In 1976 a coloured 1:5 000 000 Gravity Map of Australia was published by BMR. At that stage the systematic reconnaissance gravity coverage of Australia, initiated by BMR in 1959, was complete, and preliminary gravity values were available from marine coverage of the continental shelf and margins. The map was based on approximately 260 000 gravity observations obtained by various organisations at a cost of about $12 000 000 from 300 surveys. It was produced using a CDC Cyber 76 computer system, Calcomp plotters and cartographic techniques. The computer processing phase took about four months and the cartography about three months. The coloured 1:25 000 000 Bouguer and free-air anomaly maps contained in this issue were also produced from the same data bank.
