UR.lcr85"~ 56 1985/58. West Coast gravity tie stations
R.G. Richardson M.J. Dix This report presents absolute gravity values for a series of tie stations on the west coast of Tasmania. Intervals were measured using Worden gravity meter W913 and Sodin gravity meter S183 with a minimum of six measurements of each interval. The measured interval between Hobart Airport and Strahan Airport was in error by 2.1 ~m/sec2 and between Strahan and Smithton Airports was in error by 0.2 ~/sec2. All observed gravity values have an error of less than 1 ~/sec2.
The observed gravity values are given in Table I and the station locations are shown on Figure 1.
