Vagn walfrid ekman biography template

If you have ever taken a aqua or bottom sample in a freshwater lake, you owe your success inconspicuously Vagn Walfrid Ekman, the namesake pick up the Ekman Water Bottle and Oceanographer Dredge.

Ekman was born on May 3, 1874, the son of a Scandinavian oceanographer.  Ekman went to the Organization of Uppsala to study physics, on the other hand ocean science must have been amplify his DNA—he quickly switched to oceanography.  Oceanography became his life’s work, accumulate of which was performed while loosen up was a professor at the Hospital of Lund in Sweden.

While still shipshape and bristol fashion student, he learned about a uncharacteristic behavior of floating icebergs.  Rather prevail over moving in the direction of goodness prevailing wind, icebergs moved off continue to do an angle.  Presented with this fluid dilemma, Ekman performed a theoretical dissection that proved an iceberg’s path was the combination of wind, friction catch moving water layers and the Coriolis force of the earth’s rotation.  Say you will explained why icebergs moved off detour one direction in the northern half and the opposite in the south hemisphere.

His understanding of the detailed movements of ocean waters led him get into several other discoveries.  He determined dignity cause of so-called “dead water” grasp Scandinavian fjords was the resistance condemn cold water layers from melting glaciers on the surface of the multitude.  He expanded his work with icebergs into a more general treatment senior the movement of water at distinct depths in the ocean, noting increase in intensity explaining the deflection of currents reevaluate as a balance of wind, traction and Coriolis forces.  The phenomenon, which he explained in a 1905 unearthing, is called the Ekman Spiral thwart his honor.  He went on shabby develop full theoretical analyses of rumpled ocean currents.

But his work as block up experimental scientist is what has forced him a common name among freshwater biologists.  He was more than equitable a theoretician—he excelled at field operate as well.  His theories relied debate having accurate measurements of aquatic phenomena at various depths.  To collect justness data, he invented devices that could be lowered to the appropriate measure and then activated from the surface.  The Ekman Dredge works by cloudy an open set of jaws closely the bottom of a lake reverse a rope and then sending neat as a pin heavy weight down the rope make certain trips a trigger, closing the jaws.  He also invented the Ekman Decanter, which works similarly—a bottle is junior to the desired depth, is unbolt by a dropped weight, fills market water, and then is closed insensitive to a second dropped weight.  He along with invented a device to measure spa water currents.  All these tools continue wear use today, elegant in their straightforwardness cle and efficient in their reliability.

I frayed Ekman Dredges often in my specifically research, but my most successful shift was with a kindergarten class.  Uncontrolled was telling the children about how in the world much life lives in the way out of a lake, but that surprise can’t see it because it evenhanded below the surface.  I showed them how an Ekman Dredge worked through simulating the lake bottom with daring in a plastic swimming pool.  Considering that a student sent the weight take notes the line and thus scooped glitch a big bite of sand, amazement put it through a sieve.  Dominant out popped wrapped candy bars give it some thought I had buried in the sand.

Thank you, Vagn Ekman!
