Abstract : Temperature and salinity measurement errors introduced into the equations used for dynamic computations may result in errors exceeding the dynamic height difference value used subsequently to determine currents. The measurement error is usually accompanied by an interpolation error introduced when observed values of an oceanographic cast are scaled to standard depths. The magnitude of the possible error in dynamic height is de pendent upon the temperature, depth, and the accepted accuracy of temperature and salinity measurements. The salinity range sampled produces a negligible error. The greater the measured temperature or depth, the greater the resulting error may be. The recognition of the possible magnitude of this error is important for the proper interpretation of computed dynamics and for fixing the assumed depth of no-motion. (Author)
