Sea-state contributions to sea-level variability in the European Seas
(Journal article; Peer reviewed, 2020)The contribution of sea-state-induced processes to sea-level variability is investigated through ocean-wave coupled simulations. These experiments are performed with a high-resolution configuration of the Geestacht COAstal ... -
Seasonal and Interannual Variations of Surface Nutrients and Hydrography in the Norwegian Sea
(Master thesis, 2012-10-01)Seasonal and interannual variations of surface nutrients and hydrography data obtained in period (1997-2010) by the Institute of Marine Research over three transects: Fugløya-Bjørnøya, Gimsøy and Svinøy located in the ... -
The Seasonal and Regional Transition to an Ice-Free Arctic
(Journal article; Peer reviewed, 2021)The Arctic sea ice cover is currently retreating and will continue its retreat in a warming world. However, the loss of sea ice is neither regionally nor seasonally uniform. Here, we present the first regional and seasonal ... -
Seasonal dynamics of the marine CO2 system in Adventfjorden, a West Spitsbergen fjord
(Peer reviewed; Journal article, 2019-06-11)Time series of the marine CO2 system and related parameters at the IsA Station, by Adventfjorden, Svalbard, were investigated between March 2015 and November 2017. The physical and biogeochemical processes that govern ... -
Seasonal Outflow of Ice Shelf Water Across the Front of the Filchner Ice Shelf, Weddell Sea, Antarctica
(Peer reviewed; Journal article, 2018-04)The ice shelf water (ISW) found in the Filchner Trough, located in the southern Weddell Sea, Antarctica, is climatically important; it descends into the deep Weddell Sea contributing to bottom water formation, and it blocks ... -
Seasonal predictability of Kiremt rainfall in coupled general circulation models
(Journal article; Peer reviewed, 2017)The Ethiopian economy and population is strongly dependent on rainfall. Operational seasonal predictions for the main rainy season (Kiremt, June–September) are based on statistical approaches with Pacific sea surface ... -
Seasonal predictions initialised by assimilating sea surface temperature observations with the EnKF
(Peer reviewed; Journal article, 2019-07-23)This study demonstrates that assimilating SST with an advanced data assimilation method yields prediction skill level with the best state-of-the-art systems. We employ the Norwegian Climate Prediction Model (NorCPM)—a ... -
Seasonal resonance of diurnal coastal trapped waves in the southern Weddell Sea, Antarctica
(Peer reviewed; Journal article, 2017-01-30)The summer enhancement of diurnal tidal currents at the shelf break in the southern Weddell Sea is studied using velocity measurements from 29 moorings during the period 1968 to 2014. Kinetic energy associated with diurnal ... -
Seasonal to Decadal Temperature Variations in the Faroe-Shetland Inflow Waters
(AGU Geophysical Monograph Series;158, Chapter, 2005)A 53 years hind-cast simulation with a regional version of the Nansen Center version of the Miami Isopycnic Coordinate Ocean Model (MICOM) has been conducted to explore the nature of the observed seasonal to inter-annual ... -
Seasonal variation in marine C:N:P stoichiometry: can the composition of seston explain stable Redfield ratios?
(Peer reviewed; Journal article, 2011)Seston is suspended particulate organic matter, comprising a mixture of autotrophic, heterotrophic and detrital material. Despite variable proportions of these components, marine seston often exhibits relatively small ... -
Seasonal-to-decadal predictions with the ensemble kalman filter and the Norwegian earth System Model: A twin experiment
(Peer reviewed; Journal article, 2014-03-10)Here, we firstly demonstrate the potential of an advanced flow dependent data assimilation method for performing seasonal-to-decadal prediction and secondly, reassess the use of sea surface temperature (SST) for initialisation ... -
Seasonality of coastal upwelling trends in the Mauritania-Senegalese region under RCP8.5 climate change scenario
(Journal article; Peer reviewed, 2023)The Mauritania-Senegalese upwelling region (MSUR), the southernmost region of the Canary current upwelling system, is well-known for its coastal productivity and the key role it plays in enriching the oligotrophic open ... -
Seasonality of Surface Chlorophyll in the Red Sea
(Master thesis, 2012-10-01)Although the understanding of the oceanography of the Red Sea has been developed over the last few decades, but we still have a little knowledge about the influences of the physical factors on the phytoplankton activity. ... -
Self-nested large-eddy simulations in PALM model system v21.10 for offshore wind prediction under different atmospheric stability conditions
(Journal article; Peer reviewed, 2023)Large-eddy simulation (LES) resolves large-scale turbulence directly and parametrizes small-scale turbulence. Resolving micro-scale turbulence, e.g., in wind turbine wakes, requires both a sufficiently small grid spacing ... -
Sensitivity analysis of the dynamic response of floating wind turbines
(Master thesis, 2018-08-23)Development of offshore wind turbines shows a clear shift from the fixed-bottom turbines to the floating turbines. The reason for such tendency is due to the fact that moving towards the deep ocean will substantially limit ... -
Sensitivity of Air-Sea Heat Exchange in Cold-Air Outbreaks to Model Resolution and Sea-Ice Distribution
(Journal article; Peer reviewed, 2021)Modeling air-sea interactions during cold air outbreaks poses a major challenge because of the vast range of scales and physical processes involved. Using the Polar WRF model, we investigate the sensitivity of downstream ... -
The sensitivity of marine-terminating glaciers to model parameters and geometry
(Master thesis, 2016-06-01)Greenland outlet glaciers are among the largest contributors to global sea level rise. With high velocities and calving rates, they discharge large amounts of glacial ice into the ocean. During the last two decades, the ... -
Sensitivity of remote sensing – derived phytoplankton productivity to mixed layer depth: Lessons from the carbon-based productivity model
(Peer reviewed; Journal article, 2009-10-01)Mixed layer depth (MLD) has long been recognized as having an important influence on underwater light budget and, thus, net primary productivity (NPP) of phytoplankton. The depth- and wavelength-integrated carbon-based ... -
Sensitivity of simulated wintertime Arctic atmosphere to vertical resolution in the ARPEGE/IFS model
(Journal article, 2008)The current state of the art general circulation models, including several of those used by the IPCC, show considerable disagreement in simulating present day high latitude climate. This is of major concern and reduces the ... -
