Melting is pervasive along the ice surrounding Antarctica. On the surface of the grounded ice
sheet and floating ice shelves, extensive networks of lakes, streams and rivers both store …

Government policies currently commit us to surface warming of three to four degrees Celsius
above pre-industrial levels by 2100, which will lead to enhanced ice-sheet melt. Ice-sheet …

The calving of A‐68, the 5,800‐km2, 1‐trillion‐ton iceberg shed from the Larsen C Ice Shelf
in July 2017, is one of over 10 significant ice‐shelf loss events in the past few decades …

The climate in Svalbard is undergoing amplified change compared to the global mean. This
has major implications for runoff from glaciers and seasonal snow on land. We use a …

Surface meltwater on ice shelves can be stored as slush, in melt ponds, in surface streams
and rivers, and may also fill crevasses. The collapse of the Larsen B Ice Shelf in 2002 has …

Antarctic supraglacial lakes (SGLs) have been linked to ice shelf collapse and the
subsequent acceleration of inland ice flow, but observations of SGLs remain relatively …

The density structure of firn has implications for hydrological and climate modelling, and ice-
shelf stability. The structure of firn can be evaluated from depth models of seismic velocity …

Ice shelf collapse reduces buttressing and enables grounded glaciers to contribute more
rapidly to sea-level rise in a warming climate. The abrupt collapses of the Larsen A (1995) …

Estimates for the recent period and projections of the Antarctic surface mass balance (SMB)
often rely on high-resolution polar-oriented regional climate models (RCMs). However …

Supraglacial lakes are known to trigger Antarctic ice-shelf instability and break-up. However,
to date, no study has focused on lakes on Greenland's floating termini. Here, we apply lake …
