Abstract:
During 2001 the NOAA Ship RUDE completed charting survey H11044 that covered a roughly 293 km2 area of the sea floor in north-central Long Island Sound, off Milford Connecticut. Although 100 percent coverage was achieved with sidescan sonar for charting purposes, only reconnaissance (spaced line) bathymetry was acquired with shallow-water multibeam and single-beam systems. Therefore, further processing was conducted at the USGS's Woods Hole Science Center to provide bathymetric datasets with more continuous coverage. This project produced grids and GeoTIFF imagery of the combined and interpolated shallow-water multibeam and single-beam bathymetry generated from the northern part of this data set. Anthropogenic wastes, toxic chemicals, and changes in land-use patterns resulting from residential, commercial, and recreational development have stressed the environment of the Sound, causing degradation and potential loss of benthic habitats. Detailed maps of the sea floor are needed to help evaluate the extent of adverse impacts and to help manage resources wisely in the future. Therefore, in a continuing effort to better understand Long Island Sound, we have interpolated and gridded shallow-water multibeam and single-beam bathymetric data within specific areas of special interest.
Purpose:
To release a 10-m interpolated grid of the shallow-water multibeam and single-beam bathymetry generated from the northern part of NOAA survey H11044 off Milford, Connecticut in UTM Zone 18, WGS84.

Original processed shallow-water multibeam and single-beam bathymetric data.
Process_Step:
Process_Description:
The multibeam data were acquired in XTF (extended Triton data format) and recorded digitally through an ISIS data acquisition system. A Reson SeaBat 9003 echosounder was used to acquire the shallow-water multibeam bathymetric data and an Odom Echotrac DF-3200 dual-frequency echosounder was used to acquire the single-beam bathymetry from the NOAA ship Rude. An Odom Echotrac DF-3200 dual-frequency echosounder hull-mounted on a 23' launch deployed from the NOAA ship Rude was used to acquire sounding data in the shallower areas. These data were processed using CARIS HIPS (Hydrographic Image Processing System) software for quality control, and to incorporate sound velocity and tidal corrections. 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 multibeam acquisition. Tidal zone corrections were calculated from data acquired at tidal gauges at Bridgeport and NewHaven, Connecticut, and at Kings Point, New York. The vertical resolution of the shallow-water multibeam data is approximately 0.5% of the water depth. The data were gridded to 1.5-m resolution and exported in text (.txt) format. Vertical datum is mean lower low water; X and Y units are decimal degrees.

A series of GMT v4.0 (the Generic Mapping Tools) are run during this process including Minmax to determine the data bounds and to help identify anomalous values [minmax UTM_H11044_1_5m.xyz]. An AWK script was run to filter the dataset and prepare it to be processed thru the GMT block median routine [awk '{if($3>0 && $3<22 $1>4555000) printf "%6.2f\t%7.2f\t%3.2f\n",$2,$1,$3*-1}' UTM_H11044_1_5m.xyz > sda_44.end]. Based on visual inspection of the removed data points (both their location and their elevation relation to the surrounding data points) the values above 22 were indeed anomalous.

GMT v4.0 programs were used to create a 10-m interpolated GMT grid of the bathymetry.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. 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 source information was incomplete and had to be modified to meet the standard. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. 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.
