Abstract
In August 1989, a geophysical survey in parts of the Exclusive Economic Zones of Vanuatu, Solomon Islands, Fiji, Tonga, and Western Samoa was conducted using a variety of techniques including GLORIA sidescan sonar, Seabeam wide-swath bathymetry, 3.5-kHz subbottom profiling, and dual-channel seismic reflection profiling. The data obtained are relevant to significant regional geotectonic problems, and their interpretation has helped to clarify some of these problems, identify areas where potential mineral deposits may be expected to occur, and in some cases, where geohazards may exist on the sea floor. The survey is described in this contribution, and the following papers in this special issue interpret the results of this work.
