The USGS, in cooperation with NOAA and the Connecticut DEP, is producing detailed maps of the seafloor in Long Island Sound. 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 (primarily of 2-m resolution), verified with bottom sampling and photography, and used to produce interpretations of seabed geology and hydrodynamic processes. Although each of the 18 completed surveys, ranging in area from 12 to 293 square kilometers, 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 12 multibeam and 2 LIDAR (Light Detection and Ranging) contiguous bathymetric DTMs into one dataset that covers much of eastern Long Island Sound. The new dataset is adjusted to mean lower low water, is provided in UTM Zone 18 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 exposed bedrock outcrops, 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. Anthropogenic artifacts visible in the bathymetric data include a dredged channel, shipwrecks, dredge spoils, mooring anchors, prop-scour depressions, buried cables, and bridge footings. 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 in this major east-coast estuary.
To release a color shaded-relief GeoTIFF of the 4-m combined multibeam and LIDAR bathymetry generated from NOAA surveys H11224, H11225, H11250, H11251, H11252, H11361, H11441, H11442, H11445, H11446, H11997, H11999, H12012, and H12013 offshore in eastern Long Island Sound and westernmost Block Island Sound in geographic, WGS84 coordinates.

No additional checks for consistency were performed on this data.
All collected data were processed and used to produce this dataset.
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, Sandy Hook, NJ, and Acushnet, MA. Real-time positioning during LIDAR acquisition was obtained by an Ashtech GG24 GPS receiver combined with Thales GeoSolutions Wide Area DGPS. Original horizontal resolution of the MBES data was 0.5 - 2 m; original cell size of the gridded LIDAR data was primarily 4 m. The final CARIS combined base surfaces for the MBES data were produced at a 2-m cell size; final cell size of the gridded LIDAR data was 4 m.
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. Real-time positioning during LIDAR acquisition was obtained by an Ashtech GG24 GPS receiver combined with Thales GeoSolutions Wide Area DGPS. Ashtech Z12 GPS receivers, provided as part of the Airborne System and Ground Systems, also logged GPS data on the aircraft and at a locally established base station to provide post processed KGPS position solutions. Received infrared laser energy, supplemented by an Altitude Heading Reference System (AHRS) inertial height reference and kinematic GPS, determined the height of the aircraft. Verified water levels are based on NWLON stations 8461490, New London, CT and 8465705, New Haven, CT. 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.

The NOAA Ship Thomas Jefferson, and two 8.5-m aluminum Jensen launches deployed from the ship, were used to acquire the multibeam echosounder (MBES) bathymetric data between October 2003 and May 2009 for surveys H11250, H11251, H11252, H11361, H11441, H11442 H11445, H11446, H11997, H11999, H12012, and H12013. Aboard the launches, the 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. Aboard the Thomas Jefferson, MBES data for surveys H11250, H11252, and H11361 were collected with a SIMRAD EM1002 system; later surveys were collected with a RESON 7125 system. Original horizontal resolution of the MBES data was 0.5 to 2 m, depending on survey and water depth; 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. Navigation was by TSS POS/MV 320 differential GPS-assisted inertial navigation systems; the differential GPS beacons used were from Moriches, New York, and Sandy Hook, New Jersey. 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 four to six hours of MBES acquisition. Tidal zone corrections were calculated from data acquired from National Water Level Observation stations at New London, Connecticut, New Haven, Connecticut, and Montauk, New York. Vertical datum is mean lower low water. Individuals interested in detail descriptions of the MBES acquisition and processing should consult the descriptive reports. Eleven reconnaissance cruises were conducted aboard a leased lobster boat to monitor water clarity prior to commencement of airborne LIDAR operations of surveys H11224 and H11225. These cruises, which utilized Secchi disks to determine water clarity, were conducted between the Connecticut River and Fishers Island during May 9, 2003 and January 11, 2004, when water clarity was deemed adequate. The LIDAR (light detection and ranging) data were acquired by Tenix LADS, Inc. during January 25 - March 3, 2004 with a LADS Mk II system. Airborne survey operations were conducted aboard a Dash 8-202 series aircraft with a Nd:YAG laser at heights between 1,200 and 2,200 feet, at ground speeds between 140 and 210 knots, and at 4x4 and 3x3-m laser-spot spacings. Green laser pulses were scanned beneath the aircraft in a rectilinear pattern. The returned green-laser energy reflected from the sea surface and seafloor were captured and digitally recorded. Received infrared laser energy, supplemented by an Altitude Heading Reference System (AHRS) inertial height reference and kinematic GPS, determined the height of the aircraft. Real-time positioning was provided by WADGPS (wide area differential global positioning system). Acquired data were processed with CARIS HIPS. Individuals interested in detail descriptions of the MBES and LIDAR acquisition and processing should consult the descriptive reports. Vertical datum is mean lower low water; X and Y units are meters; UTM Zone 18, NAD83.

The UTM projected GeoTIFF was imported into ArcGIS v9.3 and reprojected using the data management tool Project Raster (ArcToolbox, Data Management Tools, Projections and Transformations) from UTM Zone 18N, NAD 83 to Geographic, WGS84. The options specified in the Project Raster tool were:
1. Input coordinate system: NAD_1983_UTM_Zone_18N
2. Output coordinate system: GCS_WGS_1984
3. Geographic transformation method: NAD_1983_WGS_1984_5
4. Resampling technique: BILINEAR
5. Output cell size: 0.000043 (decimal degrees, default as calculated by ArcMap for a 4 meter cell size)
The geographic transformation selected is the most accurate one provided by ESRI as it ties in WGS84 with ITRF96, thus reflecting the earth centered offset (x-y-z) between WGS84 and NAD83 (from the ESRI Knowledge Base Document Number 24159).

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.). Reordered the links in the identification section so a landing page link is first. Added the source citation abbreviation and used the title for the value. Attempted to modify http to https where appropriate. 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.

A color-encoded hill-shaded GeoTIFF of the combined bathymetry data from NOAA surveys H11224, H11225, H11250, H11251, H11252, H11361, H11441, H11442, H11445, H11446, H11997, H11999, H12012, and H12013 offshore in eastern Long Island Sound and westernmost Block Island Sound in geographic, WGS84 coordinates. There are no attributes associated with the GeoTIFF image. Pixel values convey RGB values of individual cells. Warmer colors (e.g. red) are shallower depths; cooler colors (e.g. blues) are deeper.
