Abstract

Evidence for shallow gas has been derived from geophysical and field data during a marine survey in the Arafura Sea (SS05/2005). Sub-bottom profile evidence includes enhanced reflections, acoustic blanking, phase reversal and low frequency events. These geophysical attributes have been studied within staged post processing. This has allowed the identification of areas within various parts of the section at depths between 1 to ~70m below sea floor. This evidence has been correlated with side-scan sonar and multi-beam with pockmark fields and mud domes identified over areas of interpreted sub-surface gas.
