Although most of the observation of currents have been made at sea, the Institute has developed one remarkable instrument to predict ocean currents right in the laboratory. This apparatus consists of a large parabaloid bowl on which the outlines of the continents are raised. The bowl is set on a drive shaft that rotates it rapidly and evenly, while from four sides a battery of Kenmore vacuum cleaners blows a steady supply of "trade winds" late the hemisphere. The procedure into pour water into the bottom of the rotating parabaloid while centrifical force spreads it into an even sheet that...
...when the Atlantic is becoming in the eyes of some Airlines a "glorified puddle" the oceanographers have turned back to this "puddle" to seek in its depths some of the closest secrets of the earth.George A. HermannScientist (upper left) surveys small accurate scale currents formed in spinning parabaloid bowl as nozzle at right blows air into water. Workman (above) is shown adjusting a newly designed Nansen bottle for gathering selected samples of water from the depths. Observers (lower left) watch special experiment in bowl and (below) watch growing micro organisms in multicolored tanks...
