Statement

All hydrographic surveys were executed aboard the DSSV Pressure Drop built in 1985 (68.28 m long by 13.11 m wide), fitted with a 1° x 2° Kongsberg EM 124 multibeam echosounder (MBES). 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.
