Rhodamine B dye was used to determine water circulation in Monterey Harbor. Point and line dye sources were traced visually, photographically, and by use of a fluorometer. The spreading of dye boundaries and the concentrations observed are presented in a time series of synoptic charts for each of the four surveys conducted. From these measurements, mean flow rates and a dye diffusion rate were determined. Circulation was found to be dominated by tidal currents, but wind-driven currents were important in the outer harbor. In the outer harbor, the circulation proved to be counterclockwise during rising tide, and clockwise during the falling tide. Flow was minimal in the inner harbor, or marina. Limited data indicate that the subsurface circulation agreed with the surface circulation in most of the surveys. Author
