Diffusion of a Vertical Sheet in the Open Ocean

Abstract

In a previous experiment (Miranda, Schimmel, and Rooney, Hudson Laboratories Tech. Rept. No. 87, April 6, 1961), mass transport in the wake of a submerged submarine was studied. Results indicated that after the initial few minutes local turbulence induced by the ship's screws was of relatively minor importance in the spreading. Ordinary oceanic turbulence appeared to be the dominant mechanism. An experiment was designed to test this hypothesis: A thin, vertical sheet of radiotracer was dispensed from a towed line source. The marked waters were probed, as in the prior experiment, by a towed, vertical array of scintillation counters. The similarity of the diffusion patterns from the two experiments strongly supports the above hypothesis.
