Horizontal positions of the ship acquiring multibeam bathymetry were determined with Trimble DSM212L DGPS receivers. Best expected position accuracy of the ship with the Trimble system less than 1 meter.
Attitude of the vessel (e.g. pitch, roll, and heave) acquiring multibeam bathymetry was monitored by an Applanix TSS POS/MV 320 Version 3 GPS aided navigation system. The vertical resolution of the original bathymetry data is approximately 0.5% of the water depth. Tidal zone corrections were calculated from the tide stations at New London and New Haven, Connecticut.
All collected data were processed and used to produce this dataset.
No additional checks for consistency were performed on this data.
