Scaling the decay of turbulence kinetic energy in the free-convective boundary layer
(Peer reviewed; Journal article, 2019)We investigate the scaling for decaying turbulence kinetic energy(TKE) in the free-convective boundary layer, from the time the surface heat flux starts decaying, until a few hours after it has vanished. We conduct a set ... -
Sea ice cover in Isfjorden and Hornsund, Svalbard (2000–2014) from remote sensing data
(Peer reviewed; Journal article, 2016-01-19)A satellite database including 16 555 satellite images and ice charts displaying the area of Isfjorden, Hornsund, and the Svalbard region has been established with focus on the time period 2000–2014. 3319 manual interpretations ... -
Sea ice thermohaline dynamics and biogeochemistry in the Arctic Ocean: Empirical and model results
(Peer reviewed; Journal article, 2017-07)Large changes in the sea ice regime of the Arctic Ocean have occurred over the last decades justifying the development of models to forecast sea ice physics and biogeochemistry. The main goal of this study is to evaluate ... -
Sea ice velocity in the Fram Strait monitored by moored instruments
(Peer reviewed; Journal article, 2003-10-04)The Fram Strait sea ice velocity was measured by means of a new method using moored Doppler Current Meters in the period 1996–2000. Almost 3 years of ice velocity observations near 79N 5W are analyzed. The average southward ... -
Sea level variation in the Red Sea based on SODA data
(Master thesis, 2012-10-01)In this study we investigate the sea level variation in the Red Sea focusing on wind stress setup. 50-years dataset from 1957 to 2007 of sea level and wind stress from Simple Ocean Data Assimilation (SODA) data version ... -
Sea surface gravity wave - wind interaction in the marine atmospheric boundary layer
(Peer reviewed; Journal article, 2014)In this study, we investigate the turbulence structure over idealized wind-generated surface gravity waves with varying wave age using a wave-modified one-dimensional boundary layer model. To prescribe the shape of the ... -
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 ... -
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 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 ... -
