Images: The Ocean—Captured in a Box

WHOI physical oceanographer Claudia Cenedese (left) and Rachel Bueno de Mesquita, a visiting researcher from the University of Rome, developed this laboratory experiment on a rotating table in the WHOI Geophysics Fluid Dynamics Laboratory to study fluid flow and eddies around seamounts.

This laboratory experiment simulates North Brazil Current Rings interacting with the Caribbean island chain. In the ocean, these eddies pinch off the North Brazilian Current and travel northwestward before hitting the Caribbean islands. In the laboratory, cold water from the melting ice cube sinks, creating swirling "eddies"?a technique devised by WHOI oceanographic experimentalist, Jack Whitehead. Dye drops on the ice cube make the eddies easier to observe. (Illustration by Jack Cook,Woods Hole Oceanographic Institution)

In a laboratory experiment, WHOI physical oceanographer Claudia Cenedese simulates some fluid dynamics that occur in the Arctic Ocean. The "box" rotates as the Earth does, and relatively fresh water forms a coastal current that hugs?and flows between?plastic "coastlines" representing Canada and Greenland. The dye lets scientists visualize and photograph the fluid behavior. (Illustration by Jack Cook, Woods Hole Oceanographic Institution)
