Ocean tides are the main source of high‐frequency variability in the vertical and horizontal
motion of ice sheets near their marine margins. Floating ice shelves, which occupy about …

Satellite laser altimetry measures accurate elevations of the Earth's surface and precise
changes with time, monitoring key climate variables. These observations have transformed …

Ocean-driven basal melting of Antarctica's floating ice shelves accounts for about half of
their mass loss in steady state, where gains in ice-shelf mass are balanced by losses. Ice …

A potentially irreversible threshold in Antarctic ice shelf melting would be crossed if the
ocean cavity beneath the large Filchner–Ronne Ice Shelf were to become flooded with warm …

Ocean melting has thinned Antarctica's ice shelves at an increasing rate over the past two
decades, leading to loss of grounded ice. The Ross Ice Shelf is currently close to steady …

Satellite observations over the past two decades have revealed increasing loss of grounded
ice in West Antarctica, associated with floating ice shelves that have been thinning. Thinning …

Ocean-induced melting below ice shelves is one of the dominant drivers for mass loss from
the Antarctic Ice Sheet at present. An appropriate representation of sub-shelf melt rates is …

Ice–ocean interactions at the bases of Antarctic ice shelves are rarely observed, yet have a
profound influence on ice sheet evolution and stability. Ice sheet models are highly sensitive …

Ice loss from the Antarctic ice sheet (AIS) is expected to become the major contributor to sea
level in the next centuries. Projections of the AIS response to climate change based on …

A 63‐year observational record in the southwest Ross Sea shows a continuing, near‐linear
salinity decrease of 0.170 and slight warming of 0.013° C through 2020. That freshening …
