SOFIA 1992 during ASTEX was devoted to air-sea interactions and energy transfer study across the surface of the ocean. During SOFIA/ASTEX different shipborne instruments were indeed used to determine fluxes at the surface and to analyze the structure of the atmospheric marine Boundary layer MABL. A ten meters height mast with a 3 D sonic anemometer from the Rennell center was used in front of the ship and also fast measurement of temperature and humidity were performed by university of Washington on a boom in front of the ship. These instruments were utilized with the inertial-dissipative method to get fluxes to be compared with bulk fluxes and to establish drag coefficients as Cd. Other measurements were performed at different locations on the ship at the deck of the ship with classical temperature, humidity and wind devices, from an instrumented tethered balloon launched at the stern of the ship and from a Doppler minisodar in front of the ship. All the fluxes estimates with the different instruments were conducted during conditions of navigation in front of the mean wind at a slow speed. After a brief introduction on the relationship between the ship wake effect in the atmospheric surface layer, the influence of the ship aerodynamic perturbation on the surface fluxes estimates is discussed.
