The survey was conducted over the course of two weeks – March 26th – April 9th, 2019. The data meet the requirements for IHO Special Order standards.

All MBES data acquisition was undertaken at a typical vessel speed of 8 knots, with a swath width typically 2-3 times water depth or ~ 15-20 km. Survey lines were spaced between 6-7 km to ensure 100% overlap over areas of interest. All raw bathymetry data were processed in QPS Qimera and gridded to 75 m using CUBE algorithms. CUBE algorithms use the surrounding depth information and advanced statistical practices to determine the best estimate of depth while simultaneously calculating the uncertainty of those estimates. The total propagated uncertainty (TPU) was calculated for each dataset.
