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 over the previously determined conceptual salt marsh unit polygons with this dataset.

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: Polygons do not overlap.
Completeness_Report:

The boundaries of this dataset were created by expanding the outline boundaries of polygons created with a 250 meter exterior 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. Any polygons with an area smaller than 50 square meters were omitted in the source dataset.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Horizontal accuracy for the polygon boundaries is inherited from the source layer, conceptual marsh units, and considered to be greater than 3 meters. The point cloud used for calculating tidal range with VDatum had ~300-meter resolution that was interpolated over a 3-meter raster prior to clipping and calculating the mean value for each mash unit. The overall horizontal positional accuracy is expected to be on the order of 3 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. See Estimation of Vertical Uncertainties in VDatum for more information (https://vdatum.noaa.gov/docs/est_uncertainties.html#estTidalDatum).

Process_Description:

Calculate Mean Range of Tides with VDatum (v3.5) http://vdatum.noaa.gov/.
a) Create a point cloud with 10 arc sec (~300 meters) spacing to calculate the mean range of tides (MN). This comma separated file includes columns for latitude, longitude and height (set to zero).
b) Input point cloud file to VDatum. Set COORDINATE SYSTEM (Geographic), HORIZONTAL DATUM (NAD83), VERTICAL UNIT (meters), HEIGHT/SOUNDING (height) options same for the input and output. Set VERTICAL DATUM for input and output MHW and MLW, respectively. The choice of horizontal datum is to facilitate conversion between tidal datums, and it has no effect on the input/output dataset because it is identical for both of them.
c) After running VDatum, remove missing data (-99999) from the output dataset.

Overview_Description:

Entity_and_Attribute_Overview:

In this dataset, mean tidal range (i.e. Mean Range of Tides, MN between MHW and MLW) as calculated by the VDatum software is averaged over the previously defined conceptual marsh units in the salt marsh complex EBFNWR. 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.
