Passive seismic recording of cryoseisms in Adventdalen, Svalbard
(Journal article; Peer reviewed, 2021)A series of transient seismic events were discovered in passive seismic recordings from 2-D geophone arrays deployed at a frost polygon site in Adventdalen, Svalbard. These events contain a high proportion of surface wave ... -
Pervasive cold ice within a temperate glacier – implications for glacier thermal regimes, sediment transport and foreland geomorphology.
(Peer reviewed; Journal article, 2019-03-07)This study suggests that cold-ice processes may be more widespread than previously assumed, even within temperate glacial systems. We present the first systematic mapping of cold ice at the snout of the temperate glacier ... -
Rapid sea ice changes in the future Barents Sea
(Journal article; Peer reviewed, 2023)Observed and future winter Arctic sea ice loss is strongest in the Barents Sea. However, the anthropogenic signal of the sea ice decline is superimposed by pronounced internal variability that represents a large source of ... -
Record summer rains in 2019 led to massive loss of surface and cave ice in SE Europe
(Journal article; Peer reviewed, 2021)Glaciers worldwide are shrinking at an accelerated rate as the climate changes in response to anthropogenic influence. While increasing air temperature is the main factor behind glacier mass and volume loss, variable ... -
Robust uncertainty assessment of the spatio-temporal transferability of glacier mass and energy balance models
(Peer reviewed; Journal article, 2019-02-08)Energy and mass-balance modelling of glaciers is a key tool for climate impact studies of future glacier behaviour. By incorporating many of the physical processes responsible for surface accumulation and ablation, they ... -
The role of sublimation as a driver of climate signals in the water isotope content of surface snow: Laboratory and field experimental results
(Journal article; Peer reviewed, 2021)Ice core water isotope records from Greenland and Antarctica are a valuable proxy for paleoclimate reconstruction, yet the processes influencing the climate signal stored in the isotopic composition of the snow are being ... -
Sea ice thickness from air-coupled flexural waves
(Journal article; Peer reviewed, 2021)Air-coupled flexural waves (ACFWs) appear as wave trains of constant frequency that arrive in advance of the direct air wave from an impulsive source travelling over a floating ice sheet. The frequency of these waves varies ... -
Sensitivity of the Greenland surface mass and energy balance to uncertainties in key model parameters
(Journal article; Peer reviewed, 2021)We investigate the sensitivity of a distributed glacier surface mass and energy balance model using a variance-based analysis, for two distinct periods of the last glacial cycle: the present day (PD) and the Last Glacial ... -
Simulated retreat of Jakobshavn Isbræ since the Little Ice Age controlled by geometry
(Peer reviewed; Journal article, 2018-07-12)Rapid retreat of Greenland's marine-terminating glaciers coincides with regional warming trends, which have broadly been used to explain these rapid changes. However, outlet glaciers within similar climate regimes ... -

Simulating the evolution of Hardangerjøkulen ice cap in southern Norway since the mid-Holocene and its sensitivity to climate change
(Peer reviewed; Journal article, 2017-01-27)Understanding of long-term dynamics of glaciers and ice caps is vital to assess their recent and future changes, yet few long-term reconstructions using ice flow models exist. Here we present simulations of the maritime ... -
Sources of uncertainty in Greenland surface mass balance in the 21st century
(Journal article; Peer reviewed, 2022)The surface mass balance (SMB) of the Greenland ice sheet is subject to considerable uncertainties that complicate predictions of sea level rise caused by climate change. We examine the SMB of the Greenland ice sheet in ... -
Uncertainties in Arctic sea ice thickness and volume: new estimates and implications for trends
(Peer reviewed; Journal article, 2014-04-22)Sea ice volume has decreased in the last decades, evoked by changes in sea ice area and thickness. Estimates of sea ice area and thickness rely on a number of geophysical parameters which introduce large uncertainties. To ... -
Waveform classification of airborne synthetic aperture radar altimeter over Arctic sea ice
(Peer reviewed; Journal article, 2013-08-19)Sea ice thickness is one of the most sensitive variables in the Arctic climate system. In order to quantify changes in sea ice thickness, CryoSat-2 was launched in 2010 carrying a Ku-band radar altimeter (SIRAL) designed ...
