Best practice for peatland restoration in Norway: the expert view
(Master thesis, 2023)Peatlands play an important role in mitigating climate change in Norway, and provide many other ecosystem services. This puts pressure on the success of restoration efforts. The aim of this thesis was to synthesize knowledge ... -
Assessing the impact of land-use on soil carbon stored in deep peat
(Master thesis, 2023)Peatlands accumulate organic material in waterlogged soil and provide stable, long-term storage for carbon. However, peatland carbon stocks are sensitive to disturbance from land-use change and the increase in vascular ... -
Radarundersøkelser av Vanndalsbreen i Jostedalen og vurdering av faren for jøkulhlaup
(Bachelor thesis, 2023)På grunn av stadig økende middeltemperatur og smelting av dagens isbreer kan vi forvente en økning av geofaren jøkulhlaup. Et jøkulhlaup er en plutselig drenering av en glasial innsjø, og kan forårsake store ødeleggelser ... -
Hydrogeologiske og strukturgeologiske undersøkelser ved SIMAS avfallsanlegg i Sogndal kommune
(Bachelor thesis, 2023)I denne oppgaven har vi undersøkt en selvmatende fjellakvifer ved SIMAS avfallsanlegg i Festingdalen i Sogndal kommune. Berggrunnen består i hovedsak av prekambriske dypbergarter og yngre granittganger, og er en del av ... -
Kartlegging av romleg variasjon i snødjupne og undersøking av prosessar som bidreg til akkumulasjon på Skjerdinganebreen vinteren 2021-2022
(Bachelor thesis, 2023)Verda over er det blitt rapportert om tilbaketrekking av fjellbrear, isdekke og snødekke. På bakgrunn av snø si betyding for isbrear si levetid og vekst, er det interessant å undersøke endringar og sesongvariasjon i ... -
Første massebalansemålinger og forbedret istykkelsedata på Skjerdinganebreen
(Bachelor thesis, 2023)Gitt den pågående globale klimasituasjonen og den forventede tilbaketrekningen av isbreer, er formålet med denne oppgaven todelt. Først ble kunnskapen om istykkelsen og volumet til Skjerdinganebreen undersøkt, forbedret ... -
The effect of recent (0-80 years) environmental change on the geochemical (XRF and magnetic susceptibility) record of Lærdalsfjord sediments, Western Norway
(Bachelor thesis, 2023)This thesis reconstructs past environmental change using the geochemical record of two sediment cores the Inner and Outer Lærdalsfjord, Western Norway. Reconstruction of past environmental change of the Lærdalsfjord can ... -
The environmental signal of diatoms in recent (0-90 years) sediments from the Lærdalsfjord, Western Norway
(Bachelor thesis, 2023)Two sediment cores were retrieved from the oxic Inner and Outer Lærdalsfjord, Western Norway. The fossil diatom record of these cores was used to reconstruct environmental and climate change over the past 90 years, providing ... -
The ‘Little Ice Age’ advance of Nigardsbreen, Norway: A cross-disciplinary revision of the chronological framework
(Peer reviewed; Journal article, 2023)This study presents a cross-disciplinary revision of the Little Ice Age (LIA) advance of Nigardsbreen glacier, an outlet from Jostedalsbreen ice cap in western Norway. The associated glacier foreland is characterised by a ... -
Post-Little Ice Age glacial lake evolution in Svalbard: Inventory of lake changes and lake types
(Peer reviewed; Journal article, 2023)The rapid formation of glacial lakes is one of the most conspicuous landscape changes caused by atmospheric warming in glacierised regions. However, relatively little is known about the history and current state of glacial ... -
More warm-adapted species in soil seed banks than in herb layer plant communities across Europe
(Peer reviewed; Journal article, 2023)1. Responses to climate change have often been found to lag behind the rate of warming that has occurred. In addition to dispersal limitation potentially restricting spread at leading range margins, the persistence of ... -
Nest building in titmice Paridae: Selectivity in bryophyte use
(Peer reviewed; Journal article, 2023)In many bird species, reproductive success is dependent on nest quality. However, detailed data on nest composition are scarce, and quantitative analyses have generally used only rough categories, without species identification. ... -

Biogeochemistry of low- and high-centered ice-wedge polygons in wetlands in Svalbard
(Peer reviewed; Journal article, 2023)Arctic wetlands are a globally significant store of soil organic carbon. They are often characterized by ice-wedge polygons, which are diagnostic of lowland permafrost, and which greatly influence wetland hydrology and ... -
Statistical evidence for the contribution of citizen-led initiatives and projects to the energy transition in Europe
(Peer reviewed; Journal article, 2023)Statistical accounting of the impacts of citizen-led energy initiatives is absent, despite their impact on increased energy self-sufficiency and ramping up of renewable energies, local sustainable development, greater ... -
Short-term inflow forecasting in a dam-regulated river in Southwest Norway using causal variational mode decomposition
(Peer reviewed; Journal article, 2023)Climate change affects patterns and uncertainties associated with river water regimes, which significantly impact hydropower generation and reservoir storage operation. Hence, reliable and accurate short-term inflow ... -
The dessau grassland experiment-impact of fertilization on forage quality and species assembly in a species-rich alluvial meadow
(Peer reviewed; Journal article, 2021)Since alluvial meadows of river valleys of the Cnidion dubii are protected by the EU Habitats Directive, reconciling farmers’ demands for forage quality with the objective of maintaining them in good conservation status ... -
A Europe-wide inventory of citizen-led energy action with data from 29 countries and over 10000 initiatives
(Peer reviewed; Journal article, 2023)Numerous case studies show that citizens engage in various ways in renewable and low carbon energy projects, thereby contributing to the sustainable energy transition. To date, however, a systematic and cross-country ... -
