Data Type(s): Seismics: Air Gun / Water Gun, Seismics: Boomer, Seismics: Bubble Gun, Seismics: Sparker, Seismics: Sub Bottom Profiler, Sampling: Biology, Sampling: Geology, Sampling: Chemistry, Biological Field Study: Experiments (biological), Location-Elevation: Navigation, Environmental Data: CTD
Scientific Purpose/Goals: Collect data from 3 types of intraslope basins related to salt diapirism: Type I (Gyre Basin) = submarine canyon blocked by active diapirs; Type II (Orca Basin) = interdomal basin formed by upward moving diapirs leaving central area in near original depth; and Type III (Carancahua) = collapse basin caused by either extension of sediment or salt solution from top of diapir. The plan was to study in detail each type of basin using seismic reflection, core/sample gear, bottom camera, CTD, and water bottles.
