The present state of work under the contract is reviewed. It is then shown that the drag coefficient over water is likely to be a function of fetch and wind duration. Observational data are analyzed to specify this relationship. The boundary layer over water is discussed. A double viscous sublayer characterizes the existing regime. Boundary layer separation appears to be a relatively rare event. The motion field has the character of a smooth flow over large parts of the sea surface. The investigation indicates that spray plays only a minor role in momentum transfer, at least at wind velocities below 10 meters per second. A theory has been established for the time-dependent depth and temperature of the midocean surface layer as a function of the interaction with the atmosphere. Large-scale circulation studies which include the effects of oceans on continent and the effects of seasons, were concluded. They will be resumed in a more sophisticated form at a later stage. Processing of Aruba data continues. Author
