Abstract. We present Bedmap2, a new suite of gridded products describing surface elevation, ice-thickness and the seafloor subglacial bed elevation Antarctic south 60° S. derived these using data from variety sources, including many substantial surveys completed since original Bedmap compilation (Bedmap1) in 2001. In particular, Bedmap2 ice thickness grid is made 25 million measurements, over two orders magnitude more than were used Bedmap1. most parts Antarctica landscape visible much...
Abstract. Two ice-dynamic transitions of the Antarctic ice sheet – boundary grounded features and freely-floating are mapped at 15-m resolution by participants International Polar Year project ASAID using customized software combining Landsat-7 imagery ICESat/GLAS laser altimetry. The is 53 610 km long; 74 % abuts to floating shelves or outlet glaciers, 19 adjacent open sea-ice covered ocean, 7 terminates on land. boundary, called here hydrostatic line, most landward position that expresses...

Abstract Over recent decades outlet glaciers of the Amundsen Sea Embayment (ASE), West Antarctica, have accelerated, thinned, and retreated, are now contributing approximately 10% to global sea level rise. All ASE flow into ice shelves, it is thinning these since 1970s, their ungrounding from “pinning points” that widely held be responsible for triggering glaciers' decline. These changes been linked inflow warm Circumpolar Deep Water (CPDW) onto ASE's continental shelf. CPDW delivery highly...
Abstract The West Antarctic Ice Sheet overlies the Rift System about which, due to comprehensive ice cover, we have only limited and sporadic knowledge of volcanic activity its extent. Improving our understanding subglacial across province is important both for helping constrain how volcanism rifting may influenced ice-sheet growth decay over previous glacial cycles, in light concerns whether enhanced geothermal heat fluxes melting contribute instability Sheet. Here, use bed-elevation data...
Abstract Radar sounding is a powerful geophysical approach for characterizing the subsurface conditions of terrestrial and planetary ice masses at local to global scales. As result, wide array orbital, airborne, ground-based, in situ instruments, platforms data analysis approaches radioglaciology have been developed, applied or proposed. Terrestrially, airborne radar has used glaciology observe thickness, basal topography englacial layers five decades. More recently, also exploited estimate...
Abstract Ice shelves play a vital role in regulating loss of grounded ice and supplying freshwater to coastal seas. However, melt variability within is poorly constrained may be instrumental driving shelf imbalance collapse. High‐resolution altimetry measurements from 2010 2016 show that Dotson Shelf (DIS), West Antarctica, thins response basal melting focused along single 5 km‐wide 60 km‐long channel extending the shelf's grounding zone its calving front. If thinning continues at present...
Abstract. One of the key components this research has been mapping Antarctic bed topography and ice thickness parameters that are crucial for modelling flow hence predicting future loss ensuing sea level rise. Supported by Scientific Committee on Research (SCAR), Bedmap3 Action Group aims not only to produce new gridded maps international scientific community, but also standardize make available all geophysical survey data points used in producing Bedmap products. Here, we document latest...
Abstract Mass loss of the Antarctic Ice Sheet has been driven primarily by thinning floating ice shelves that fringe sheet 1 , reducing their buttressing potential and causing land to accelerate into ocean 2 . Observations ice-shelf thickness change satellite altimetry stretch back only 1992 (refs. 1,3–5 ) previous information about remains unquantified. However, extending record is possible proxy, measuring in area surface expression pinning points—local bathymetric highs on which are...
The retreating Pine Island Glacier (PIG), West Antarctica, presently contributes ~5-10% of global sea-level rise. PIG's retreat rate has increased in recent decades with associated thinning migrating upstream into tributaries feeding the main glacier trunk. To project future change requires modelling that includes robust parameterisation basal traction, resistance to ice flow at bed. However, most ice-sheet models estimate traction from satellite-derived surface velocity, without a priori...
Abstract Changes to the grounding line, where grounded ice starts float, can be used as a remotely sensed measure of ice‐sheet susceptibility ocean‐forced dynamic thinning. Constraining this is vital for predicting Antarctica's contribution rising sea levels. We use Landsat imagery monitor line movement over four decades along Bellingshausen margin West Antarctica, an area little monitored despite potential future losses. show that ~65% retreated from 1990 2015, with pervasive and...
The Canadian Arctic Archipelago contains >300 glaciers that terminate in the ocean, but little is known about changes their frontal positions response to recent ocean-climate system. Here, we examine glacier since 1950s and investigate relative influence of oceanic temperature versus atmospheric temperature. Over 94% retreated between 1958 2015, with a region-wide trend gradual retreat before ~2000, followed by fivefold increase rates up 2015. Retreat patterns show no correlation subsurface...
Meltwater from the glaciers in High Mountain Asia plays a critical role water availability and food security central southern Asia. However, observations of glacier ablation accumulation rates are limited spatial temporal scale due to challenges that associated with fieldwork at remote, high-altitude settings these glaciers. Here, using remote-sensing-based mass-continuity approach, we compute regional-scale surface mass balance five key regions across After accounting for ice flow, find...
Abstract In this study, we compare equilibrium-line altitudes (ELAs) calculated using the area–altitude balance ratio (AABR) and accumulation–area (AAR) methods, with measured ELAs derived from direct field observations. We utilise a GIS toolbox to calculate ELA for 64 extant glaciers by applying AABR AAR methods DEMs polygons of their geometry. The (c-ELAs) are then compared zero-net (znb-ELAs) obtained mass-balance time series held WGMS same glaciers. correlation between znb-ELAs...
Abstract. Pine Island Glacier, Antarctica, has been undergoing several related changes for at least two decades; these include acceleration, thinning and grounding line retreat. During the first major ground-based study between 2006 2008, GPS receivers were used to monitor ice flow from 55 km 171 inland, along central flowline. At four sites both acceleration rates over last years exceeded observed any other time decades. downstream site was 6.4% 2007 3.5±0.5 ma−1. Acceleration have spread...
We interpret seismic reflection and airborne potential field data acquired on Pine Island Glacier, West Antarctica find variations in the subglacial geology which correlate with ice dynamics. Immediately beneath glacier is a mixture of soft, deforming sediments harder, non‐deforming sediments. Beneath this, sedimentary basin lies under part main glacier, another one its slower‐moving tributaries. A tectonic boundary underlies trunk separating these basins to north from crystalline rocks...

The West Antarctic ice sheet (WAIS) has long been considered vulnerable to rapid retreat and today parts are rapidly losing ice.Projection of future change in WAIS is, however, hampered by our poor understanding past changes, especially during interglacial periods that could be analogs for the future, but which undoubtedly provide an opportunity testing predictive models.We consider how ice-loss would open seaways across WAIS; these likely alter Southern Ocean circulation climate, broadly...
Abstract. Repeat-pass ICESat altimetry has revealed 124 discrete surface height changes across the Antarctic Ice Sheet, interpreted to be caused by subglacial lake discharges (surface lowering) and inputs uplift). Few of these active lakes have been confirmed radio-echo sounding (RES) despite several attempts (notable exceptions are Lake Whillans three in Adventure Subglacial Trench). Here we present targeted RES radar altimeter data from an "active lake" location within upstream Institute...
