The interpreted geophysical data reveals a flat, smooth seafloor with a homogeneous surficial sediment cover across the entire survey block, with no protruding obstacles (natural or artificial). The sediment surficial sediment of the deposit consists of a mixture of silty sand particles, typically with dense shell. This has been confirmed from grab and core samples collected from in and around the target dredge site SP-1. The geophysical information was collected using integrated multi beam echo sounder and side-scan sonar equipment.
