Helland-Hansen and, like them, must be ranked as one of the great oceanographers. Ekman was the youngest son of Fredrik Laurentz Ekman, a professor who also worked in oceanography. He went to school in Stockholm and then studied at the University of Uppsala.

The original idea of the spiral came from Nansen, who observed a systematic drift of the ice to the right of the wind direction during his famous Frame expedition. Nansen duggested that Ekman investigate the problem mathematically, resoning that each layer of the sea must be set in motion by the layer immediately above and be successively more deflected to the right by the Coriolis force on the northern hemisphere.

Its importance has since been well established. Another important theoretical contribution was given in a paper published in in the same journal. Here Ekman developed, for the first time, a complete mathematical theory for the wind-driven circulation in an oceanic basin.

Both the and the papers are masterpieces of clarity and elegance and can certainly be enjoyed by all those interested on the subject, whether professionally or not. The first paper has been reprinted in booklet form by the Royal Swedish Academy of Sciences, Stock-holm, and there are plans to print an English edition of the second paper.

He made determinations of the equation state for seawater and studied several important hydrodynamic phenomena both in the widly known of his studies is that devoted to dead water, the most of his studies is that devoted to dead water, the strong resistance experienced by ships in the Norweigan fjords because of a particular stratification of the water.

Ekman also constructed oceanographic instruments.

His current meter, which gives speed and direction by use of a purely mechanical system, is still a standered tool in oceanographic studies. Later, inhe cruised to the trade-wind belt in the Atlantic to carry out systematic current measurements. StockholmSweden. See also [ edit ]. References [ edit ]. Nationalencyklopedin in Swedish.
