To release a 1-m grid of the multibeam bathymetry generated during NOAA survey H12007 in the vicinity of Cross Rip Channel in Nantucket Sound, offshore southeastern Massachusetts in UTM Zone 19, NAD83.
National Ocean Survey, National Oceanic and Atmospheric Adminis, Unpublished Material, H12007 bathymetry.
Vertical offsets are present in the data, but none exceed the permissible error limits. The sources of these offsets include 1) change and acceleration of current flow in the narrow channel that changed the draft of the survey vessel, 2) shifting of sand waves due to strong currents, 3) a consistent 15-20 cm positive bias in the data from launch 3102, and 4) a faulty RESON 7125 multibeam receiver on the Thomas Jefferson.

Horizontal position of the ship and launches acquiring multibeam bathymetry were determined by differential GPS. Real-time original horizontal resolution of the MBES data was 0.5 m for depths less than 20 m and 1 m for the deeper areas; the final CARIS combined base surface for the MBES data were produced at a 1-m cell size.
Attitude of the vessels (e.g. pitch, roll, and heave) acquiring multibeam bathymetry were monitored by Applanix TSS POS/MV 320 Version 3 GPS aided navigation systems. The vertical accuracy of the original bathymetry data is approximately 0.5% of the water depth.
All collected data were processed and used to produce this dataset. Although all data were used, we recognize that vertical offsets are present in the data. None of the offsets exceed the permissible error limits. The sources of these offsets include 1) change and acceleration of current flow in the narrow channel that changed the draft of the survey vessel, 2) shifting of sand waves due to strong currents, 3) a consistent 15-20 cm positive bias in the data from launch 3102, and 4) a faulty RESON 7125 multibeam receiver on the Thomas Jefferson.
No additional checks for consistency were performed on this data.
