Marstein field cruise
The ocean and meteorological group at the Geophysical Institute, University of Bergen, undertook a 7-day field campaign aboard the research vessel RV Håkon Mosby last November. The cruise took place at Marstein Fyr outside Bergen and was aimed to gather data on turbulent air-sea interaction processes during different sea states and wind speeds. The campaign involved the mooring of a Met-ocean Wavescan buoy that has been equipped with one of the NORCOWE Direct Covariance Flux systems.
The atmospheric instrumentation provided high frequency wind speed and temperature measurements for the acquisition of near-surface turbulent heat and momentum fluxes. A microstructure profiler, a moored autonomous turbulence system and a bottom fixed acoustic wave sensor have been deployed in the vicinity of the buoy to obtain dissipation rates of turbulent kinetic energy and turbulent momentum fluxes below the sea surface. These measurements enable GFI researchers to distinctly improve our understanding of complex small-scale turbulent air-sea interaction processes such as turbulent mixing in the water column and atmosphere-wave interactions.
