The Applied Oceanography group
performs field, laboratory and theoretical investigations of hydro-thermodynamic processes and turbulence in ice adjacent sea water layers and near fronts of outflow glaciers, propagation of surface and internal waves in ice covered waters, properties of tide induced currents in the Svalbard region and in the Barents Sea. CTD and ADCP profiling, ADV turbulent measurements, tide measurements are performed during boat cruises in ice free and ice seasons. Laboratory works includes experiments in wave tank and ice tank at UNIS. Theoretical investigations and numerical simulations are focused on the modeling of wave propagation in ice covered waters, wave actions on floating ice, modeling of tidal currents in navigational straits, and modeling of hydro-thermodynamic processes inside ridge keels and around icebergs keels.

Current research project:

Experiments on waves in oil and ice, 2014–2016 (WAVES)

WAVES is hosted by University of Oslo and funded by the Research Council of Norway.
The project will provide experimental data from the laboratory and the field, which can be used to validate existing theories pertaining to wave damping caused by flexible surface covers (due to elastic surface films, oil slicks or grease ice), wave dependent fluxes of momentum and energy, wave-induced currents in the presence of flexible surface covers, for example the wave-induced drift of oil slicks or the streaming beneath sea ice caused by incoming swell.

Project leader is professor Atle Jensen (UiO). UNIS professor Aleksey Marchenko is leader of the UNIS group.
