The objectives of Phase 2 were to record low and medium energy seismic data in selected areas and determine if that data could be used to established signatures that might indicate hydrates. We met the objectives, good data were recorded in the survey areas and features were identified which further establish a gas hydrate signature near hydrate core sites. Additional locations where the same signatures occurred were recommended for coring on future surveys. Geophysical data were collected in five separate areas. Initial work was in a transition zone extending from the continental shelf down the slope. Here we demonstrated that the equipment could provide information needed to identify features that could be used to establish a signature for gas hydrates in deep water. Additional areas were surveyed where gas hydrates had been identified in cores taken by Texas A M Oceanography Department. Isotopic analysis of these gas hydrate cores showed they were examples of two different types of origins, biogenic and thermogenic. Additional locations were identified where cores should be taken of future surveys to sample both types of gas hydrates. We also determined that high resolution sonar techniques employed on this survey could not resolve features on steep slopes in deep water. The paper describes the geological setting, equipment and instrumentation, methodology and results and a discussion of these results for the five areas. 6 refs., 18 figs.
