Each cable was surveyed post burial. The data was aquired using WROV mounted R2 Sonic 2024 Multibeam Echosounder and the cable was followed, where buried, with an Innovatum Smartrak pipetracker system. Soundings were measured using the MBES and IPS instruments. Tidal reductions were calculated using GNSS height and vessel draft, then corrected to LAT using VORF model. Data is presesnted in georeferenced raster in tif format based on a 0.25m bin size.

Soundings were cleaned, corrected for motion, sound velocity, depths were adjusted to LAT using GNSS height and VORF model. Soundings were gridded at 0.25 m cell size using a mean estimator. Output exported as georeferenced raster in .tif format.
