Between 1967 and 1913 aeromagnetic surveys were flown over eastern Papua New Guinea, but the results only became available during the country’s transition to full independence. Overlooked at the time, they now seem to have been largely forgotten
The Internet is a treasure trove for the early publications on the Uranie voyage but, like all good hidden treasures, there are many obstacles to their retrieval.

The availability of very detailed topographic grids has provided geologists of new ways of looking at areas. Sometimes the results can be spectacular.
