The current phase of this cooperative research program is directed toward analyzing how bathymetric relief relates to the distribution of sedimentary environments and benthic communities. As part of this program, digital terrain models (DTMs) from bathymetry collected as part of NOAA's hydrographic charting activities are converted into ESRI raster grids and imagery, verified with bottom sampling and photography, and used to produce interpretations of seabed geology and hydrodynamic processes. Although each of the 7 continuous-coverage, completed surveys individually provides important benthic environmental information, many applications require a geographically broader perspective. For example, the usefulness of individual surveys is limited for the planning and construction of cross-Sound infrastructure, such as cables and pipelines, or for the testing of regional circulation models. To address this need, we integrated the 7 contiguous multibeam bathymetric DTMs into one dataset that covers much of Block Island Sound. The new dataset is adjusted to mean lower low water, is provided in UTM Zone 19 NAD83 and geographic WGS84 projections, and is gridded to 4-m resolution. This resolution is adequate for seafloor-feature and process interpretation, but small enough to be queried and manipulated with standard GIS programs and to allow for future growth. Natural features visible in the grid include boulder lag deposits of submerged moraines, sand-wave fields, and scour depressions that reflect the strength of the oscillating tidal currents. Bedform asymmetry allows interpretations of net sediment transport. Together the merged data reveal a larger, more continuous perspective of bathymetric topography than previously available, providing a fundamental framework for research and resource management activities off this portion of the Rhode Island coast. Purpose: To release a 4-m color shaded-relief GeoTIFF of the combined multibeam bathymetry generated from NOAA surveys H12009, H12010, H12011, H12015, H12033, H12137, and H12139 offshore in Block Island Sound in geographic coordinates.

Completeness_Report: All collected data were processed and used to produce this dataset. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal position of the launches acquiring multibeam bathymetry were determined using GPS corrected by U.S. Coast Guard differential GPS beacon stations at Moriches, NY and Acushnet, MA. The final CARIS combined base surfaces for the MBES data were produced at a 2-m cell size. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Attitude of the launches (e.g. pitch, roll, and heave) acquiring multibeam bathymetry were monitored by an Applanix TSS POS/MV 320 Version 3 GPS aided navigation system. Verified water levels are based on National Water Level Observation Network (NWLON) stations 8461490, New London, CT; 8452660, Newport, RI; and 8510560, Montauk, NY. The vertical resolution of the multibeam data is approximately 0.5% of the water depth. Although there are no depth attributes associated with the GeoTIFF image, pixel values convey RGB values of individual cells. Warmer colors (e.g. red) are shallower depths; cooler colors are deeper.

Process_Step: Process_Description: The 63-m NOAA Ship Thomas Jefferson and two 8.5-m aluminum Jensen launches (3101 and 3102) deployed from the ship acquired multibeam echosounder (MBES) data for 7 hydrographic surveys in Block Island Sound over an approximately 633.6-square kilometer area between May and October 2009. Registry numbers for the completed surveys include: H12009, H12010, H12011, H12015, H12033, H12137, and H12139. The MBES data were collected with a hull-mounted RESON SeaBat 455-kHz 8125 shallow-water system aboard launch 3101 and RESON single frequency (400-kHz) 7125 systems aboard launch 3102 and the NOAA Ship Thomas Jefferson. Original vertical resolution of the MBES data was 0.5 m for water depths less than 20 m and 1 m for the deeper parts of the survey area. The bathymetric datasets were acquired and digitally logged with HYPACK Hysweep, and processed by NOAA using CARIS Hydrographic Image Processing System (HIPS) software for quality control, to incorporate sound velocity and tidal corrections, and to produce the combined bathymetry adjusted for statistical error (BASE) surfaces. Horizontal positioning was by differential global positioning systems (DGPS); HYPACK 2009 was used for acquisition line navigation. Sound-velocity corrections were derived with frequent conductivity-temperature-depth profiles. A Brooke Ocean Technology Moving Vessel Profiler (MVP) with an Applied Microsystems Smart Sound Velocity and Pressure (SV&P) sensor was used to collect sound speed profile data from the ship. Manually deployed Seabird Electronics SBE-19+ CTD units were used to collect sound speed profile data from the launches. Tidal zone corrections were calculated from data acquired by the National Water Level Observation Network stations at New London, Connecticut (8461490); Newport, Rhode Island (8452660); and Montauk, New York (8510560). The vertical datum is mean lower low water; X and Y units are meters, UTM Zone 19, NAD83. Detailed descriptions of the MBES acquisition and processing by NOAA can be found in the Descriptive Reports and in the Data Acquisition and Processing Report.
