Description:
Abstract:
This data release contains coastal wetland synthesis products for Massachusetts, developed in collaboration with the Massachusetts Office of Coastal Zone Management. Metrics for resiliency, including unvegetated to vegetated ratio (UVVR), marsh elevation, and tidal range are calculated for smaller units delineated from a digital elevation model, providing the spatial variability of physical factors that influence wetland health. The U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands with the intent of providing Federal, State, and local managers with tools to estimate the vulnerability and ecosystem service potential of these wetlands. 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.
Purpose:
The purpose of this shapefile is to calculate mean tidal range in each marsh unit. 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. Biomass production is positively correlated with mean tidal range in salt marshes along the Atlantic coast of the United States. 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 of mean tidal range (i.e., mean range of tides, MN) in Massachusetts salt marsh complexes. Mean tidal range, MN, was based on the calculated difference in height between mean high water (MHW) and mean low water (MLW) using the VDatum (v.4.1.2) database (http://vdatum.noaa.gov/).

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Marsh units and water and land boundaries inherit their horizontal accuracy from the accuracy of the source data, the conceptual marsh units, and their vertical accuracy from the elevation datasets (USGS CoNED, USGS 1-meter DEM, and USGS NED). Mean tidal range is calculated from the VDatum database, then interpolated on a raster surface and averaged at each marsh unit. If a marsh unit does not overlap with any raster cell center, it is assigned the value of the raster cell with the largest overlap.
Logical_Consistency_Report:
Polygons do not overlap and mean tidal range is positive. During processing of conceptual marsh units, small polygons (less than 9 m^2) were assumed to be marginal and were assigned the classification from the surrounding majority value. In one area (around marsh unit 6125), there are marsh units that have straight lines for boundaries; this is due to larger areas of hydro-flattened bathymetry/elevation values that do not allow the basin analysis to identify ridge lines between basins. These marsh units have a flag that shows that the hydro-flattened area of the marsh unit is greater than 25 percent of the marsh unit area.
Completeness_Report:
The results are specific to the marsh polygons as defined within the boundaries of Massachusetts salt marshes. Sliver polygons of open salt water along the marsh edges may also be included in some instances as a result of geoprocessing. In some marsh units there are small sliver gaps due to coupling of artifacts of the NWI (e.g., NWI polygons for ditches that are classified as riverine) and geoprocessing when the marsh polygons were closer than 10 meters at a specific section that is followed by a wider distance (e.g., access roads, fringing forests, etc.). The effect of these slivers on the calculations is negligible. For example, in marsh units 5958 and 5965 the sliver gaps are a result of the geoprocessing steps that remove riverine polygons. Other examples include marsh units 165, 308, 648, 3441, 5613. A detailed on-the-ground analysis of a single site may result in a different interpretation of the wetland and marsh unit boundaries. Occasionally, marsh units are retained in this dataset even though the imagery displayed extreme change (e.g., partially or completely converted to water) from the NWI wetland delineation.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Horizontal accuracy for the polygon boundaries is inherited from the source layer, the conceptual marsh units, and is considered to be +/- 6 meters. The point cloud used for calculating tidal range with VDatum had a 0.0005 arc degree (~50-meter) resolution that was interpolated over a 0.0001 arc degree raster prior to clipping and calculating the mean value for each marsh unit.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The maximum cumulative uncertainty for the Maine, New Hampshire, Massachusetts - Gulf of Maine operational VDatum region is given as 0.134 meters. See Estimation of Vertical Uncertainties in VDatum for more information (https://vdatum.noaa.gov/docs/est_uncertainties.html).

Process_Step:
Process_Description:
This process step and all subsequent process steps were performed by the same person, Kate Ackerman, in ArcMap (ver. 10.7.1) using tools from ArcToolbox, unless otherwise stated. For complex operations, names of specific tools used are given in CAPITAL letters (any critical parameters used are given in parentheses, separated by a semicolon, immediately after the tool name). The input and output file names are provided in [square brackets] when necessary. Units for length and area calculations are meters (m) and square meters (m^2) unless otherwise stated.
Establish marsh unit boundaries. Dissolve the vegetated and unvegetated classes in each marsh unit to have only one class for each marsh unit. DISSOLVE(Input features=[CMU_MA.shp]; Dissolve field=FID_CMU; Statistics field=ATOT_M2 and FLG, with Statistics type= First). PROJECT(Input coordinate system=WGS 1984 Web Mercator Auxiliary Sphere; Output coordinate system=GCS_NAD_1983_2011) the feature dataset to obtain dissolved marsh units [mu_diss.shp].
The FLG field identifies anomalous marsh units based on the absence of vegetation, the elevation, surface area, and tidal range extrapolation. The flags are calculated in their respective shapefile (i.e., elevation flags are calculated in the elevation shapefile). Set FLG to: (-1) no vegetated area in the marsh unit; (-10) marsh unit elevation higher than the 99.8 percentile; (-100) marsh unit elevation less than the 0.2 percentile; (-200) greater than 25 percent of the marsh unit elevation is hydro-flattened; (-1000) marsh unit surface area less than 900 m^2; (-10000) mean tidal range of marsh unit is extrapolated; and (0) no flag. Combination of negative values indicates a combination of flags; for example, -1001 indicates no vegetated area and area less than 900 m^2.

Process_Step:
Process_Description:
Calculate Mean Range of Tides (MN) using the VDatum (v.4.1.2) database covering this region. Mean range of tides (MN) = mean high water level (MHW)- mean low water level (MLW) in the VDatum database. Interpolate MN to the point dataset. a) Input point cloud file [Tidal_Points.txt] to VDatum. Set the HORIZONTAL INFORMATION (Reference Frame (NAD83 (2011)), Coordinate System (Geographic)) to be the same for the source and target. Set the VERTICAL INFORMATION (Source Reference Frame: MHW (meters); Target Reference Frame: MLW (meters)). Choose ASCII FILE CONVERSION (exclude NODATA points) and save output [MN.txt]. The resulting text file includes latitude, longitude and MN.

IDW(Output Cell Size=0.0001 degree; Power=2; Search Radius=Variable; Number of Points=12; Input barrier polyline features – if necessary) to obtain [MN_raster_idw.tif]. After running this tool, it may be apparent that input barrier polyline feature(s) need to be created to separate areas of unrelated tidal range data (e.g., where values from one body of water cross land to another body of water); in those cases, this tool was re-run with the input barrier polyline features specified. Input barrier polyline features were created on Cape Cod, Nantucket and adjacent to the Merrimack River.

Entity_and_Attribute_Overview:
In this dataset, tidal range for each conceptual salt marsh unit in Massachusetts salt marshes has been calculated based on a 0.0005 arc degrees interpolated VDatum dataset. 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 area and tidal range values is assumed to be 1 meter and 0.01 meter, respectively.
