Abstract : An automatic sea gravity system utilizing a digital computer was designed and developed in an effort to reduce the time required to bring together the pertinent information for the computation of gravity values, to reduce the time required for the computations themselves, and to make results available for interpretation, planning, and checking purposes aboard ship while the cruise is in progress. The system consists of: a LaCoste and Romberg Sea Gravity Meter, data conversion units for computer compatibility with the gravity meter, ship's gyrocompass and ship's speed log, an IBM 1710 mod 1 Control System (the combination of a 1620 Computer and a 1711 Data Converter for analog to digital conversion), and typewriter and paper tape input-output units.
