Abstract
Description
During the fifties, there was an apparent pause in activity in field experiments of diffusion in the ocean, except for research on large-scale mixing by measuring radioactivity in the ocean from fission products, mostly by Japanese oceanographers, and from natural radioisotopes by groups of geochemists of the Lamont Geological Observatory and Scripps Institution of Oceanography. In the late fifties, Pritchard and his co-workers at the Johns Hopkins University developed a tracer technique using harmless organic dye which can be traced with a ship borne fluorometer with concentration sensitivity comparable to the radioactive tracer. A group at Lamont Observatory has fully utilized this technique in various parts of the ocean other than estuaries for which the technique was originally developed, and it is now in the process of modifying the technique for use in the deep ocean. More recently, a national program for conservation of natural resources stimulated studies of pollution of the seas and fresh waters around the country and the dye technique has been extensively utilized in various areas by different organizations. The main purpose of the present symposium were to exchange information on field techniques for measuring diffusion developed mathematical models of diffusion in oceans, lakes and rivers, and to coordinate and promote further studies undertaken in various institutions.
