The Dynamics of Profitability among Salmon Farmers—A Highly Volatile and Highly Profitable Sector
(Peer reviewed; Journal article, 2022)Salmon farming stands out from many other industries with its very high profitability, but it is also highly volatile. The main question is whether the profit of individual firms is stable, or whether profitable firms ... -
Multi-Temporal Satellite Image Composites in Google Earth Engine for Improved Landslide Visibility: A Case Study of a Glacial Landscape
(Peer reviewed; Journal article, 2022)Regional early warning systems for landslides rely on historic data to forecast future events and to verify and improve alarms. However, databases of landslide events are often spatially biased towards roads or other ... -
Diatoms as proxies for recent (0-20 years) environmental change as recorded in Inner Nærøyfjord sediments, Western Norway
(Bachelor thesis, 2022)Three sediment cores, retrieved at three different stations in the inner Nærøyfjord, Western Norway, are analysed for their diatom assemblage. The dating of the cores is based on the distribution of coarse silt, the ... -
Junipers enable heavily browsed rowan saplings to escape ungulates in boreal forest
(Peer reviewed; Journal article, 2021)Recent increases in ungulate herbivore populations have intensified browsing pressure in northern forest ecosystems. High browsing pressure affects recruitment into tree populations and saplings are among the most impacted ... -
Seismic and electrical geophysical characterization of an incipient coastal open-system pingo: Lagoon Pingo, Svalbard
(Peer reviewed; Journal article, 2021)Whilst there has been a recent appreciation for the role of open-system pingos in providing a fluid-flow conduit through continuous permafrost that enables methane release, the formation and internal structure of these ... -
Unpacking democracy: The effects of different democratic qualities on climate change performance over time
(Peer reviewed; Journal article, 2021)Given democracies’ moderate success in combatting climate change, some have questioned whether democracy makes it harder, not easier, to reduce greenhouse gas emissions. Two decades of research, however, has not provided ... -
På villplantejakt i hagen
(Peer reviewed; Journal article, 2021)Private gardens represent important green infrastructure and include a range of habitats (e.g. lawns, flowerbeds and greenbelts), but little focus has been paid to the role of their spontaneously occurring flora for ... -
Greening of regional industrial paths and the role of sectoral characteristics: A study of the maritime and petroleum sectors in an Arctic region
(Peer reviewed; Journal article, 2021)Recent studies on regional industrial path development call for new perspectives and studies of how a region’s endogenous and exogenous processes (e.g. networks, capital, knowledge) influence its industries, and more ... -
Groundwater fluctuations during a debris flow event in western Norway - triggered by rain and snowmelt
(Peer reviewed; Journal article, 2021)Pore pressure is crucial in triggering debris slides and flows. Here we present measurements of groundwater pore pressure and temperature recorded by a piezometer 1.6 m below the surface on a slope susceptible to debris ... -
Aerodynamic roughness length of crevassed tidewater glaciers from UAV mapping
(Peer reviewed; Journal article, 2021)The aerodynamic roughness length (z_0) is an important parameter in the bulk approach for calculating turbulent fluxes and their contribution to ice melt. However, z_0 estimates for heavily crevassed tidewater glaciers are ... -
Drainage system and thermal structure of a High Arctic polythermal glacier: Waldemarbreen, western Svalbard
(Peer reviewed; Journal article, 2021)Understanding glacier drainage system behaviour and its response to increased meltwater production faces several challenges in the High Arctic because many glaciers are transitioning from polythermal to almost entirely ... -
Field boundary features can stabilise bee populations and the pollination of mass-flowering crops in rotational systems
(Peer reviewed; Journal article, 2021)Pollinators experience large spatiotemporal fluctuations in resource availability when mass-flowering crops are rotated with resource-poor cereal crops. Yet, few studies have considered the effect this has on pollinator ... -
The dynamics of the profitability and growth of restaurants: the case of Norway
(Peer reviewed; Journal article, 2022)The restaurant industry is quite similar across borders. It is a labour-intensive industry that is important for tourism and employment. It consists mainly of many small businesses that are regionally dispersed. There are ... -
Modelling of the gas hydrate potential in Svalbard's fjords
(Peer reviewed; Journal article, 2021)Large amounts of methane are trapped as natural gas hydrate (NGH) in the sediments of the Arctic. Unlike NGH provinces offshore west of Svalbard (Vestnesa Ridge), NGH potential in Svalbard’s fjords and near-shore environment ... -
Groundwater Flow Through Continuous Permafrost Along Geological Boundary Revealed by Electrical Resistivity Tomography
(Peer reviewed; Journal article, 2021)In continuous permafrost regions, pathways for transport of sub-permafrost groundwater to the surface sometimes perforate the frozen ground and result in the formation of a pingo. Explanations offered for the locations of ... -
Concurrent MORB-type and ultrapotassic volcanism in an extensional basin along the Laurentian Iapetus margin: Tectonomagmatic response to Ordovician arc-continent collision and subduction polarity flip
(Peer reviewed; Journal article, 2021)Arc-continent collision, followed by subduction polarity flip, occurs during closure of oceanic basins and contributes to the growth of continental crust. Such a setting may lead to a highly unusual association of ultrapotassic ... -
The seasonal dynamics of a High Arctic plant–visitor network: temporal observations and responses to delayed snow melt
(Peer reviewed; Journal article, 2021)Plant–visitor food webs provide important insights into species interactions, and more information about their seasonal dynamics is vital to understanding the resilience of species to external pressures. Studies of Arctic ... -
Temporal Variability of Surface Reflectance Supersedes Spatial Resolution in Defining Greenland’s Bare-Ice Albedo
(Peer reviewed; Journal article, 2022)Ice surface albedo is a primary modulator of melt and runoff, yet our understanding of how reflectance varies over time across the Greenland Ice Sheet remains poor. This is due to a disconnect between point or transect ... -
MetaComNet: A random forest-based framework for making spatial predictions of plant-pollinator interactions
(Peer reviewed; Journal article, 2021)Predicting plant–pollinator interaction networks over space and time will improve our understanding of how environmental change is likely to impact the functioning of ecosystems. Here we propose a framework for producing ... -
Beyond democracy: Assessing the effect of democratic qualities on CO2
(Master thesis, 2019)Democracy is the preferred system of government when social and economic development is the goal, but what is the effect of democratization on climate change mitigation? Two decades of research into this question has so ...
