Abstract:	The available methods for estimation of wind currents, mass transport velocity by waves and permanent flow (thermohaline gradient current) are briefly summarized and a simplified computer approach is outlined. The computer synoptic surface currents are compared with monthly mean current charts and with surface wind conditions. This analysis indicates that the surface currents are greatly wind-driven. A detailed verification procedure which will use a the observed changes in sea surface temperature is outlined. The use of the synoptic current fields for computation of divergence and convergence and the resulting changes in subsurface thermal structure is described. The relative importance of the synoptic surface currents in ship routing, rescue operations and other practices is reviewed.
