Puget Sound Approaches Circulatory Survey

During the period from the fall of 1973 through the fall of 1976, a seven-phase circulatory survey was carried out by the National Ocean Survey (NOS) in the waters of the Strait of Juan de Fuca, Haro and Rosario Straits, and the Strait of Georgia, referred to collectively as Puget Sound Approaches. Extensive and detailed measurements were made of currents, tides, and the temperature and salinity of the water, along with additional measurements of various atmospheric parameters, such as wind speed and direction, sea-level pressure, and air temperature. This report provides details about this survey including locations of stations, time periods of occupation, instrumentation, sampling rates, and data processing techniques; numerous charts and tables are provided. Also included is a chapter summarizing all current and tide data taken by NOS in this area prior to the present survey. 1980 NOS (National Ocean Service) Library Public Domain 1936
