A decade of glaciological and meteorological observations in the Arctic (Werenskioldbreen, Svalbard) [PDF]
Earth System Science Data, 2022 Abstract. The warming of the Arctic climate is well documented, but the mechanisms of Arctic amplification are still not fully understood. Thus, monitoring of glaciological and meteorological variables and the environmental response to accelerated climate warming must be continued and developed in Svalbard. Long-term meteorological observations carried

A long-term proxy for sea ice thickness in the Canadian Arctic: 1996–2020 [PDF]
The Cryosphere, 2023 This study presents a long-term winter sea ice thickness proxy product for the Canadian Arctic based on a random forest regression model – applied to ice charts and scatterometer data, trained on CryoSat-2 observations, and applying an ice type–sea ice ...

The Queen of the Arctic: Louise Arner Boyd
Polar Research, 2023 Louise Boyd (1887–1972) was a female pioneer in Arctic research whose legacy includes the exploration of north-east Greenland. In this Perspective piece, we use a broad interdisciplinary approach to investigate her career as a photographer and expedition

Comparing elevation and backscatter retrievals from CryoSat-2 and ICESat-2 over Arctic summer sea ice [PDF]
The Cryosphere, 2023 The CryoSat-2 radar altimeter and ICESat-2 laser altimeter can provide complementary measurements of the freeboard and thickness of Arctic sea ice. However, both sensors face significant challenges for accurately measuring the ice freeboard when the sea ...

Structural evolution during a surge in the Paulabreen glacier system, Svalbard
Journal of Glaciology, 2023 We assess the evolution of glaciological structures during the 2003–05 surge in the Paulabreen glacier system, Svalbard. Glaciological structures on the glacier surface were mapped using aerial photographs captured in the early stages of the surge (2003)

Microstructures in a shear margin: Jarvis Glacier, Alaska
Journal of Glaciology, 2021 Microstructures, including crystallographic fabric, within the margin of streaming ice can exert strong control on flow dynamics. To characterize a natural setting, we retrieved three cores, two of which reached bed, from the flank of Jarvis Glacier ...

The importance of turbulent ocean–sea ice nutrient exchanges for simulation of ice algal biomass and production with CICE6.1 and Icepack 1.2 [PDF]
Geoscientific Model Development, 2022 Different sea ice models apply unique approaches in the computation of nutrient diffusion between the ocean and the ice bottom, which are generally decoupled from the calculation of turbulent heat flux.

The extreme yet transient nature of glacial erosion
Nature Communications, 2022 Glacial erosion processes over geological timescales are poorly understood. Here the authors apply an observationally constrained model to reconstruct the evolving thermodynamics and transient erosional signature of the Eurasian Ice Sheet over the last ...

Steep ice – progress and future challenges in research on ice cliffs
Annals of Glaciology, 2022 Ice cliffs are features along ice sheet margins, along tropical mountain glaciers, at termini of mountain glaciers and on debris-covered glacier tongues, that have received scattered attention in literature.

The influence of a model subglacial lake on ice dynamics and internal layering [PDF]
The Cryosphere, 2016 As ice flows over a subglacial lake, the drop in bed resistance leads to an increase in ice velocities and a draw down of isochrones and cold ice. The ice surface flattens as it adjusts to the lack of resisting forces at the base. The rapid transition in
