TURBULENT DIFFUSION IN THE INTERMEDIATE WATERS OF THE NORTH PACIFIC OCEAN,
Abstract
A field experiment to measure turbulent diffusion in stable intermediate water was conducted in the Kauai channel off the island of Oahu, Hawaii, in the spring of 1968. 122,000 grams of Rhodamine BMG dye were injected with neutral buoyancy at a depth of 300 meters. The growth of the dye pool was followed for over 72 hours with towed pumping systems coupled to on-deck fluorometers. A complete description of the pool was obtained 46.5 hours after injection. Application of the data to existing theoretical models describing concentration distributions resulted in calculated characteristic parameters of energy dissipation, after Okubo, of .0066 sq cm/sec and diffusion velocity, after Joseph and Sendner, of 0.13 cm/sec. Vertical transport was extremely slow, the pool remaining approximately 2 meters thick throughout the experiment. (Author)
