  • Description:
    "The Coastal and Estuarine Oceanography Branch of NOAA’s National Ocean Service deployed four acoustic Doppler current profilers in San Francisco Bay from April 28 to May 29,1992, in the field phase of a Quality Assurance miniproject. A QA miniproject is a relatively inexpensive method used to evaluate the quality of published NOAA tidal current predictions by comparing them with new data from a small number of high technology instruments using an objective statistical evaluation of the differences between observed and predicted currents. The miniproject was conducted in response to concerns expressed by the Harbor Safety Committee ofthe San Francisco Bay region that NOAA Tidal Current Table predictions do not accurately represent actual conditions in the Bay at several locations. These data were analyzed and compared with 1992 NOAA Tidal Current Table predictions at the deployment sites. Historical data from the 1979-1980 NOAA-USGS (U.S. Geological Survey) survey were re-analyzed and compared with present predictionsthatwere hindcastto the times ofdata collection. Thisreport summarizesthe 1992 data collected and compares both the 1992 data and the 1979-80 survey data with NOAA Tidal Current Table predictions. Recommendations based on this analysis for improved current information for the Bay include development of new reference stations at Golden Gate Bridge and Carquinez Strait, new analysis of the 1979-80 survey data, reoccupation of selected stations, development of a numerical hydrodynamic model, development of a model-based current circulation atlas and digital prediction products, and deployment of a physical oceanographic real-time system (PORTS)."
