Locally grounded features in ice shelves, called ice rises and rumples, play a key role
buttressing discharge from the Antarctic Ice Sheet and regulating its contribution to sea level …

The largest uncertainty in future sea-level rise is loss of ice from the Greenland and Antarctic
Ice Sheets. Ice shelves, freely floating platforms of ice that fringe the ice sheets, play a …

Iceberg calving from all Antarctic ice shelves has never been directly measured, despite
playing a crucial role in ice sheet mass balance. Rapid changes to iceberg calving naturally …

The sudden propagation of a major preexisting rift (full-thickness crack) in late 2016 on the
Larsen C Ice Shelf, Antarctica led to the calving of tabular iceberg A68 in July 2017, one of …

Assessments of the Antarctic contribution to future sea level rise have generally focused on
ice loss in West Antarctica. This focus was motivated by glaciological and oceanographic …

Antarctic ice shelves provide buttressing support to the ice sheet, stabilising the flow of
grounded ice and its contribution to global sea levels. Over the past 50 years, satellite …

Ice shelves control sea-level rise through frictional resistance, which slows the seaward flow
of grounded glacial ice. Evidence from around Antarctica indicates that ice shelves are …

Ice sheet response to forced changes—such as that from anthropogenic climate forcing—is
closely regulated by two‐way interactions with other components of the Earth system. These …

Ice streams flowing into Ross Ice Shelf are presently responsible for around 10% of the
mass flux from West Antarctica, with the noteworthy exception of Kamb Ice Stream, which …

The Larsen B ice shelf collapsed in 2002 losing an area twice the size of Greater London to
the sea (3,000 km2), in an event associated with widespread supraglacial lake drainage …
