- Abstract:
- The U.S. Geological Survey, in cooperation with the
National Oceanic and Atmospheric Administration and the Connecticut
Department of Environmental Protection, has produced detailed geologic
maps of the sea floor in Long Island Sound, a major East Coast estuary
surrounded by the most densely populated region of the United States.
These studies have built upon cooperative research with the State of
Connecticut that was initiated in 1982. The current phase of this
research program is directed toward studies of sea-floor sediment
distribution, processes that control sediment distribution, nearshore
environmental concerns, and the relation of benthic community
structures to the sea-floor geology.
The bathymetry data in this data set were collected during 2002 for
charting applications as part of NOAA project OPR-B340-RU, survey
H11043 aboard the NOAA Ship RUDE. The RUDE, which supports NOAA's
east-coast nautical charting mission, is outfitted to acquire
single-beam bathymetry with an Odom Echotrac DF-3200 duel frequency
echosounder and shallow water multibeam bathymetry with a Reson 8125
system. The Reson multibeam system operates at 455 KHz with a 120
degree across track swath and 240 beams along its swath.
- Purpose:
- To release the 2-m interpolated, regridded, and
hill-shaded bathymetry generated from NOAA survey H11043 in Long Island
Sound off Branford, Connecticut.

- Process_Step:
-
- Process_Description:
- The multibeam data for this survey was acquired in
XTF (extended Triton data format) and recorded digitally through an
ISIS data acquisition system. Once digitally recorded, the XTF data
were processed using CARIS HIPS/SIPS software to quality control the
data and to incorporate sound velocity and tidal corrections. Data were
gridded to 1 m; vertical datum is mean lower low water.

- Process_Step:
-
- Process_Description:
- The original multibeam data sets, which are in ASCII
comma-delimited text, do not entirely cover the sea floor because line
spacing during acquisition was such that areas of no data often are
present between the ship's tracks. Therefore, further processing was
conducted at the USGS's Woods Hole Science Center to provide
bathymetric datasets with more continuous coverage. First, all
non-standardized records were assumed to be bad records and were
removed. Subsequently, the PROJ.4 cartographic projections library was
used to project the data, the SwathEd software produced by the Ocean
Mapping Group at the University of New Brunswick was used to create the
grids from the actual sounding data, and the GRASS (Geographic
Resources Analysis System) was used to create interpolated grids of the
bathymetry for each survey. The grid was projected into Universal
Transverse Mercator, Zone 18N.
