Abstract The addition of offshore wind farms (OWFs) to stratified regions shelf seas poses an anthropogenic source turbulence, in which the foundation structures remove power from oceanic flow that is fed into turbulent mixing wake downstream. loss stratification within a single OWF structure observed for first time by means field observations, enable qualitative characterization disturbed These results are complemented with high‐resolution large eddy simulations four different strengths...
Abstract The seasonal thermocline in shallow shelf seas acts as a natural barrier for boundary‐generated turbulence, damping scalar transport to the upper regions of water column and controlling primary production certain extent. To better understand turbulence mixing conditions within thermocline, two unique 12 17 day data sets with continuous measurements dissipation rate turbulent kinetic energy ( ɛ ) collected by autonomous underwater gliders under stratified well‐mixed are presented. A...
Abstract Storms are infrequent, intense, physical forcing events that represent a potentially significant driver of ocean ecosystems. The objective this study was to assess changes in water column structure and turbulent fluxes caused by storms using an autonomous underwater glider, as well the chlorophyll (Chl ) response altered environment. glider able measure throughout complete life cycle Storm Bertha it passed over North Sea August 2014, from its arrival dissipation. triggered rapid...
Abstract Narrow baroclinic fronts are observed in the surface mixed layer (SML) of Baltic Sea following an autumn storm. The subjected to hydrodynamic instabilities that lead submesoscale and turbulent motions while restratifying SML. We describe observations from ocean glider combines currents, stratification, turbulence microstructure a high horizontal resolution (150–300 m) analyze such fronts. show SML is strongly modulated by frontal activity, acting as both source sink for kinetic...
Abstract The quantification of pressure fields in the airflow over water waves is fundamental for understanding coupling atmosphere and ocean. relationship between field surface slope velocity are crucial setting fluxes momentum energy. However, quantifying these hampered by difficulties measuring at wavy air–water interface. Here we utilize results from laboratory experiments wind-driven waves. data consist particle image velocimetry combined with laser-induced fluorescence surface. These...
<p>The North Sea is a world-wide hot-spot in offshore wind energy production and installed capacity rapidly increasing. Current potential future developments raise concerns about the implications for environment ecosystem. Offshore farms change physical across scales various ways, which have to modify biogeochemical fluxes ecosystem structure. The foundations of cause oceanic wakes sediment into water column. Oceanic spatial O(1km) structure local ecosystems within vicinity...
