Characterization of the coastal marine atmospheric boundary layer (MABL) for wind energy applications
(Master thesis, 2013-06-03)The main problem for the characterization of marine atmospheric boundary layer is the lack of available offshore measurements in relevant altitude range up to 200 m. Remote sensing meteorological instruments such as LIDARs ... -
Characterization of the SUMO Turbulence Measurement System for Wind Turbine Wake Assessment
(Peer reviewed; Journal article, 2014)The remotely piloted aircraft system (RPAS) SUMO (Small Unmanned Meteorological Observer) has been equipped with a miniaturized 5-hole probe sensor system for measurement of the 3-dimensional flow vector with a temporal ... -
Characterization of turbulence in wind turbine wakes under different stability conditions from static Doppler LiDAR measurements
(Peer reviewed; Journal article, 2017-03-05)Wake characteristics are of great importance for wind park performance and turbine loads. While wind tunnel experiments provided a solid base for the basic understanding of the structure and dynamics of wind turbine wakes, ... -
Characterization of Wind-Sea- and Swell-Induced Wave Energy along the Norwegian Coast
(Journal article; Peer reviewed, 2020)The necessity to reduce CO2 emissions in combination with the rising energy demand worldwide makes the extensive use of renewable energy sources increasingly important. To that end, countries with long coastlines, such as ... -
Characterizing Atlantic interhemispheric teleconnection established by South American monsoon in austral summer
(Journal article; Peer reviewed, 2023)This study aims to characterize the interhemispheric teleconnection pattern, which is established by the South America (SA) summer monsoon over the Atlantic Ocean during January and February, and referred it as the Atlantic ... -
Characterizing the convective boundary layer with wind-profiling and scanning Doppler lidar
(Doctoral thesis, 2024-04-22)Konveksjon har stor innvirkning på strukturen og utviklingen av det atmosfæriske grenselaget. Det er imidlertid utfordrende å måle de karakteristiske lengde- og tidsskalaene ved hjelp av konvensjonelle meteorologiske ... -
ChemicalDrift 1.0: an open-source Lagrangian chemical-fate and transport model for organic aquatic pollutants
(Journal article; Peer reviewed, 2023)A new model for transport and fate of chemicals in the aquatic environment is presented. The tool, named ChemicalDrift, is integrated into the open-source Lagrangian framework OpenDrift and is hereby presented for organic ... -
Circulation along the northern slope of the Greenland-Scotland Ridge
(Doctoral thesis, 2020-12-11)The Greenland-Scotland Ridge separates the subpolar North Atlantic from the Nordic Seas and constrains the flow of the upper and lower branches of the northern extremity of the Atlantic Meridional Overturning Circulation ... -
Circulation and exchange of water masses on the Faroe Shelf and the impact on the Shelf ecosystem
(Doctoral thesis, 2009-02-11)The findings in this work can be listed as follows: FSW: Based on CTD data, the FSW is found to be relatively vertically homogeneous through-out the year inside the 100 m depth contour. Temperature measurements at coastal ... -
Circulation and Hydrography in the Northwestern Barents Sea: Insights From Recent Observations and Historical Data (1950–2022)
(Journal article; Peer reviewed, 2024)The Barents Sea is one of the main pathways for warm and saline Atlantic Water (AW) entering the Arctic Ocean. It is an important region where water mass transformation and dense-water production contribute to the Atlantic ... -
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 ... -
Circulation and transformation of Atlantic and Arctic water masses in climate models
(Doctoral thesis, 2011-12-09)Ocean heat transport and associated heat loss to the atmosphere contributes significantly to the anomalously mild climate of northwestern Europe and its variability. In this thesis, the circulation and transformation of ... -
Circulation and water masses beneath the northern Ronne Ice Shelf, Antarctica
(Journal article; Peer reviewed, 2004-12-14)We present oceanographic data from beneath the northern Ronne Ice Shelf. The data were collected during the austral summer of 2002–2003 from four sites located near the ice front in the Ronne Depression. They consist of ... -
Circulation features in the northern North Atlantic Ocean inferred from simulated radioactive tracers
(Doctoral thesis, 2008-03-12) -
The circulation of the Norwegian Sea- An investigation from space and ocean
(Doctoral thesis, 2014-01-10)The Norwegian Sea circulation plays a key role in maintaining the mild climate of the northwestern Europe via the transport of warm Atlantic Water pole-ward. The first paper addresses the advective currents connecting the ... -
Circulation responses to surface heating and implications for polar amplification
(Journal article; Peer reviewed, 2024)A seminal study by Hoskins and Karoly (1981) explored the atmospheric circulation response to tropospheric heating perturbations at low latitudes and midlatitudes. Here we revisit and extend their study by investigating ... -
Climate based multi-year predictions of the Barents Sea cod stock.
(Peer reviewed; Journal article, 2018-10-24)Predicting fish stock variations on interannual to decadal time scales is one of the major issues in fisheries science and management. Although the field of marine ecological predictions is still in its infancy, it is ... -
