Abstract A large volume of the East Antarctic Ice Sheet drains through the Totten Glacier (TG) and is thought to be a potential source of substantial global sea-level rise over the coming centuries. We show that the surface velocity and height of the floating part of the TG, which buttresses the grounded component, have varied substantially over two decades (1989–2011), with variations in surface height strongly anti-correlated with simulated basal melt rates (r = 0.70, p < 0.05). Coupled…

Widespread Grounding Line Retreat of Totten Glacier, East Antarctica, Over the 21st Century
Totten Glacier (TG), the primary ice discharger of East Antarctica, contains 3.85 m sea level rise equivalent (SLRe) ice mass and has displayed ocean‐driven dynamic change since at least the early…
Wind causes Totten Ice Shelf melt and acceleration
TLDR
The results establish a link between the stability of Totten Glacier and upwelling near the East Antarctic coast, where surface winds are projected to intensify over the next century as a result of increasing atmospheric greenhouse gas concentrations.
The Impact of Variable Ocean Temperatures on Totten Glacier Stability and Discharge
A major uncertainty in Antarctica's contribution to future sea‐level rise is the ice sheet response timescales to ocean warming. Totten Glacier drains a region containing 3.9 m global sea level…
Antarctic Slope Current Modulates Ocean Heat Intrusions Towards Totten Glacier
The Totten ice shelf (TIS) in East Antarctica has received increasing attention in recent years due to high basal melt rates, which have been linked to a presence of warm modified Circumpolar Deep…
Imminent calving accelerated by increased instability of the Brunt Ice Shelf, in response to climate warming
Modelled fracture and calving on the Totten Ice Shelf
Abstract. The Totten Ice Shelf (IS) has a large drainage basin, much of which is grounded below sea level, leaving the glacier vulnerable to retreat through the marine ice sheet instability…

Exploration of subsurface Antarctica: uncovering past changes and modern processes
Abstract The Antarctic continent, which contains enough ice to raise sea level globally by around 60 m, is the last major scientific frontier on our planet. We know far more about the surfaces of the…

Antarctic ice-sheet loss driven by basal melting of ice shelves
TLDR
Satellite laser altimetry and modelling of the surface firn layer are used to reveal the circum-Antarctic pattern of ice-shelf thinning through increased basal melt, which implies that climate forcing through changing winds influences Antarctic ice-sheet mass balance, and hence global sea level, on annual to decadal timescales.
Repeated large-scale retreat and advance of Totten Glacier indicated by inland bed erosion
TLDR
Demarcate the marginal zones of two distinct quasi-stable EAIS configurations, corresponding to the ‘modern-scale’ ice sheet and the retreated ice sheet, suggesting shorter-lived exposure to eroding conditions during repeated retreat–advance events, which are probably driven by ocean-forced instabilities.
Extensive dynamic thinning on the margins of the Greenland and Antarctic ice sheets
Many glaciers along the margins of the Greenland and Antarctic ice sheets are accelerating and, for this reason, contribute increasingly to global sea-level rise. Globally, ice losses contribute ∼1.8…
Variability of basal melt beneath the Pine Island Glacier ice shelf, West Antarctica

Modeling the basal melting and marine ice accretion of the Amery Ice Shelf
The basal mass balance of the Amery Ice Shelf (AIS) in East Antarctica is investigated using a numerical ocean model. The main improvements of this model over previous studies are the inclusion of…
Ice flow dynamics and mass loss of Totten Glacier, East Antarctica, from 1989 to 2015
Totten Glacier has the largest ice discharge in East Antarctica and a basin grounded mostly below sea level. Satellite altimetry data have revealed ice thinning in areas of fast flow. Here we present…

Abstract The East Antarctic ice sheet (EAIS) is Earth’s largest reservoir of fresh water and has the potential to raise sea level by ~50 m. A significant amount of the ice sheet’s mass is discharged…
