Description:
Abstract:
The Neuse River Estuary in North Carolina is a broad, V-shaped water body located on the southwestern end of Pamlico Sound. This estuary suffers from severe eutrophication for which several water quality models have recently been developed to aid in the management of nutrient loading to the estuary. In an effort to help constrain model estimates of the fraction of nutrients delivered by direct ground-water discharge, continuous resistivity profile (CRP) measurements were made during the spring of 2004 and 2005. CRP is used to measure electrical resistivity of sediments, a property that is sensitive to difference in salinity of submarine ground water. The 2004 and 2005 surveys used floating resistivity streamers of 100 m and 50 m respectively. The depth penetration of the streamers is approximately 20% of the streamer length which translates to approximately 20-25 m with the 100 m streamer and 12-14 m with the 50 m streamer. These data were processed using AGI's EarthImager 2D software. CRP data enables the mapping of the extent and depth of the fresher ground water within the estuary.
Purpose:
To provide high resolution bathymetry TIFF image for the Pamlico Sound area in North Carolina.

A thorough metadata file generalized for the generic bathymetric digital elevation model is available from the website. What follows is the text supplied on the NOAA website regarding these data: The high resolution bathymetric data are gridded to 30m cells defined on a UTM projection where the locations of the value for each cell are at coordinates in UTM meter units evenly divisible by 30. The origin of these units is 500,000 meters west of the central meridian for the UTM projection and the equator. It should be noted that these UTM grids do NOT align with geographic parallels and meridians which define the extents of these DEM data sets. These 30m gridded data are equivalently referred to as UTM, 7.5 minute, or 30m data. In this context these terms are interchangeable.

Null values (encoded -32767 within the DEMs) are used to represent all locations either above (outside) the local high water datum (the shoreline as defined by the National Ocean Service) or outside the extents of the estuary as delineated by the CAF.

Bathymetric elevations within these data sets are referenced to the local tidal datum which typically is Mean Lowest Low Water (MLLW) averaged over a 19 year tidal epoch. Elevations above this datum (between the datum and the shoreline) have positive values (meters to centimeter resolution) while those below are negative. Note that this datum is different from that used by USGS for land elevation data that it distributes in DEM form which are referenced to Mean Sea Level (MSL).

Process_Step:
Process_Description:
A hillshade relief grid was created from the estuary bathymetry grid using ArcGIS 9.0. The parameters were left at the default values, except vertical exaggeration was set to 25. Both the bathymetry grid and the resulting hillshade grid were UTM, Zone18, NAD83.

Source_Produced_Citation_Abbreviation: est_hsh_v25
Process_Step:
Process_Description:
Both the bathymetry grid and the hillshade grid were loaded into ArcView 3.3. After creating the desired color table for the bathymetry grid, the two grids were combined using the ArcView 3.3 extension "grid-to-image converter tool" (downloaded from www.esri.com). This resulted in a color shaded-relief TIFF image and the corresponding world file.
