The Dolphin Deep Development Geohazard Project consisted of three phases: (1) Data Compilation (including re-processing existing bathymetry and seismic reflection data); (2) Analysis and Interpretation of Existing Data; (3) Data Collection (HR and UHR seismic reflection, HR bathymetry and side-scan sonar data); (4) Analysis and Interpretation of new data; (5) Pipeline Route Optimization.
