Abstract. The dynamics and mass balance regime of the Austfonna ice cap, the largest glacier on Svalbard, deviates significantly from most other glaciers in the region and is not fully understood. We have compared ICESat laser altimetry, airborne laser altimetry, GNSS surface profiles and radio echo-sounding data to estimate elevation change rates for the periods 1983–2007 and 2002–2008. The data sets indicate a pronounced interior thickening of up to 0.5 m y−1, at the same time as the margins…

Diagnosing the decline in climatic mass balance of glaciers in Svalbard over 1957–2014
Abstract. Estimating the long-term mass balance of the high-Arctic Svalbard archipelago is difficult due to the incomplete geodetic and direct glaciological measurements, both in space and time. To
Variability of the climatic mass balance of Vestfonna ice cap, northeastern Svalbard, 1979-2011
Abstract Vestfonna ice cap, northeastern Svalbard, is one of the largest ice bodies in the European Arctic, but little is known about the evolution of its mass balance. This study presents a
Spread of Svalbard Glacier Mass Loss to Barents Sea Margins Revealed by CryoSat‐2
The Norwegian Arctic archipelago of Svalbard is located in the most rapidly warming area of the Arctic, at the interface of Arctic and Atlantic air and ocean masses. The presence of a large number of
Accelerating glacier mass loss on Franz Josef Land, Russian Arctic
Seasonal speed-up of two outlet glaciers of Austfonna, Svalbard, inferred from continuous GPS measurements
A large part of the ice discharge from ice caps and ice sheets occurs through spatially limited flow units that may operate in a mode of steady flow or cyclic surge behaviour. Changes in the dynamics
Importance of basal processes in simulations of a surging Svalbard outlet glacier
The outlet glacier of Basin 3 (B3) of Austfonna ice cap, Svalbard, is one of the fastest outlet glaciers in Svalbard, and shows dramatic changes since 1995. In addition to previously observed
Svalbard glacier elevation changes and contribution to sea level rise
[1] We compare satellite altimetry from the Ice, Cloud, and Land Elevation Satellite (ICESat, 2003–2007) to older topographic maps and digital elevation models (1965–1990) to calculate long-term
Distributed energy and surface mass balance modeling of Austfonna, Svalbard.
The climatic influence on a large cold/polythermal Arctic ice cap with substantial surface melt was investigated by calculating the surface energy balance (SEB) and subsurface properties. This method
Glacier-surge mechanisms promoted by a hydro-thermodynamic feedback to summer melt
Abstract. Mass loss from glaciers and ice sheets currently accounts for two-thirds of the observed global sea-level rise and has accelerated since the 1990s, coincident with strong atmospheric
The Ice‐Free Topography of Svalbard
We present a first version of the Svalbard ice‐free topography (SVIFT1.0) using a mass conserving approach for mapping glacier ice thickness. SVIFT1.0 is informed by more than 1 million point


Positive mass balance during the late 20th century on Austfonna, Svalbard, revealed using satellite radar interferometry
Abstract Determining whether increasing temperature or precipitation will dominate the cryospheric response to climate change is key to forecasting future sea-level rise. The volume of ice contained
The Dynamics of Austfonna, Nordaustlandet, Svalbard: Surface Velocities, Mass Balance, and Subglacial Melt Water
Glaciological measurements from Austfonna on Nordaustlandet, Svalbard, are needed as a prerequIsIte to mathematical modelling of ice-mass dynamics. Several upper and lower boundary conditions are set
Calibrating a surface mass-balance model for Austfonna ice cap, Svalbard
Abstract Austfonna (8120km2) is by far the largest ice mass in the Svalbard archipelago. There is considerable uncertainty about its current state of balance and its possible response to climate
Iceberg calving flux and mass balance of the Austfonna ice cap on Nordaustlandet, Svalbard
[1] Satellite radar interferometry, 60 MHz airborne ice-penetrating radar data, and visible band satellite imagery were used to calculate the velocity structure, ice thickness, and the changing
Geometry changes on Svalbard glaciers: mass-balance or dynamic response?
Abstract The geometry of glaciers is affected by both the mass balance and the dynamics. We present repeated GPS measurements of longitudinal altitude profiles on three glaciers in Svalbard and show
Recent fluctuations in the extent of the firn area of Austfonna, Svalbard, inferred from GPR
Abstract In spring during 2004–07 we conducted ground-penetrating radar (GPR) measurements on the Austfonna ice cap, Svalbard, with the original aim of mapping the thickness and distribution of

Interpretation of the anomalous growth of Austfonna, Svalbard, a large Arctic ice cap
Abstract As previously reported, repeat-pass airborne laser altimetry measurements made in May 1996 and May 2002 show a large positive ice-surface elevation change rate over parts of the accumulation
Elevation changes measured on Svalbard glaciers and ice caps from airborne laser data
Abstract Precise airborne laser surveys were conducted during spring in 1996 and 2002 on 17 ice caps and glaciers in the Svalbard archipelago covering the islands of Spitsbergen and Nordaustlandet.
Acceleration in thinning rate on western Svalbard glaciers
Geodetic measurements indicate that a number of glaciers in western Svalbard ranging in size from 5–1000 km2 are losing mass at an accelerating rate. The average thinning rate for Midtre Lovénbreen,
