Aerodynamic roughness length of crevassed tidewater glaciers from UAV mapping
(Peer reviewed; Journal article, 2021)The aerodynamic roughness length (z0) is an important parameter in the bulk approach for calculating turbulent fluxes and their contribution to ice melt. However, z0 estimates for heavily crevassed tidewater glaciers are ... -
Brief Communication: Mapping river ice using drones and structure from motion
(Journal article; Peer reviewed, 2018)Twenty-first century snowfall changes over the European Alps are assessed based on high-resolution regional climate model (RCM) data made available through the EURO-CORDEX initiative. Fourteen different combinations of ... -
Linking scales of sea ice surface topography: evaluation of ICESat-2 measurements with coincident helicopter laser scanning during MOSAiC
(Peer reviewed; Journal article, 2023)Information about sea ice surface topography and related deformation is crucial for studies of sea ice mass balance, sea ice modeling, and ship navigation through the ice pack. The Ice, Cloud, and land Elevation Satellite-2 ... -
Nunataks as barriers to ice flow: Implications for palaeo ice sheet reconstructions
(Journal article; Peer reviewed, 2021) -
Observations of preferential summer melt of Arctic sea-ice ridge keels from repeated multibeam sonar surveys
(Peer reviewed; Journal article, 2023)Sea-ice ridges constitute a large fraction of the total Arctic sea-ice area (up to 40 %–50 %); nevertheless, they are the least studied part of the ice pack. Here we investigate sea-ice melt rates using rare, repeated ... -
Pressure and inertia sensing drifters for glacial hydrology flow path measurements
(Peer reviewed; Journal article, 2020)Glacial hydrology plays an important role in the control of glacier dynamics, of sediment transport, and of fjord and proglacial ecosystems. Surface meltwater drains through glaciers via supraglacial, englacial and subglacial ... -
Review article: Inferring permafrost and permafrost thaw in the mountains of the Hindu Kush Himalaya region
(Peer reviewed; Journal article, 2017)The cryosphere reacts sensitively to climate change, as evidenced by the widespread retreat of mountain glaciers. Subsurface ice contained in permafrost is similarly affected by climate change, causing persistent impacts ... -
Revisiting Austfonna, Svalbard, with potential field methods - A new characterization of the bed topography and its physical properties
(Journal article; Peer reviewed, 2020)With hundreds of metres of ice, the bedrock underlying Austfonna, the largest icecap on Svalbard, is hard to characterize in terms of topography and physical properties. Ground-penetrating radar (GPR) measurements supply ... -
Sensitivity of lake ice regimes to climate change in the Nordic region
(Journal article; Peer reviewed, 2014-08-28)A one-dimensional process-based multi-year lake ice model, MyLake, was used to simulate lake ice phenology and annual maximum lake ice thickness for the Nordic region comprising Fennoscandia and the Baltic countries. ... -
Sensitivity of the Antarctic ice sheets to the warming of marine isotope substage 11c
(Peer reviewed; Journal article, 2021)Studying the response of the Antarctic ice sheets during periods when climate conditions were similar to the present can provide important insights into current observed changes and help identify natural drivers of ice ... -
The relation between sea ice thickness and freeboard in the Arctic
(Journal article; Peer reviewed, 2010)Retrieval of Arctic sea ice thickness from CryoSat-2 radar altimeter freeboard data requires observational data to verify the relation between these two variables. In this study in-situ ice and snow data from 689 observation ... -
Topology and spatial-pressure-distribution reconstruction of an englacial channel
(Peer reviewed; Journal article, 2022)Information about glacier hydrology is important for understanding glacier and ice sheet dynamics. However, our knowledge about water pathways and pressure remains limited, as in situ observations are sparse and methods ... -
An X-ray micro-tomographic study of the pore space, permeability and percolation threshold of young sea ice
(Journal article; Peer reviewed, 2021)
