      Martiuk, Daria (Master thesis; Mastergradsoppgave, 2017-06-21)
      Three-dimensional (3-D) seismic interpretations of data from the Samson Dome show direct connection between the local geological evolution of the area and the regional tectonic and stratigraphic development of the western Barents Sea. Rifting events, halokinetic movements, uplift and glacial processes influenced the area of the Samson Dome. The Samson Dome structure, located in the south-western ...

Skolen er et pilotprosjekt i tråd med Rogaland fylkeskommune sin miljøpolitikk og er bygget med fokus på bærekraftige prinsipper, lavt energiforbruk og bruk av energikilder med begrenset CO2 utslipp. Skolens varme ...
    • Assessment of the Remaining Carbon Budget: A Comparison of a Simple Response Model and the MAGICC Model. 

      Martinsen, Andreas Rostrup (Master thesis; Mastergradsoppgave, 2020-06-15)
      We are changing the global climate by altering the Earths energy balance through the emission of greenhouse gasses. The international community aims to prevent dangerous warming with mitigative efforts. A remaining carbon budget (RCB) can roughly quantify an allowable amount of emissions for keeping the temperature below a set target. We have built a simple climate model using impulse response ...
    • Assessment of the Remaining Carbon Budget: Incorporating Arctic Amplification in a Simple Response Model 

      Johansen, Andreas (Master thesis; Mastergradsoppgave, 2020-06-15)
      Remaining carbon budgets (RCBs) quantify the total amount of CO2 that can still be emitted into the atmosphere while keeping the global mean surface temperature below a specific target. However, there is significant uncertainty in RCBs estimates. This thesis develops a Simple Response Model (SRM) to explore the uncertainties in RCBs. We use temperature response functions estimated from multi-box ...
    • Assessment of the Remaining Carbon Budget: Incorporation of Nonlinear Feedbacks in a Simple Response Model 

      Mentzoni, Endre Falck (Master thesis; Mastergradsoppgave, 2020-06-15)
      Anthropogenic emission of greenhouse gases is causing an unbalance in the Earth’s climate system, leading to global climate change. The implications of these changes are dramatic, with a need for a global-scale assessment. The remaining carbon budget (RCB) is a measure of the amount of greenhouse gasses (GHGs) that can be emitted if we are to reach a specific temperature target. Traditionally, carbon ...
    • Automatic validation of Sentinel-1 borne snow avalanche detections 

      Pedersen, Jarle Langseth (Master thesis; Mastergradsoppgave, 2020-05-30)
      Snow avalanches threaten human lives, settlements and roads in snow covered mountainous areas. For avalanche forecasting, knowledge of the spatio-temporal occurrence of avalanche activity is critical. Automatic avalanche detection algorithms have been developed to enable consistent avalanche activity monitoring for large regions. The Satskred avalanche detection algorithm developed by NORCE applies ...

The systems are located in western and southeastern Norway and near horizontal, tilted and vertical modules are looked at. Results show pretty ...
    • Case study of a large-scale solar and wind power hybrid system at Fakken Wind Farm, Troms 

      Tiller, Charlotte (Master thesis; Mastergradsoppgave, 2017-06-01)
      The objective of this thesis is to investigate the feasibility of a large scale hybrid system at Fakken, Troms. There is already an existing 54 MW wind farm at site. The wind farm has considerably higher power production during winter compared to summer, and the electricity grid is therefore not fully exploited during summer. Adding a solar panel utility to the site could be a solution to this issue. ...

      Ingebrigtsen, Karoline (Master thesis; Mastergradsoppgave, 2017-06-06)
      The power company Troms Kraft is interested in the feasibility of a large-scale hybrid system in Skibotndalen in Troms. There are two existing hydro power stations in the area, and this thesis concerns the addition of an electric solar power plant of 20 MW and a wind power plant of 21 MW to these stations. As measured solar radiation is not available for one whole year at the location, solarradiation ...

      Sediment core HH16-549GC from Vestnesa Ridge in the Fram Strait, western Svalbard, has been investigated in order to reconstruct paleoceanographic and paleoclimatic conditions from 31,000 to 7500 cal years BP. Vestnesa Ridge is located in an area with extensive seepage of methane from the ocean floor. The core is retrieved from within a pockmark to reconstruct possible changes in seepage of methane ...

This study looked the how ASAR and model wind ...
    • Combining ENVISAT ASAR and MODIS data to enable improved snow cover maps 

      Mjøen, Håvard Uv (Master thesis; Mastergradsoppgave, 2008-06)
      Information about snow covered area is important for several purposes, and this information can be found by detecting reflection of optical waves using optical sensors or by using active radars such as SAR. This thesis is explaining how information from the measurements are used to make snow maps. Optival sensors cannot detect snow when the area is covered by clouds, and this is a problem in the ...

    • Constraining Transient Climate Response Using the Historical Temperature Record 

      Tranås, Olaf Lehn (Master thesis; Mastergradsoppgave, 2018-06-01)
      Anthropogenic greenhouse gas emissions alter the planet's energy balance and cause heating of the surface and oceans. Estimates of the implications of continued emissions are necessary to assess the severity of the situation. The transient climate response (TCR) is a measure of the climate's response to a continued increase in CO2 concentration, and indicates how much the temperature will increase ...
    • The Cretaceous development of the Nordkapp Basin based on seismic interpretation 

      Matveev, Aleksei (Master thesis; Mastergradsoppgave, 2018-05-31)
      This thesis is focused on studying the development of the Nordkapp Basin during the Cretaceous Period. The basin is fault-controlled and is strongly influenced by salt tectonics. The basin is divided into two parts, which differs both in the average width and direction of their elongation. Moreover, the salt structures in the northeast and southwest parts of the basin also follow the trends in width ...
    • Decentralized wind power as part of the relief for an overstrained grid. A case study on Northern Senja, Norway 

      Bednorz, Paul (Master thesis; Mastergradsoppgave, 2019-08-12)
      The most significant factor in wind turbine siting is the wind conditions. Those often determine the economic and ecologic success of a project. Especially in topographically complex areas micro siting can be difficult and costly. Small and medium scale projects often lack the knowledge and resources for an extended in situ assessment. A combination of modelled wind data and the use of a geographic ...

    • A detailed investigation of a geological CO2-storage reservoir 

      Hatland, Anna Maria (Master thesis; Mastergradsoppgave, 2015-05-31)
      Increased CO2-concentrations within the atmosphere of the Earth have encouraged development of “carbon capture and storage” (CCS). It is important to avoid global warming, and CO2 may be stored within geological formations in the subsurface. This thesis focuses on the possibilities of storing CO2 in a reservoir of Middle Triassic-Middle Jurassic age in The Nordkapp Basin, The Southern Barents ...
