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 ... -
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 ... -
Microstructure measurements using a glider in the Faroe Bank Channel Overflow
(Master thesis, 2013-05-30)The application of turbulence instrumentation on underwater gliders is addressed, and two methods for glider-inferred dissipation rates of turbulent kinetic energy are evaluated against a ship-based vertical microstructure ... -
Numerical modelling of the sub-surface melting of marine-terminating glaciers in Arctic fjords
(Master thesis, 2015-06-01)Submarine melting of glaciers terminating in fjords is likely to be of high importance regarding the total ice loss from ice sheets and ice caps and the resulting addition of freshwater to the ocean. Submarine melting ... -
Ocean acidication in the Arabian Sea and the Red Sea - factors controlling pH
(Master thesis, 2010-06-01)The CO2 increase in the ocean due to uptake of anthropogenic CO2 and the companying lowering of ocean pH is of major concern. In this study we investigated the variability of CO2 system parameters, focusing particularly ... -
On the Influence of Latent and Sensible Heating for Maintaining Baroclinicity in the Gulf Stream Region
(Master thesis, 2016-06-01)For the North Atlantic storm track to collocate with the ocean front, there has to be efficient restoring mechanisms for baroclinicity. The total diabatic heating is agreed to play the most dominant role, but whether the ... -
Origin of moisture at Arctic sites
(Master thesis, 2016-06-01)The hydrological cycle is an important component in the understanding of the climate system, and a good understanding of the moisture transport in the atmosphere is important in a changing climate. The climate change may ... -
Peak-summer energy and carbon fluxes on a thawing permafrost site
(Master thesis, 2018-12-13)We present measurements of surface fluxes taken between 7 July and 6 August 2017, on a palsa mire near the Iškoras mountain in Finnmark, northern Norway. Palsa mires are a particular landform found at the edge of the ... -
Physical-Biogeochemical Couplings in the Land-Ocean Transition Zone
(Master thesis, 2014-06-03)A significant fraction of global primary production takes place on continental shelves. Due to their interactions with the open oceans, they are highly relevant for the cycling of nutrients, oxygen, and carbon, not only ... -
Pre-bloom dynamics of the Subpolar North Atlantic microbial food web
(Master thesis, 2013-02-18)The aim of this study was to investigate the microbial planktonic food web in the pre- bloom period of the Subpolar North Atlantic Ocean. Through repeated visits to the Icelandic Basin, Norwegian Basin, and on the Shetland ... -
Properties of the Yellow Sea Meteotsunamis in Spring
(Master thesis, 2015-06-01)This paper documents the properties of the Yellow Sea meteotsunamis in spring based on a total num- ber of 49 meteotsunami events in spring (Mar-May) between 2002 and 2013 documented by the Korea Meteorological Administration ... -
A quantitative description of the West Spitsbergen Current by combining hydrography, altimetry and in-situ current meters
(Master thesis, 2014-06-02)In a warming Arctic Ocean (AO) it is important to study its main source of oceanic heat and salt. Here, seasonal climatological sections of the West Spitsbergen Current (WSC) across 78.83°N have been constructed using ... -
Reconstruction of Glacier Mass Balance and Sensitivity Tests to Climate Change: A case study of Ålfotbreen and Nigardsbreen
(Master thesis, 2011-11-30)A physically-based one dimensional CROCUS snow model was applied to simulate the surface mass balances of Ålfotbreen (1964-2009) and Nigardsbreen (1962-2009) in southern Norway. The required hourly meteorological input ... -
Sea level variation in the Red Sea based on SODA data
(Master thesis, 2012-10-01)In this study we investigate the sea level variation in the Red Sea focusing on wind stress setup. 50-years dataset from 1957 to 2007 of sea level and wind stress from Simple Ocean Data Assimilation (SODA) data version ... -
Seasonal and Interannual Variations of Surface Nutrients and Hydrography in the Norwegian Sea
(Master thesis, 2012-10-01)Seasonal and interannual variations of surface nutrients and hydrography data obtained in period (1997-2010) by the Institute of Marine Research over three transects: Fugløya-Bjørnøya, Gimsøy and Svinøy located in the ... -
Seasonality of Surface Chlorophyll in the Red Sea
(Master thesis, 2012-10-01)Although the understanding of the oceanography of the Red Sea has been developed over the last few decades, but we still have a little knowledge about the influences of the physical factors on the phytoplankton activity. ... -
Skier stability index - An additional tool for snow avalanche forecasting in Norway?
