Description:Since the 1930s, most of New Jersey's intracoastal waters have not been surveyed to NOAA's Coast Survey hydrographic standards. As a result, the bathymetry that is used to compile the large-scale nautical charts (1:40,000) of New Jersey's back bays is outdated. The main reason is lack of resources that are required to conduct IHO hydrographic surveys in shallow waters. As part of the Superstorm Sandy relief efforts, a novel approach is applied to update these charts. Bathymetry data collected by other federal and state agencies is being used to provide a current depiction of the bathymetry and update the metadata associated with surveys (IHO S57 attributes). All data sets that are available over a given area are ranked based on the survey technology and the service provider. In this project, the datasets were classified into three main groups based on CATZOC classes. Finally, compiled datasets were used to generate a suite of products that include a coverage map of the hydrographic characteristics, bathymetry (smooth sheet soundings and depth curves) and supplementary documentation. This report outlines the different datasets used in the project and the Coastal Composite Bathymetry (CCB) procedure. In addition to chart update, the CCB procedure is also used to evaluate the adequacy of the data used in the chart. [doi.org/10.7289/V5/TR-NOS-CS-37 (https://doi.org/10.7289/V5/TR-NOS-CS-37)]
