Unusual subduction zones: Case studies in Colombia and Iran
(Doctoral thesis, 2007-02-16)Subduction zones, usually, are plate boundaries with the highest level of seismic activity. However, the distribution of seismicity in these plate margins is not uniform in the frequency and magnitude. Some margins produce ... -
An update to the Surface Ocean CO2 Atlas (SOCAT version 2)
(Peer reviewed; Journal article, 2014-03-07)The Surface Ocean CO2 Atlas (SOCAT), an activity of the international marine carbon research community, provides access to synthesis and gridded fCO2 (fugacity of carbon dioxide) products for the surface oceans. Version 2 ... -
An updated version of the global interior ocean biogeochemical data product, GLODAPv2.2020
(Journal article; Peer reviewed, 2020)The Global Ocean Data Analysis Project (GLODAP) is a synthesis effort providing regular compilations of surface-to-bottom ocean biogeochemical data, with an emphasis on seawater inorganic carbon chemistry and related ... -
An updated version of the global interior ocean biogeochemical data product, GLODAPv2.2021
(Journal article; Peer reviewed, 2021)The Global Ocean Data Analysis Project (GLODAP) is a synthesis effort providing regular compilations of surface-to-bottom ocean biogeochemical bottle data, with an emphasis on seawater inorganic carbon chemistry and related ... -
Upper Ocean Response to Large Wind Farm Effect in the Presence of Surface Gravity Waves
(Peer reviewed; Journal article, 2012)The upper ocean response in the presence of a wind farm is studied numerically, taking into account the effect of surface gravity waves. The farm geometry is a simplified rigid rectangle with characteristic size of L aligned ... -
Upper tropospheric cloud-radiation interaction induced by monsoon surge over the South China Sea
(Journal article; Peer reviewed, 2023)We have investigated cloud formation over the South China Sea in the upper troposphere and its impacts on the radiation budget of the troposphere and ocean surface under monsoon surges using satellite and reanalysis products ... -
Upper-ocean hydrography in the Eurasian Basin and its implication on sound speed
(Master thesis, 2022-08-15)The Polar Surface Water (PSW) and the Atlantic Water (AW) characteristics and their vertical extent are investigated using data from three moorings deployed in the Nansen Basin, north of Svalbard, under the Coordinated ... -
Upper-ocean turbulence structure and ocean-ice drag coefficient estimates using an ascending microstructure profiler during the MOSAiC drift
(Journal article; Peer reviewed, 2022)Sea ice mediates the transfer of momentum, heat, and gas between the atmosphere and ocean. However, the under-ice boundary layer is not sufficiently constrained by observations. During the Multidisciplinary drifting ... -
Upstream sources of the Denmark Strait Overflow: Observations from a high-resolution mooring array
(Peer reviewed; Journal article, 2016)We present the first results from a densely instrumented mooring array upstream of the Denmark Strait sill, extending from the Iceland shelfbreak to the Greenland shelf. The array was deployed from September 2011 to July ... -
Using machine learning algorithms to enhance numerical weather prediction
(Master thesis, 2022-11-21)In this master thesis machine learning algorithms have been used in an effort to enhance numerical weather prediction. The learning algorithms used are random forest to provide a no precipitation/precipitation classification, ... -
Utilizing Solar Vapour Energy by Use of Nanofluids in a Direct Absorption Solar Collector
(Master thesis, 2018-01)Traditional solar thermal collectors and photovoltaic (PV) systems suffer from low energy conversion efficiencies. This is mainly due to high thermal losses from overheated absorber plates or solar cells. For steam generation ... -

Validating Finescale Parameterizations for the Eastern Arctic Ocean Internal Wave Field
(Journal article; Peer reviewed, 2023)In the Arctic Ocean, vertical transport of heat by turbulent mixing is ultimately coupled to the sea-ice cover, with immediate and far-reaching impacts on the climate and ecosystem. Unfortunately, direct observations of ... -
Validation of boundary layer parameterization schemes in the Weather Research and Forecasting Model (WRF) under the aspect of offshore wind energy applications - Part II: Boundary layer height and atmospheric stability
(Peer reviewed; Journal article, 2015-07)Five different planetary boundary layer (PBL) schemes in the Weather Research and Forecasting (WRF) model have been tested with respect to their capability to model boundary layer parameters relevant for offshore wind ... -
Validation of precipitation forecasts from the AROME numerical weather prediction model in Norway
(Master thesis, 2022-11-21)High-quality precipitation forecasts are key to ensure the public and economic safety during severe precipitation events, and the process of validating these forecasts is a continuous effort. But with Norway's varied climate ... -
Variability along the Atlantic water pathway in the forced Norwegian Earth System Model
(Peer reviewed; Journal article, 2018-03-27)The growing attention on mechanisms that can provide predictability on interannual-to-decadal time scales, makes it necessary to identify how well climate models represent such mechanisms. In this study we use a high (0.25° ... -
Variability and decadal trends in the Isfjorden (Svalbard) ocean climate and circulation – An indicator for climate change in the European Arctic
(Journal article; Peer reviewed, 2020)Isfjorden, a broad Arctic fjord in western Spitsbergen, has shown significant changes in hydrography and inflow of Atlantic Water (AW) the last decades that only recently have been observed in the Arctic Ocean north of ... -
Variability and mixing of the Filchner overflow plume on the continental slope,Weddell Sea
