Bathymetry, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities off southern New England, shows the character and terrain of the seabed, and provides information on sediment transport and benthic habitat. During April-May 2009 NOAA completed hydrographic survey H12007 in the vicinity of Cross Rip Channel in Nantucket Sound off southern Cape Cod, Massachusetts and during June 2011 bottom photographs and surficial sediment data were acquired as part of ground-truth reconnaissance surveys of this area. Interpretations were derived from the multibeam echo-sounder data and the ground-truth data used to verify them. Purpose: To release a 1-m color GeoTIFF 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.

Completeness_Report: 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. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: 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. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: 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.

Source_Contribution: Original processed multibeam bathymetric data. Process_Step: Process_Description: Two 8.5-m aluminum Jensen launches and the NOAA Ship Thomas Jefferson were used to acquire the multibeam echosounder (MBES) bathymetric data for survey H12007 during April-May 2009 in central Nantucket Sound, offshore southeastern Massachusetts. The MBES data on launch 3101 were collected with a hull-mounted RESON SeaBat 455-kHz 8125 shallow-water system. This system measures two-way sound travel time across a 120-degree swath. The SeaBat 8125 has 240 beams with a cross-track beam width of 0.5 degrees at nadir. The MBES data were collected aboard the ship and launch 3102 with RESON 7125 systems which measured two-way sound travel time across a 140-degree swath. Original horizontal resolution of the MBES data was 0.5 m for depths less than 20 m and 1 m for the deeper areas. Vertical resolution of the MBES data is about 0.5% of the water depth. The bathymetric data were acquired and logged with HYPACK Hysweep and processed by NOAA using CARIS HIPS (Hydrographic Image Processing System) software for quality control, to incorporate sound velocity and tidal corrections, and to produce the continuous digital terrain model. All positioning and attitude were determined with Trimble DSM212L DGPS receivers and Applanix POS/MV Model 320 v.4 inertial navigation systems; HYPACK 2009 was used for acquisition line navigation. Sound velocity corrections were derived using frequent SEACAT CTD (conductivity-temperature-depth) profiles. Typically, a CTD cast was conducted every three to four hours of MBES acquisition. Tidal zone corrections were calculated from the tide station at Nantucket Island, Massachusetts. Vertical datum is mean lower low water. Individuals interested in detail descriptions of the MBES acquisition and processing should consult the descriptive reports. The data were gridded to 1-m resolution and saved as a CARIS HIPS/SIPS v6.1 SP2 database in UTM Zone 19, NAD83. 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.

This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
