Description

In 2002 and 2003, hydrographic survey data were collected using Reson 8101 multibeam echo sounders outfit to 9.8m survey launches. Bathymetry data were cleaned of anomalies using Caris HIPS software, creating BASE (Bathymetry Associated with Statistical Error)surfaces for each of three survey blocks with the CUBE (Combined Uncertainty Bathymetric Estimator) method (Calder and Mayer 2003).Accepted XYZ values from the CUBE surface were ultimately converted to ESRI Arc ascii grid format.
