Satellite and Ground Observations of Snow Cover in Tibet during 2001–2015
(Peer reviewed; Journal article, 2017-11-22)The seasonal snow cover of the Tibetan Plateau exerts a profound environmental influence both regionally and globally. Daily observations of snow depth at 37 meteorological stations in Tibet and MODIS eight-day snow products ... -
A Satellite Era Warming Hole in the Equatorial Atlantic Ocean
(Journal article; Peer reviewed, 2020)Observations during the satellite era 1979–2018 only depict small sea surface temperature (SST) trends over the Equatorial Atlantic cold tongue region in boreal summer. This lack of surface warming of the cold tongue, ... -
Satellite monitoring of algal blooms in Norwegian coastal waters

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 ... -
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-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 ... -

(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 ... -
