Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of sea-floor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters of coastal Massachusetts, primarily in water depths of 3-30 meters deep. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html). The data collected in the study area located in Vineyard Sound Massachusetts includes high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection). The data were collected during three separate surveys conducted between 2009 and 2011and cover approximately 340 square kilometers of the inner continental shelf. More information about the individual USGS surveys conducted as part of the Vineyard Sound project can be found on the Woods Hole Coastal and Marine Science Center Field Activity webpage: 2009-002-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2009-002-FA 2010-004-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2010-004-FA 2011-004-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2011-004-FA Purpose: The purpose of this polyline shapefile is to display generalized depth contours at 5 meter intervals derived from bathymetry collected by the USGS during surveys 2009-002-FA, 2010-004-FA, and 2011-004-FA in Vineyard Sound Massachusetts.

Logical_Consistency_Report: Bathymetric contours were generalized, simplified, and smoothed to improve the cartographic display of contours. As a result of this process small areas with depth values of less than 5 meters were omitted though the generalization, smoothing and simplification process. Generalized contours were produced in some areas of "no data" (in the input grid)as a result of the generalization process. Completeness_Report: Small depth contours less than 500 meters in length were removed to improve cartographic display. Lineage: Process_Step: Process_Description: Step 1. Generalize the input depth raster: The input raster (vs_bath5m_v2) was smoothed using the ArcGIS 9.3 geoprocessing step described below: Smooth input grid using a 5x5 mean filter with the Block Statistics Tool in ArcToolbox (ver. 9.3) Input raster = vs_bath5m_v2, Output raster = BlockSt5m_v2, Neighborhood= Rectangle, Neighborhood Settings = 5 x 5, cell Statistics type = Mean, Ignore NoData in calculations=selected.

Calculate generalized depth contours from smoothed depth grid using ArcToolbox (ver. 9.3). Both input depth grid and output feature class are in the UTM Zone 19, WGS 84 Coordinate System. Part 1) Create 5 meter contours using Contour tool: Contour Input raster = BlockSt5m_v2, Output polyline features = VS5mCntr_50m_v2 Contour Interval = 5, Base Contour = 5, Z Factor = 1, Raster Analysis cell size = 50m, Snap Raster = vs_bathv2_5m. Part 2) Simplify Line: Input Features = VS5mCntr_50m_v2, Output Feature Class = VS5mCntr_50m_Simple100_v2, Simplification Algorithm = Bend_Simplify, Reference Baseline = 100, Meters, Check for topological errors and Resolve topological errors options were both selected. Part 3) Smooth Line: Input Features = VS5mCntr_50m_Simple100_v2, Output Feature Class = VS5mCntr_50_SimpleSmooth_v2, Smoothing Algorithm = Bezier_Interpolation, Handling Topological Errors = was not selected.

Remove all contours less than 500 meters in length. Add new field "Length_m" of type "double to the attribute table using the context menu in ArcCatalog (ver 9.3). In ArcMap (ver 9.3) select new "Length_m" attribute and populate attribute using the "calculate geometry" context menu. All contours with length of 500 meters or greater were then selected using the "select by attributes" feature in ArcMap (ver. 9.3). The shapefile with the selected features was exported to a new shapefile using the context menu within ArcMap (ver. 9.3) table of contents with the following parameters "Export Data" Export= Selected features, Use the same coordinate system as: the data frame (set to GCS_WGS_1984), output shapefile= VS_5mCntr_V2.shp. Remove the following three attributes using the "Delete Field in ArcCatalog (ver 9.3) ID, MaxSimpTol, MinSimpTol. They were produced as part of the generalization process and are not required for further analysis.
