The test consisted of a total of 33 traverses over precisely located and calibrated test profiles established for this purpose. If errors are defined as the difference between surface and underwater values compared on a common datum, the mean LaCoste gravimeter error observed during a traverse varied from run‐to‐run to form a near normal distribution with mean of 1.8 mgal and standard deviation of 1.0 mgal. The corresponding statistics for the Askania are 2.1 mgal and 3.4 mgal, respectively, with the distribution markedly skew. The data were correlated with three components of accelerations as measured by the LaCoste and Romberg inertial platform. No significant correlation was evident for the LaCoste meter. Some correlation for the Graf‐Askania data, to which crosscoupling corrections are not normally applied, was observed.Read More
