Levels and distribution profiles of Per- and Polyfluoroalkyl Substances (PFAS) in a high Arctic Svalbard ice core
(Peer reviewed; Journal article, 2023)Per- and polyfluoroalkyl substances (PFAS) are a group of persistent organic contaminants of which some are toxic and bioaccumulative. Several PFAS can be formed from the atmospheric degradation of precursors such as ... -
Deep-water trace fossils in the Ilfjellet rift basin (Middle Ordovician), central Norwegian Caledonides
(Peer reviewed; Journal article, 2022)The late Early to early Middle Ordovician Fjellvollen Formation, Central Norwegian Caledonides, is a part of the Ilfjellet Group volcano-sedimentary succession formed in a rift basin that opened along the Laurentian margin. ... -
SEM-EDS and water chemistry characteristics at the early stages of glacier recession reveal biogeochemical coupling between proglacial sediments and meltwater
(Peer reviewed; Journal article, 2022)Most glaciers worldwide are undergoing climate-forced recession, but the impact of glacier changes on biogeochemical cycles is unclear. This study examines the influence of proglacial sediment weathering on meltwater ... -
Repeated survey along the foreland of a receding Norwegian glacier reveals shifts in succession of beetles and spiders
(Peer reviewed; Journal article, 2022)Glacier forelands provide important sites to study climate-forced ecological succession because a chronosequence is apparent along a single valley. However, most studies of invertebrate succession in forelands provide a ... -
Grassland plant and invertebrate species richness increases from mowing are mediated by impacts on soil chemistry
(Peer reviewed; Journal article, 2022)Pasture and improved grasslands are commonly managed by a combination of artificial fertilisation and biomass removal, but a deeper understanding of how management options interact over the long-term are required to improve ... -
Stratigraphy and age of a Neoglacial sedimentary succession of proglacial outwash and an alluvial fan in Langedalen, Veitastrond, western Norway
(Peer reviewed; Journal article, 2022)This study presents the sedimentary succession of an outwash plain and an alluvial fan located along the valley Langedalen at the south-eastern side of the Jostedalsbreen ice cap in inner Sogn, western Norway. A newly ... -
Cryoconite – From minerals and organic matter to bioengineered sediments on glacier's surfaces
(Peer reviewed; Journal article, 2022)Cryoconite is a mixture of mineral and organic material covering glacial ice, playing important roles in biogeochemical cycles and lowering the albedo of a glacier surface. Understanding the differences in structure of ... -
Spatially consistent microbial biomass and future cellular carbon release from melting Northern Hemisphere glacier surfaces
(Peer reviewed; Journal article, 2022)Melting glacier ice surfaces host active microbial communities that enhance glacial melt, contribute to biogeochemical cycling, and nourish downstream ecosystems; but these communities remain poorly characterised. Over the ... -
Emergence of new industries in peripheral regions: the role of narratives in delegitimation of onshore wind in the Arctic Finnmark region
(Peer reviewed; Journal article, 2022)This paper discusses how narratives influence the legitimation of new industries in peripheral regions. We contribute to the literature a discussion of the emergence of green industries in peripheral regions, but particularly ... -
The Development of Citizen-Installed Renewable Energy Capacities in Former Eastern Bloc Countries—The Case of Poland
(Peer reviewed; Journal article, 2022)We confront empirical data on citizen-led renewable energy capacities in Poland with results obtained from a meta-theoretical, empirical analysis of the national energy system. We elicit and rank essential disabling and ... -
The brittle evolution of Western Norway – A space-time model based on fault mineralizations, K–Ar fault gouge dating and paleostress analysis
(Peer reviewed; Journal article, 2022)Basement fracture and fault patterns on passive continental margins control the onshore landscape and offshore distribution of sediment packages and fluid pathways. In this study, we decipher the spatial-temporal evolution ... -
A reconstruction of Jostedalsbreen during the Little Ice Age and geometric changes to outlet glaciers since then
(Peer reviewed; Journal article, 2022)Mountain glaciers and ice caps are undergoing rapid mass loss but rates of present-day changes and models of future projections both lack long-term (centennial-scale) context. Here, we reconstruct the maximum glacier extent ... -
Globally elevated chemical weathering rates beneath glaciers
(Peer reviewed; Journal article, 2022)Physical erosion and chemical weathering rates beneath glaciers are expected to increase in a warming climate with enhanced melting but are poorly constrained. We present a global dataset of cations in meltwaters of 77 ... -
POLLINATOR-FLOWER INTERACTIONS IN GARDENS DURING THE COVID-19 PANDEMIC LOCKDOWN OF 2020
(Peer reviewed; Journal article, 2022)During the main COVID-19 global pandemic lockdown period of 2020 an impromptu set of pollination ecologists came together via social media and personal contacts to carry out standardised surveys of the flower visits and ... -
Time-lapse photogrammetry reveals hydrological controls of fine-scale High-Arctic glacier surface roughness evolution
(Peer reviewed; Journal article, 2022)In a warming Arctic, as glacier snowlines rise, short- to medium-term increases in seasonal bare-ice extent are forecast for the next few decades. These changes will enhance the importance of turbulent energy fluxes for ... -
Microbial iron reduction and greenhouse gas production in response to organic matter amendment and temperature increase of periglacial sediments, Bolterdalen, Svalbard
(Peer reviewed; Journal article, 2022)Arctic permafrost soils store substantial reserves of organic matter (OM) from which microbial transformation contributes significantly to greenhouse gas emissions of CH4 and CO2. However, many younger sediments exposed ... -
Extreme precipitation induced landslide event on 30 July 2019 in Jølster, western Norway
(Peer reviewed; Journal article, 2022)A torrential rain event struck western Norway on Tuesday 30 July 2019. Most severely affected was the Jølster community, where numerous landslides and floods damaged public infrastructure and private property. This resulted ... -
Referanser og overvåkingsindikatorer innen økologisk restaurering av verneverdig kulturmark
(Master thesis, 2022)Økologisk restaurering er et virkemidden for å motvirke tap av biologisk mangfold, men det trengs bedre metoder innen målsetning og overvåking for å vite at utviklingen går rett vei. Semi-naturlige naturtyper i Norge er i ... -
Mapping of the Subglacial Topography of Folgefonna Ice Cap in Western Norway—Consequences for Ice Retreat Patterns and Hydrological Changes
(Peer reviewed; Journal article, 2022)Folgefonna consists of three ice caps which are rapidly retreating in response to warmer temperatures. The melting of Folgefonna has implications for meltwater drainage and hydropower production, as well as the potential ...
