Ice and brine production in Hornsund
(Master thesis, 2015-06-02)The Hornsund fjord system has been studied using observations of the atmosphere, ocean and sea ice, and two different types of models. The study documents significant year to year variability in sea ice formation and brine ... -
Idealized Modeling of the North Icelandic Jet
(Master thesis, 2023-06-01)The North Icelandic Jet (NIJ) is a crucial component of the lower limb of the Atlantic Meridional Overturning Circulation, supplying one-third to one-half of the overflow water transport through Denmark Strait, including ... -
Individual based modeling of North Atlantic common minke whale (Balaenoptera acutorostrata) migratory and foraging behaviour in the Nordic Seas
(Master thesis, 2014-09-01)The North Atlantic common minke whale (Balaenoptera Acutorostrata) is an abundant, top-level marine predator in the Nordic Seas and Barents Sea ecosystems whose large-scale migratory and foraging behaviors are widely ... -
Interannual variations of freshwater content in Hornsund
(Master thesis, 2015-05-04)Salinity measurements have been used to calculate the freshwater content in Hornsund for the years 2001 to 2014. In 2011 there was significantly higher freshwater content in the fjord, compared to the other years, with a ... -
Investigations on the External Forcings acting on the Convective Boundary Layer during the BLLAST Campaign by the CLASS Model
(Master thesis, 2017-06-20)Using both observed and modelled datasets from the 2011 Boundary Layer Late Afternoon and Sunset Turbulence (BLLAST) campaign, the influence of large-scale forcings and surface heterogeneity is investigated for ten out of ... -
Karbondynamikk i Grønlandshavet observert av en Argobøye og en 1-D Blandingsmodell

Korrigering av modellestimert nedbør ved hjelp av historisk data.
(Master thesis, 2010-06-01)I denne oppgåva er det sett på moglegheit for betring av modellestimert nedbør ved å korrigere modellerte nedbørsestimat ved hjelp av fleire ulike korreksjonsfaktorar som tar omsyn til ulike vêrtypar og nedbørsintensiteten. ... -
Langmuir Turbulence in the HYCOM Ocean Model
(Master thesis, 2017)The impact of parameterising the turbulent mixing induced by surface wave-driven Langmuir turbulence is investigated for a basin-scale configuration of the hybrid-coordinate ocean circulation model HYCOM. Two-year, non-data ... -
Late winter response to atmospheric and tidal forcing in the Førdefjord, inferred from mooring observations
(Master thesis, 2018-06-20)The Førdefjord is a narrow fjord on the western coast of Norway. A shallow sill is situated at the Ålasund, in the centre part of the fjord. A deep basin, 3 km north of the sill, has been approved as a deposit site for ... -
The linear stationary wave response to Arctic amplification related heating
(Master thesis, 2015-06-01)There has been a raft of manuscripts which claim to show that Arctic amplification (AA) is responsible for changes in the large-scale wintertime midlatitude atmospheric circulation. Responses to these studies have shown ... -
Local flow conditions in the Bergen valley based on observations and numerical simulations
(Master thesis, 2012-10-16)The complex topography and variability in surface roughness in the Bergen valley aff-ects the flow conditions in a multitude of ways. The steep mountains give shelter during strong synoptic flow, but the orography of Bergen ... -
Lofoten eddies observed by Seagliders
(Master thesis, 2018-11-22)When the Norwegian Atlantic Current passes the Lofoten Basin, it loses a large amount of mass and heat to mesoscale eddies as a result of instabilities of the mean current along the Norwegian Slope. The eddies subsequently ... -
Long-term changes in the Nordic Seas' hydrographic structure and overflow waters
(Master thesis, 2020-06-30)A collection of historical hydrographic data was used to examine the hydrographic properties of the water masses in the Nordic Seas from 1950 to 2018, with particular focus on the dense overflows from the Nordic Seas. ... -
Low Level Jet Streams at the Sea Ice Edge - Numerical Simulations using WRF
(Master thesis, 2013-06-03)The goal of the presented thesis is to investigate the formation of low level jets at the sea ice edge. Differential heating creates very sharp fronts at the ice edge. A transversal circulation, initiated by altered pressure ... -
Mapping the fugacity of CO2 in the Nordic Seas and the northern North Atlantic Ocean
(Master thesis, 2013-12-20)Self organizing maps (SOMs) have been used to estimate seawater fugacity of CO2 (fCO2) distribution in the Nordic Seas and the northern North Atlantic Ocean for 2005-2007. Four maps were produced for each region using ... -
MARINE PLASTIC DRIFT FROM THE MEKONG RIVER TO SOUTHEAST ASIA
(Master thesis, 2022-11-21)Plastic waste has been identified as a major worldwide environmental issue (Sun et al., 2021; Zhang et al., 2020). Jambeck et al. (2015) estimated that between 4.8 and 12.7 million tons of plastic waste enters the ocean ... -
Målt og Modellert Globalstråling ved Ekofisk og i Nordområdene
(Master thesis, 2011-06-01)I dette arbeidet er globalstrålingsdata fra Ekofisk, Arktis og fastlandsstasjoner i Norge og Sverige studert. Stasjonene ligger mellom 56°N og 75°N, og all data er hentet fra perioden 2005 til og med 2010. Målinger i Arktis ... -
Measured, modelled and satellite derived solar radiation in Scandinavia
(Master thesis, 2011-06-01)This article presents a comparison of global radiation data at different sites at the Scandinavian Peninsula. It makes use of ground truth, modelled and satellite derived surface global radiation data. First, a quality ...
