Forsythe National Wildlife Refuge, New Jersey: U.S. Geological Survey data release, https://doi.org/10.5066/F7CF9N7X Online_Linkage: https://doi.org/10.5066/F7CF9N7X Description: Abstract: Biomass production is positively correlated with mean tidal range in salt marshes along the Atlantic coast of the United States of America. Recent studies support the idea that enhanced stability of the marshes can be attributed to increased vegetative growth due to increased tidal range. This dataset displays the spatial variation mean tidal range (i.e. Mean Range of Tides, MN) in the Edwin B. Forsythe National Wildlife Refuge (EBFNWR), which spans over Great Bay, Little Egg Harbor, and Barnegat Bay in New Jersey, USA. MN was based on the calculated difference in height between mean high water (MHW) and mean low water (MLW) using the VDatum (v3.5) software (http://vdatum.noaa.gov/). The input elevation was set to zero in VDatum to calculate the relative difference between the two datums. As part of the Hurricane Sandy Science Plan, the U.S. Geological Survey has started a Wetland Synthesis Project to expand National Assessment of Coastal Change Hazards and forecast products to coastal wetlands. The intent is to provide federal, state, and local managers with tools to estimate their vulnerability and ecosystem service potential. For this purpose, the response and resilience of coastal wetlands to physical factors need to be assessed in terms of the ensuing change to their vulnerability and ecosystem services. EBFNWR was selected as a pilot study area. Purpose: Analysis of mean tidal range is part of a comprehensive assessment to identify the factors and their weights in determining the vulnerability and resiliency of salt marshes. The results are summarized with a 30-meter resolution raster dataset in an area bounded by the EBFNWR salt marsh complex and a 250 meter buffer zone around it. The buffer area is created solely to provide extra margin for any prospective geoprocessing and should not be included in the final results.

Edition: version 3.5 Publication_Information: Publication_Place: Silver Spring, MD Publisher: NOAA Online_Linkage: http://vdatum.noaa.gov Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Water-land boundary and marsh unit boundaries inherit accuracy from the source data (see source information in lineage section), conceptual marsh units. Mean Range of Tides is calculated with the VDatum software then interpolated on a raster surface and averaged at each marsh unit. Logical_Consistency_Report: Mean tidal range values in the final raster file have similar value range and spatial distribution as the underlying VDatum calculations. Raster coverage agrees with the polygon boundaries used to define the geoprocessing extent. Completeness_Report: The boundaries of this dataset are defined by a 250 meter buffer around the source data, conceptual marsh units, which include: 1) Marsh Salt, 2) Wetland Scrub Shrub Salt, and 3) channels of Open Water Salt that are not wider than 50 meters. The buffer area is created solely to provide extra margin for any prospective geoprocessing and should not be included in the final results. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The point cloud used for calculating tidal range with VDatum had ~300-meter resolution that was interpolated over a ~30-meter raster over the 250 meter buffered marsh polygon. The overall horizontal positional accuracy is expected to be on the order of 30 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The maximum cumulative uncertainty for the New Jersey - Coastal embayments operational VDatum region is given as 9.2 centimeters.

Decimal values in the attribute table are a result of double precision calculations while significant digits are considered in defining the attribute measurement resolutions. Therefore, the smallest unit increment for calculated tidal range values can be assumed to be a practical value such as 0.01 m.
