Food web functions and interactions during spring and summer in the arctic water inflow region: Investigated through inverse modeling
(Peer reviewed; Journal article, 2019-05-28)We used inverse modeling to reconstruct major planktonic food web carbon flows in the Atlantic Water inflow, east and north of Svalbard during spring (18–25 May) and summer (9–13 August), 2014. The model was based on three ... -
Hemipelagic deposits on the Mendeleev and northwestern Alpha submarine Ridges in the Arctic Ocean: acoustic stratigraphy, depositional environment and an inter-ridge correlation calibrated by the ACEX results
(Peer reviewed; Journal article, 2010)The first high resolution multichannel seismic data from the Mendeleev and Alpha Ridges in the Arctic Ocean have been used to investigate the depositional history, and compare acoustic stratigraphies of the three main ... -
Holocene multi-proxy environmental reconstruction from lake Hakluytvatnet, Amsterdamøya Island, Svalbard (79.5°N)
(Journal article, 2018-03)High resolution proxy records of past climate are sparse in the Arctic due to low organic production that restricts the use of radiocarbon dating and challenging logistics that make data collection difficult. Here, we ... -
A Possible Feedback Mechanism Involving the Arctic Freshwater, the Arctic Sea Ice, and the North Atlantic Drift
(Advances in Atmospheric Sciences;21( 5), Journal article, 2004-03-15)Model studies point to enhanced warming and to increased freshwater fluxes to high northern latitudes in response to global warming. In order to address possible feedbacks in the ice-ocean system in response to such changes, ... -
Seasonality of the Physical and Biogeochemical Hydrography in the Inflow to the Arctic Ocean Through Fram Strait
(Peer reviewed; Journal article, 2018-06-29)Eastern Fram Strait and the shelf slope region north of Svalbard is dominated by the advection of warm, salty and nutrient-rich Atlantic Water (AW). This oceanic heat contributes to keeping the area relatively free of ice. ... -
Snowmelt contribution to Arctic first-year ice ridge mass balance and rapid consolidation during summer melt
(Journal article; Peer reviewed, 2023)Sea ice ridges are one of the most under-sampled and poorly understood components of the Arctic sea ice system. Yet, ridges play a crucial role in the sea ice mass balance and have been identified as ecological hotspots ... -
Species composition, distribution and ecology of the demersal fish community along the Norwegian coast north of Stad under varying environmental conditions
(Master thesis, 2019-06-14)In the last decades, temperatures of the Atlantic current that enters the Norwegian Coastal Current (NCC) has been above the yearly average, with 2007 as the warmest registration on record (Skagseth 2012). The climatic ... -
Temporal evolution of under-ice meltwater layers and false bottoms and their impact on summer Arctic sea ice mass balance
(Journal article; Peer reviewed, 2023)Low-salinity meltwater from Arctic sea ice and its snow cover accumulates and creates under-ice meltwater layers below sea ice. These meltwater layers can result in the formation of new ice layers, or false bottoms, at the ... -
Thin and transient meltwater layers and false bottoms in the Arctic sea ice pack-Recent insights on these historically overlooked features
(Journal article; Peer reviewed, 2023)The rapid melt of snow and sea ice during the Arctic summer provides a significant source of low-salinity meltwater to the surface ocean on the local scale. The accumulation of this meltwater on, under, and around sea ice ... -
Vertical mixing in the Arctic Ocean inferred from eXpendable Current Profilers
(Master thesis, 2011-05-31)Recent and historical data sets from different regions of the Arctic Ocean are analysed using velocity profiles from 127 eXpendable Current Profiler (XCP) deployments from the time period 1993 to 2010. The data sets are ...
