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 ...

Health risks, emergency preparedness and Norwegian-Russian cooperation on Svalbard. A systematic review

open access: yesInternational Journal of Circumpolar Health, 2022
This is the first systematic review to explore health risks on Svalbard. We have analysed data retrieved from 18 articles that met eligibility criteria and present a mixed-methods quantitative and qualitative narrative synthesis.

First three-dimensional skull of the Middle Triassic mixosaurid ichthyosaur Phalarodon fraasi from Svalbard, Norway [PDF]

open access: yesActa Palaeontologica Polonica, 2022
The marine Middle Triassic sediments of Svalbard are rich in fossiliferous material and are particularly well-known for marine reptile fossils. Here, we present a new specimen of the small-bodied mixosaurid ichthyosaur Phalarodon fraasi from the ...

First ice core records of NO3− stable isotopes from Lomonosovfonna, Svalbard [PDF]

open access: yes, 2014
Samples from two ice cores drilled at Lomonosovfonna, Svalbard, covering the period 1957–2009, and 1650–1995, respectively, were analyzed for NO3− concentrations, and NO3− stable isotopes (δ15N and δ18O).

The Billefjorden Fault Zone north of Spitsbergen: a major terrane boundary?

open access: yesPolar Research, 2021
The Billefjorden Fault Zone is a major terrane boundary in the Norwegian Arctic. The fault separates basement rocks of Svalbard’s north-eastern and north-western terranes that recorded discrete Precambrian tectonothermal histories and were accreted ...

On the contribution of thermal excitation to the total 630.0 nm emissions in the northern cusp ionosphere [PDF]

open access: yes, 2017
Direct impact excitation by precipitating electrons is believed to be the main source of 630.0 nm emissions in the cusp ionosphere. However, this paper investigates a different source, 630.0 emissions caused by thermally excited atomic oxygen O$(^{1}$D ...

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.
