A statistical study of polar cap flow channels observed in both hemispheres using SuperDARN radars

open access: yesJournal of Space Weather and Space Climate, 2022
This paper details the first large-scale, interhemispheric statistical study into ionospheric fast flow (>900 m/s) channels in the polar cap using the SuperDARN radar network.

Electron precipitation characteristics during isolated, compound, and multi-night substorm events [PDF]

open access: yesAnnales Geophysicae, 2021
A set of 24 isolated, 46 compound, and 36 multi-night substorm events from the years 2008–2013 have been analysed in this study. Isolated substorm events are defined as single expansion–recovery phase pairs, compound substorms consist of multiple phase ...

Space and atmospheric physics on Svalbard: a case for continued incoherent scatter radar measurements under the cusp and in the polar cap boundary region

open access: yesProgress in Earth and Planetary Science, 2023
Incoherent scatter radars (ISRs) represent the only instrument (both ground and space based) capable of making high temporal and spatial resolution measurements of multiple atmospheric parameters—such as densities, temperatures, particle velocities, mass

Reconfiguration and closure of lobe flux by reconnection during northward IMF: possible evidence for signatures in cusp/cleft auroral emissions [PDF]

open access: yesAnnales Geophysicae, 1999
Observations are presented of the response of the dayside cusp/cleft aurora to changes in both the clock and elevation angles of the interplanetary magnetic field (IMF) vector, as monitored by the WIND spacecraft.

Auroral all-sky camera calibration [PDF]

open access: yesGeoscientific Instrumentation, Methods and Data Systems, 2014
A two-step procedure to calibrate the spectral sensitivity to visible light of auroral all-sky cameras is outlined. Center pixel response is obtained by the use of a Lambertian surface and a standard 45 W tungsten lamp.

Jupyter Book as an open online teaching environment in the geosciences: lessons learned from Geo-SfM and Geo-UAV [PDF]

open access: yesGeoscience Communication
Together with our students, we co-created two open-access geoscientific course modules using the Jupyter Book environment. We also assessed the Jupyter Book environment, integrated with GitHub to facilitate versioning, for its suitability for co-creation

Relict and contemporary soils on uplifted marine terraces of Kvartsittsletta, SW Spitsbergen [PDF]

open access: yesPolish Polar Research, 2023
The soils of Arctic regions are of great interest due to their high sensitivity to climate change. Kvartsittsletta coast in the vicinity of the Baranowski Research Station of the University of Wrocław constitutes a sequence of differently aged sea ...

An emerging pathway of Atlantic Water to the Barents Sea through the Svalbard Archipelago: drivers and variability [PDF]

open access: yesOcean Science
The Barents Sea, an important component of the Arctic Ocean, is experiencing changes in its ocean currents, stratification, sea ice variability, and marine ecosystems. Inflowing Atlantic Water (AW) is a key driver of these changes.

Conceptual model for talus slope development in Brattegg Valley (SW Spitsbergen) based on sedimentology of debris deposits in periglacial zone [PDF]

open access: yesPolish Polar Research, 2023
The talus slopes occur in all climatic zones on the Earth. These forms are sensitive to climate fluctuations, therefore they may be indicators of changes in the environment and contain the record of the geomorphological events after the deglaciation ...
