Abstract or Summary
  • The effects of five data processing methods on the accuracy of geostrophic computations are analyzed using hydrographic data collected from a set of 24 hour triangular stations off the Oregon coast. Sources of error are assessed by comparison with an available in situ Salinity/Temperature/Depth record (STD) trace at a control station. The results of this study show that the accuracy of the dynamic depth anomaly depends on the choice of vertical integration intervals based on sea water density distribution instead of on an arbitrary set of standard depths for all the cases and that the effect of interpolation of hydro- data is not significant if the data is properly sampled and adequately interpolated. Some sources of error in computations of geostrophic currents from hydrographic data can be alleviated by proper sampling and processing procedures. They are (1) the sampling errors caused by improper sampling schemes which miss the sharp features and periodic variations (i. e. internal waves) in the ocean, and (2) processing errors caused by improper interpolations of data and determinations of mean density.
