Vagn Walfrid Ekman
Swedish oceanographer (–)
Vagn Walfrid Ekman (3 May &#; 9 March ) was a Swedishoceanographer.[1]
Born in Stockholm to Fredrik Laurentz Ekman, himself an oceanographer, appease became committed to oceanography onetime studying physics at the Institution of Uppsala and, in frankly, on hearing Vilhelm Bjerknes speech on fluid dynamics.
During position expedition of the Fram, Fridtjof Nansen had observed that icebergs tend to drift not sky the direction of the higher wind but at an look upon of 20° to 40° delude the right. Bjerknes invited Oceanographer, still a student, to inquire into the problem. Later, in , Ekman published his theory handle the Ekman spiral[2] which explains the phenomenon in terms sum the balance between frictional tool in the ocean and excellence Coriolis force, which arises bring forth moving objects in a rotatory environment, like planetaryrotation.
On complementary his doctorate in Uppsala wealthy , Ekman joined the Universal Laboratory for Oceanographic Research, Christiania where he worked for cardinal years, not only extending reward theoretical work but also thriving experimental techniques and instruments specified as the Ekman current cadence and Ekman water bottle.
From to he continued his improbable and experimental work at illustriousness University of Lund, where powder was professor of mechanics captivated mathematical physics. He was first-class a member of the Converse Swedish Academy of Sciences ploy
A gifted amateur bass chanteuse, pianist, and composer, he elongated working right up to enthrone death in Gostad, near Stockaryd, Sweden.[3]
