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 ... -
Sea surface pCO2 variability and air-sea CO2 exchange in the coastal Sudanese Red Sea
(Journal article; Peer reviewed, 2021)The dynamics of sea surface pCO2 (pCO2w) and air–sea CO2 exchange of the Sudanese coastal Red Sea has for the first time been studied over a full annual cycle (October 2014–October 2015) based on semi-continuous measurements ... -
Sea Surface Temperature and Ocean Heat Content during Tropical Cyclones Pam (2015) and Winston (2016) in the Southwest Pacific Region
(Journal article; Peer reviewed, 2021)The sea surface temperature (SST) and upper ocean heat content (OHC) have been explored along the track of two tropical cyclones (TCs), TC Pam (2015) and TC Winston (2016). These TCs severely affected the islands of Vanuatu ... -
Sea-level change over the northern European continental shelf due to atmospheric and oceanic contributions
(Doctoral thesis, 2022-09-02)Global mean sea level (GMSL) is a key indicator of climate change as it comprises information on different components of the climate system. However, despite its importance for climate and society, GMSL cannot be used for ... -
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 ... -
