Caption from Down to the Sea for Science, Pg. 81:
Bill von Arx and Henry Stommel developed a new and powerful method of observing surface currents from a ship under way. It depended on the electric potentials induced by the movement of the water through the earth's magnetic field. In this 1948 Med cruise photo, the men in the foreground (from left, James Hollis, Gene Krance, Dean Bumpus, and Hans Cook) watch the readout from the geoelectromagnetokinetograph, known as the GEK (pronounced "geek"). Nat Corwin launches a mechanical Watson current meter aft, with Dave Owen photographing him.
