the contribution
of ice sheets to global sea-level rise. Under the ice streams and outlet glaciers that deliver …

Antarctica's fast-flowing ice streams drain the ice sheet, with their velocity modulated by
subglacial water systems. Current knowledge of these water systems is limited to the …

Antarctica preserves Earth's largest ice-sheet, which in response to climate warming, may
lose ice mass and raise sea level by several metres. The ice-sheet bed exerts critical …

It is now well documented that over 400 subglacial lakes exist across the bed of the Antarctic
Ice Sheet. They comprise a variety of sizes and volumes (from the approx. 250 km long Lake …
