Abstract: This paper is a theoretical and experimental investigation of the nature of oceanic velocity gradients.Starting with the equations of motion, equations governing the dynamic behavior of velocity gradients alongwith a first ...

Abstract: Observations of the motions of drifter clusters were made in the western Caribbean Sea during the summer of 1971. By two independent analyses of the relative motions of a cluster, two time series of horizontal divergence, ...

Abstract: Two long-term drifters were tracked for several months in the North Pacific as part of the NORPAX Pole experiment. The trajectories indicate at least one core of the North Pacific current was centered around 37N. Velocities ...

Abstract: The central question discussed here is how the rate at which drifter positions are determined and the position errors affect the calculation of velocity, acceleration and velocity gradients such as divergence and vorticity. ...

Abstract: In this paper steadily rotating modons that are trapped over topographic features with finite horizontal length scales are described. The quasigeostrophic equation over topography is transformed to a frame rotating with ...

Abstract: The response of the surface current to the wind has been described at various times by quadratic and linear laws. The quadratic response leads to Ekman-type currents while the linear response may be indicative of Stokes ...

Abstract: This is an analysis of the movement of six satellite-tracked (Nimbus 6) drifters which had lost their drogues. An attempt was made to correct the drifter velocity records for wind drag. The corrections, however, were ...

Abstract: A drifter was deployed in the Gulf Stream and tracked for 5 months by the Nimbus 6 satellite. From this experiment we have assessed the technical capability of the satellite fixing system for measuring ocean currents, the ...
