The East Siberian cruise of the USS Burton Island (AGB-1) offered a unique opportunity to obtain turbidimetric measurements inexpensively on a cooperative basis. In addition to routine oceanographic data obtained during the cruise, personnel of the U. S. Navy Oceanographic Office obtained turbidity data on many of the water samples taken during the survey. The measurements were made with a Hellige turbidimeter furnished by the U. S. Naval Research Laboratory. The purpose of this effort was to obtain data on the time and spatial stability of particulate material in the sea in various locations. Other research is bearing out evidence that turbidity layers are also sound-scattering layers and may play a basic role in acoustic volume reverberations. The turbidity profiles of the various locations and other oceanographic data such as temperature and density presented in this report are thus part of a more comprehensive program aimed toward understanding the ocean environment. The results showed relatively high levels of turbidity which could change rapidly with time. These observations can be explained by the relative shallowness in the area, turbidity currents from the Kolyma River, and the dirty ice conditions which existed. (Author)
