Air-Sea fluxes during the EUREC4A2020 Experiment Open
The EUREC4A experiment was conducted in January and February 2020 off the North-Eastern coast of the Barbados Island. Air-Sea fluxes and bulk variables were derived from in situ measurements performed at the top of a bow mast on the Ifreme…

Estimation of the Eddy Viscosity Profile in the Sea Surface Boundary Layer from Underway ADCP Observations Open
A method of assessing the mean eddy viscosity profile (EVP) in the sea surface boundary layer (SBL) under variable wind conditions is proposed. Performance of the method is tested using observations by an ADCP-equipped platform in the coas…
