100-year waves in the Mozambique Channel
(Master thesis, 2010-06-01)Six-hourly significant wave height (SWH) data covering the period September 1957 to August 2002 is obtained from the ERA-40 reanalysis. This data, generated by ECMWF's own configured global WAM model, stems from the first ... -
Addressing the observational gap over heterogeneous land surfaces in the lower atmospheric boundary layer by multi-copter temperature and humidity profile measurements
(Master thesis, 2024-06-03)The effects of surface heterogeneity on the atmospheric boundary layer are still poorly understood and thus not appropriately parameterized in numerical weather prediction models. The complexity of types, shapes, and scales ... -
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 ... -
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 ... -
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 ... -
Bottom melting of Arctic Sea Ice in the Nansen Basin due to Atlantic Water influence
(Master thesis, 2016-05-24)The hydrographic situation for a region north of Svalbard is investigated using observations from the Norwegian Young Sea Ice Cruise (N-ICE2015). Observations from January to June 2015 are compared to historical observations ... -
Circulation and Ocean Driven Glacial Melting in a Greenland Fjord
(Master thesis, 2017-11-20)The Nioghalvfjerdsbræ (79NG) is a floating ice tongue on Northeast Greenland draining a large part of the Greenland Ice Sheet. New hydrographic observations show that Atlantic Water (AW, T > 0 °C, S > 34.3 psu) recirculates ... -
Climate forcing of summer carbon drawdown in the subpolar North Atlantic
(Master thesis, 2015-08-28)This thesis present a 9-year long time series of surface seawater fCO2 data obtained aboard the MV Nuka Arctica. The Nuka Arctica provide full seasonal fCO2 measurements which give a good picture of the fCO2 variability ... -
Climatology of polar lows impacting Norway
(Master thesis, 2016-06-01)Polar lows (PLs), mesoscale cyclones in high latitudes, impacting Norway are studied in this thesis. A climatology of PLs in the Nordic seas for the period 1979-2015 is made, by applying a cyclone detection and tracking ... -
Constraining the exchange through the strait of Bab el Mandab
(Master thesis, 2012-10-01)The strait of Bab el Mandab connects the Red Sea with the Indian ocean via the Gulf of Aden. The mean circulation at the strait is a three-layered exchange. The circulation in the Red Sea is understood to be driven by the ... -
Deep weakly-stratified layers in the Greenland Sea
(Master thesis, 2021-12-06)Deep weakly-stratified layers in the Greenland Sea constitute a mode of convection poorly understood. The Greenland Sea is where the densest portion of the overflow waters on either side of Iceland are formed through ... -
Dense water formation in the Greenland Sea between 1999 and 2009
(Master thesis, 2019-08-22)A 10-year continuous hydrographic data record from moored profilers located in the central Greenland Sea between 1999 and 2009 were used to examine the mixed-layer depth evolution through winter as well as interannual ... -
The development and evaluation of an idealized ocean model for the Bergen Dynamic Model
(Master thesis, 2013-11-20)Three idealized ocean model versions are developed for the Bergen Dynamic Model (Bedymo). All three model versions fall into the category of slab ocean models. One version is more or less a standard slab ocean model, while ... -
