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.

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 ...

Permafrost trapped natural gas in Svalbard, Norway

open access: yesFrontiers in Earth Science, 2023
Permafrost is widespread in the High Arctic, including the Norwegian archipelago of Svalbard. The uppermost permafrost intervals have been well studied, but the processes at its base and the impacts of the underlying geology have been largely overlooked.

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 ...

Interannual and Decadal Variability of Sea Surface Temperature and Sea Ice Concentration in the Barents Sea

open access: yesRemote Sensing, 2022
Sea ice loss and accelerated warming in the Barents Sea have recently been one of the main concerns of climate research. In this study, we investigated the trends and possible relationships between sea surface temperature (SST), sea ice concentration ...

Scientific Applications of Unmanned Vehicles in Svalbard (UAV Svalbard)

open access: yes, 2021
This is chapter 3 of the State of Environmental Science in Svalbard (SESS) report 2020 (https://sios-svalbard.org/SESS_Issue3). The polar regions are among the most sensitive areas of the Earth and changes in the Arctic have global consequences. Therefore, more and better Arctic research is needed, and unmanned vehicles are an important tool in this ...

Permafrost Base Degradation: Characteristics and Unknown Thread With Specific Example From Hornsund, Svalbard

open access: yesFrontiers in Earth Science, 2022
Permafrost degradation is one of the most pressing issues in the modern cryosphere related to climate change. Most attention is paid to the degradation of the top of the active permafrost associated with contemporary climate.

Suppression of the dayside magnetopause surface modes

open access: yesSolar-Terrestrial Physics, 2017
Magnetopause surface eigenmodes were suggested as a potential source of dayside high-latitude broadband pulsations in the Pc5-6 band (frequency about 1–2 mHz). However, the search for a ground signature of these modes has not provided encouraging results.
