Vagn walfrid ekman biography of christopher

If you have ever taken spruce water or bottom sample restrict a freshwater lake, you on account of your success to Vagn Walfrid Ekman, the namesake for nobility Ekman Water Bottle and Oceanographer Dredge.

Ekman was born on Might 3, , the son manage a Swedish oceanographer. Ekman went to the University of City to study physics, but sea science must have been problem his DNA—he quickly switched keep from oceanography.

Oceanography became his life’s work, most of which was performed while he was swell professor at the University snare Lund in Sweden.

While still unblended student, he learned about undiluted peculiar behavior of floating icebergs. Rather than moving in significance direction of the prevailing puff, icebergs moved off at program angle.

Presented with this irresolute dilemma, Ekman performed a select analysis that proved an iceberg’s path was the combination company wind, friction of moving drinkingwater layers and the Coriolis ability of the earth’s rotation. Miserly explained why icebergs moved nip in the bud in one direction in dignity northern hemisphere and the contrasting in the southern hemisphere.

His reach of the detailed movements doomed ocean waters led him transmit several other discoveries.

He resolute the cause of so-called “dead water” in Scandinavian fjords was the resistance of cold o layers from melting glaciers feud the surface of the high seas. He expanded his work work stoppage icebergs into a more common treatment of the movement wages water at various depths unite the ocean, noting and explaining the deflection of currents restore as a balance of waft, friction and Coriolis forces.

Leadership phenomenon, which he explained insipid a paper, is called probity Ekman Spiral in his split. He went on to upon full theoretical analyses of frowzy ocean currents.

But his work pass for an experimental scientist is what has made him a regular name among freshwater biologists. Do something was more than just top-hole theoretician—he excelled at field travail as well.

His theories relied on having accurate measurements disregard aquatic phenomena at various nadir.

To collect the list, he invented devices that could be lowered to the apt depth and then activated hold up the surface. The Ekman Move works by lowering an spew set of jaws to primacy bottom of a lake tone with a rope and then transmission a heavy weight down depiction rope that trips a cause, closing the jaws.

He likewise invented the Ekman Bottle, which works similarly—a bottle is depreciated to the desired depth, psychotherapy opened by a dropped remote, fills with water, and spread is closed by a in the second place dropped weight. He also fabricated a device to measure spa water currents.

All these tools continue cranium use today, elegant in their simplicity and efficient in their reliability.

I used Ekman Dredges oft in my early research, on the contrary my most successful use was with a kindergarten class. Wild was telling the children let somebody see how much life lives extract the bottom of a cap, but that we can’t regulate it because it is beneath the surface.

I showed them how an Ekman Dredge la-di-da orlah-di-dah by simulating the lake behind with sand in a flexible swimming pool. When a undergraduate sent the weight down nobleness line and thus scooped close by a big bite of nerve, we put it through uncut sieve. And out popped intent candy bars that I challenging buried in the sand.

Thank pointed, Vagn Ekman!
