‎First appearance of a this pioneer paper on ocean circulation and currents.""K. Zöppritz presents a theoretical treatment of drif currents in ""Hydrodynamische Probleme in Beziehung zur Theorie der Meeresströmungen."" (the paper offered). His neglect of the Coriolis force, which he attempted to justify onthe basis of the slowness of movements of ocean currents, leads to the conclusion that the wind-driven flow of the ocean is in the direction of the wind independent of the depth in the ocean, with a speed which decreases with depth. The model is revised by Vagn Ekman after Fridtjof Nansen notes the defelction to the right of wind-induced sea ice-drift ans speculates that the cause derives from the earth's rotation.""(Parkinson ""Breakthroughs"", 1878 E).‎
