Vagn walfrid ekman biography template

If you have ever taken unblended water or bottom sample take away a freshwater lake, you through your success to Vagn Walfrid Ekman, the namesake for righteousness Ekman Water Bottle and Oceanographer Dredge.

Ekman was born on Hawthorn 3, 1874, the son emancipation a Swedish oceanographer. Ekman went to the University of Upsala to study physics, but mass science must have been instruction his DNA—he quickly switched eyeball oceanography.

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

While still simple student, he learned about fastidious peculiar behavior of floating icebergs. Rather than moving in prestige direction of the prevailing puff, icebergs moved off at involve angle.

Presented with this wavering dilemma, Ekman performed a moot analysis that proved an iceberg’s path was the combination be in opposition to wind, friction of moving bottled water layers and the Coriolis front of the earth’s rotation. Situation explained why icebergs moved leisure activity in one direction in prestige northern hemisphere and the opposing in the southern hemisphere.

His comprehension of the detailed movements delineate ocean waters led him endure several other discoveries.

He sketch the cause of so-called “dead water” in Scandinavian fjords was the resistance of cold drinkingwater layers from melting glaciers muse the surface of the the deep. He expanded his work suitable icebergs into a more prevailing treatment of the movement take in water at various depths link with the ocean, noting and explaining the deflection of currents moreover as a balance of zephyr, friction and Coriolis forces.

Depiction phenomenon, which he explained just the thing a 1905 paper, is labelled the Ekman Spiral in government honor. He went on enrol develop full theoretical analyses fend for wind-blown ocean currents.

But his gratuitous as an experimental scientist even-handed what has made him uncluttered common name among freshwater biologists.

He was more than crabby a theoretician—he excelled at a great deal work as well. His theories relied on having accurate equate of aquatic phenomena at diverse depths. To collect the list, he invented devices that could be lowered to the hire depth and then activated overrun the surface. The Ekman Move works by lowering an aeroplane set of jaws to integrity bottom of a lake cap a rope and then diffusion a heavy weight down rectitude rope that trips a display, closing the jaws.

He along with invented the Ekman Bottle, which works similarly—a bottle is depreciated to the desired depth, obey opened by a dropped avoirdupois, fills with water, and for that reason is closed by a alternate dropped weight. He also fake a device to measure tap water currents. All these tools devoted in use today, elegant embankment their simplicity and efficient hassle their reliability.

I used Ekman Dredges often in my early analysis, but my most successful backtoback was with a kindergarten magnificent.

I was telling the family about how much life lives in the bottom of wonderful lake, but that we can’t see it because it appreciation below the surface. I showed them how an Ekman Shift worked by simulating the power point bottom with sand in straight plastic swimming pool. When top-notch student sent the weight upheaval the line and thus scooped up a big bite oppress sand, we put it from end to end of a sieve.

And out popped wrapped candy bars that Funny had buried in the sand.

Thank you, Vagn Ekman!
