Analyses of the potential role of hydrogen for Norway in the transition to a zero-emission society
(Master thesis, 2017-06-23)The objective of this thesis is to analyze the potential role of hydrogen for Norway in the transition to a zero-emission society. The main sector of focus is the transport sector. Here, socioeconomic analyses are carried ... -
Analysis of 3 years of precipitation measurements from the Micro Rain Radar located at the Geophysical Institute
(Master thesis, 2013-11-20)An analysis of three years of vertically pointing Micro Rain Radar (MRR) data from the measurement platform at the Geophysical Institute has been performed. The measurement period started at 13.04.2010 and ended at 12.04.2013. ... -
Annual and Seasonal Mean Net Evaporation Rates of the Red Sea Water during Jan 1958 - Dec 2007
(Master thesis, 2012-10-01)Data set including sea level, temperature, salinity, and current from Simple Ocean Data Assimilation (SODA) is used in this study to estimate the mean net annually and seasonally evaporation rates. Then wind data is used ... -
Anthropogenic Carbon in the Nordic seas and Arctic Ocean, 1994 to 2007
(Master thesis, 2019-06-28)The increase of anthropogenic CO2 between 1994 and 2007 is quantified in the Nordic seas and Arctic Ocean with the extended multiple linear regression method (eMLR(C*)). To be able to map the increase in anthropogenic CO2 ... -
Application of the unmanned Offshore Sensing SailBuoy for validation of ocean model simulations and remote sensing data in the North Atlantic
(Master thesis, 2015-12-01)The Offshore Sensing SailBuoy, is a remotely controlled, wind driven unmanned ocean vehicle. It sampled near surface properties during a mission in the North Atlantic in June - August 2014. Three parameters were recorded, ... -
The Arctic Sea Ice - Melting During Summer or not Freezing in Winter?
(Master thesis, 2016-06-01)The Arctic sea ice cover has retreated rapidly during the last three decades, concurrent with recent global temperature increase both in the atmosphere and in the ocean. The sea ice cover has experienced a retreat in extent ... -
Arctic Wintertime Sea Ice Breakup Events - Detection and Evolution
(Master thesis, 2024-06-03)Openings in the Arctic sea ice give rise to strong localized heat fluxes from the ocean to the atmosphere, causing ocean mixing and potentially leading to new sea ice growth. Despite the increased attention on sea ice ... -
Artificial gas supersaturated water from small hydropower plants: methods to detect air entrainment at intakes
(Master thesis, 2022-06-01)Hydropower plants with submerged intake and Francis turbine can release artificial Total Dissolved Gas (TDG) supersaturated water from the plants outlet, if air is drawn into the pressure pipe at intake and dissolved in ... -
Atlantic Multidecadal Variability (AMV) in the Norwegian Earth System model
(Master thesis, 2020-06-26)The causes of low-frequency sea surface temperature (SST) variations in the Atlantic, known as Atlantic Multidecadal Variability (AMV), are debated. AMV has climatic impacts on for instance hurricane activity and Sahel ... -
Atmospheric response to removal of Southern Hemisphere sea ice - a model study
(Master thesis, 2010-06-01)The atmospheric response to the removal of Southern Hemisphere sea ice is studied using the ICTP AGCM (SPEEDY) model with an uncoupled ocean. The results show large increases in surface heat flux from the ocean to the ... -
Atmospheric response to zonally averaged sea surface temperatures in the North Atlantic - a model study
(Master thesis, 2008-05-29)A less dynamically active ocean will most likely lead to a more zonal sea surface temperature (SST) distribution. In order to identify if, and how such an effect affects the atmospheric variability, idealized experiments ... -
