Gravity Base Station Descriptions.

Descriptions of gravity base stations occupied by the Woods Hole Oceanographic Institution during the years 1962 through September 1973 are presented. The measurements were made with LaCoste and Romberg Geodtic Gravity Meter No. G-18. The gravity values, in the Potsdam System, given for these stations are for the most part based on a value of 980326.04 at station 317 in Woods Hole, which is based on a value of 980118.00 for the National COMMERCE gravity base in Washington, D.C. For those stations for which IGSN 71 values are available, the differences between the IGSN 71 values and the G-18 values have a mean of -13.34 mgal, a standard deviation of 0.64 mgal, a median of 13.53 mgal, and an RMS of 13.36 mgal. The internationally adopted difference between the IGSN 71 System and the Potsdam System is -14.00 mgal. Author
