  • Name: Richardsons Shipdrift
  • Description - Shipdrifts are indirect determinations of ocean surface currents based on the ship drift method. In this method, the difference between a ship's dead-reckoned position determined from its previous position and from a navigational fix is ascribed solely to the effect of surface currents. The date, data source, position and current direction and speed are recorded for each observation. Richardsons Shipdrift represents his own analysis or derivation of the World Historical Spindrifts Archives.
