Description:
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Bathymetry and sidescan-sonar imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities in Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During October 2008 NOAA completed hydrographic survey H11251 offshore of Rocky Point, New York and during November 2009, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Interpretive data layers were derived from the multibeam echo-sounder and sidescan-sonar data and the ground-truth data used to verify them. For more information on the ground-truth survey see <http://quashnet.er.usgs.gov/data/2009/09059/>
Purpose:
To release a 2-m grid of the multibeam bathymetry generated during NOAA survey H11251 offshore of Rocky Point, New York in UTM Zone 18, NAD83.

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 2 m for the deeper areas; the final CARIS combined base surface for the MBES data were produced at a 2-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 resolution of the original bathymetry data is approximately 0.5% of the water depth.

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 H11251 during October 2008 offshore of Rocky Point, New York. The launch MBES data were collected with hull-mounted RESON SeaBat 240-kHz 8101 and 455-kHz 8125 shallow-water systems. These systems measure two-way sound travel time across a 150-degree swath and 120-degree swath, respectively. The SeaBat 8101 has 101 beams at a 1.5-degree beam spacing. The SeaBat 8125 has 240 beams with a cross-track beam width of 0.5 degrees at nadir. The ship's MBES data were collected with a RESON 7125 system 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 2 m for the deeper areas. Vertical resolution of the MBES data is about 0.5% of the water depth. The bathymetric data were acquired in XTF (extended Triton data format) 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 MAX 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 data acquired from National Water Level Observation stations at New London and New Haven, Connecticut. 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 2-m resolution and saved as a CARIS HIPS database in UTM Zone 18, NAD83.

Process_Description:
Converted the Fieldsheet file (h11251_ahb_2m_combined) from the NOAA CARIS database to a DTM file using IVS DMagic v6.7. The floating point format for each sounding depth point is preserved during data import. These fieldsheets were imported into DMagic as "gridded data", therefore re-gridding of data did not occur during the import process and thus preserved the original resolutions of the CARIS fieldsheet.
