Survey method

All four views show the same 1,152 × 816 m footprint, using the delivered survey coordinates. MBES uses numerical 1 m depth grids from Pre-construction and Post-construction, with a shared palette and lighting. Unsurveyed cells remain empty.

Both side-scan views use actual georeferenced survey mosaics: 1 m in Pre-construction and 0.5 m in Post-construction. Amber and display contrast are applied to reveal texture. Sonar brightness is not calibrated between surveys and is not a measurement of change.

The cross-cut connects the profile at the structure to its location and both surveys.
