    Description / Table of Contents: Summary A buoy with stabilized mast is used for the determination of the vertical eddy transports above the sea. An accuracy of the stabilization of 1° is obtained by servo mechanism and reference to a gyro. The buoy is of small size (1.5m diameter, 4.5 m draught), light weight (700 kg including stabilization unit) and short period of dip motions (1.7 sec). In use, the buoy is connected with a research vessel by floating cables. The system was used in the Baltic with wind strength up to 8 Beaufort. For comparison a tripod is available which provides a fixed point over water of 14 m depth. Some results of determination of stress and heat flux are given. These may be summarized by a drag coefficient ℵ10 = 1.2 · 10-3 and a similarly defined heat transport coefficient of 1·10−3.
    Notes: Zusammenfassung Für Fluktuationsmessungen auf See wird eine Boje mit aktiv neigungsstabilisiertem Mast benutzt. Die Neigungsstabilisierung arbeitet genauer als 1°. Die Boje ist gekennzeichnet durch kleine Abmessungen, geringes Gewicht und kurze Tauchschwingungsperiode. Sie ist für den Einsatz auf offener See von einem Forschungsschiff aus konzipiert. Messungen waren auf der Ostsee bis Windstärke 8 Beaufort möglich. Für Vergleichsmessungen wurde ein feststehendes Meßgerüst benutzt. Als Beispiel werden direkte Messungen des vertikalen Impuls- und Wärmeflusses wiedergegeben, die durch einen Reibungskoeffizienten ℵ10 = 1,2 · 10-3 und einen entsprechenden Wärmetransportkoeffizienten von 1·10−3 gekennzeichnet werden können.

    Notes: Abstract The deviation of the sea surface temperature from the water temperature below is calculated as a function of the heat flow through the air-sea interface, using wind tunnel determinations of the effective thermal diffusivity in a boundary layer. The influence ofQ, shortwave radiation, andH, latent and sensible heat transfer plus effective back radiation, and U, wind speed, can be described by:T 0 −T w =C 1 ·H/U +C 2 ·Q/U. The calculated coefficients vary slightly with reference depth, Tables II and III. They are in good agreement with independent observations.

    Notes: Abstract The theoretical developments yielding the resistance law for the planetary boundary layer are summarized, including the refinements of the ageostrophic method. This leads to the hypothesis that the resistance law for the simple non-stationary, advective boundary layer is obtained from the one for a stationary, horizontally homogeneous boundary layer, if the modulous of the geostrophic wind in the latter is replaced with a generalized frictionless wind in the former. The generalized frictionless wind includes the inertial terms.

    Notes: Abstract Geostrophic drag coefficients are obtained from direct measurements of the momentum flux and from an objective analysis of the synoptic pressure field by the method of least squares. At a site in the Kiel Bight, a mean geostrophic drag coefficient c g = 0.0223 was obtained with near neutral/ slightly unstable conditions and a surface Rossby Number of 1.2 × 109.
