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 2001 for charting applications as part of NOAA project OPR-B340-RU, survey H11044 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 5-m interpolated and regridded bathymetry generated from NOAA survey H11044 in Long Island Sound off Milford, Connecticut.

Areas of no data exist between many of the ship's tracks. 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 1.5 m; vertical datum is mean lower low water.

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 GMT (the Generic Mapping Tools) was used to create a 3-m interpolated grid of the bathymetry. Interpolation was achieved during GMT processing by running the data through a block median filter and using a surface generating algorithm with a tension of 0.5. Other parameters were set at default. The grid was projected into Universal Transverse Mercator, Zone 18N.

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.). Attempted to modify http to https where appropriate. Added the place keyword thesaurus for the place keywords. Added ISO 19115 Topic Category keywords. Added a distributor. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. Added the online link to the zipped data file in the distribution section. 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.
