Forsythe National Wildlife Refuge (EBFNWR), which spans over Great Bay, Little Egg Harbor, and Barnegat Bay in New Jersey, USA is given in terms of mean elevation of conceptual marsh units defined by Defne and Ganju (2016). The elevation data is based on the 1-meter resampled 1/9 arc-second resolution USGS National Elevation Data. As part of the Hurricane Sandy Science Plan, the U.S. Geological Survey is expanding 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. References: Defne, Zafer, and Ganju, N.K. 2016, Conceptual salt marsh units for wetland synthesis: Edwin B. Forsythe National Wildlife Refuge, New Jersey: U.S. Geological Survey data release, https://doi.org/10.5066/F7QV3JPG. Purpose: Analysis of marsh elevation 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 (Defne and Ganju, 2016).

Forsythe National Wildlife Refuge, New Jersey Edition: 1.0 Geospatial_Data_Presentation_Form: Vector Digital Data Set (Polygon) Series_Information: Series_Name: data release Issue_Identification: DOI:10.5066/F7QV3JPG Publication_Information: Publication_Place: Reston, VA Publisher: U.S. Geological Survey Online_Linkage: https://doi.org/10.5066/F7QV3JPG Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Water and land boundary inherit from accuracy of source data EBFNWR. Marsh units elevation value accuracy depend on vertical and horizontal accuracy of the source, National Elevation Dataset (NED). Logical_Consistency_Report: Generally positive elevation means marsh unit is above sea level. There are 3 marsh units (FID_CMU= 499, 1312, 1320) which have been assigned zero elevation. These units, although classified to have regularly flooded, emergent wetland in the source dataset, are small land (less than 7000 m2), fragmented islands from mainland and receive zero elevation in NED. There are 11 marsh units (FID_CMU= 426, 427, 430, 444, 635, 1058, 1141, 1142, 1143, 1144, 1147, 1291) which have considerably high elevation (higher than 2 m) compared to the tidal range. Based on Google Maps aerial imagery these seem to be classified incorrectly as wetland in the source dataset and require ground truthing to clarify. Completeness_Report: The results are specific to the marsh polygons definition within the boundaries of the EBFNWR salt marsh complex (Defne and Ganju 2016). A detailed on-the-ground analysis of a single site may result in a different interpretation of the wetland and marsh unit boundaries. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal accuracy is inherited from NED 1/9 second (~3-meter) dataset. Although the analyses were performed at 1-meter resolution for smoother conformity with the clipping polygons, the resolution of the final product should be considered to be greater than 3 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical accuracy is inherited from NED 1/9 second (~3-meter) dataset. No additional accuracy assessment of the vertical positional information has been conducted.

Download date was 20160801. Process_Step: Process_Description: This process step and all subsequent process steps were performed by the same person, Zafer Defne, in ArcMap (ver. 10.5.1) using tools from ArcToolbox, unless otherwise stated. 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 (m2) unless otherwise stated. a) Prepare elevation dataset to be clipped to the boundaries polygon. MOSAIC TO NEW RASTER(Pixel type= 32 bit float; Mosaic operator=Mean; Cellsize=1 m) all of the USGS NED 1/9 second tiles to a new raster dataset with 1m resolution. Resolution is increased from 3 m to 1 m to have a finer representation of the polygon boundaries in the horizontal during this step. b) Calculate values for each marsh unit. DISSOLVE(Input features=[marshUnitsEBFp]; Output=[mu_disss.shp]; Dissolve field=FID_CMU) to dissolve the vegetated and unvegetated in each marsh unit into one feature. c) Clip the raster with the polygon features by using EXTRACT BY MASK to obtain [elev_idw_mu.tif]. d) ZONAL STATISTICS AS TABLE(Feature Zone Data=[marshUnitsEBFp]; zone field=FID_CMU; Value Raster=[elev_idw_mu.tif]; Output Table=mu; Statistics type=MEAN) e) ADD JOIN(Layer name=[marshUnitsEBFp]; Input join field=FID_CMU; Join Table=mu; Output join field=FID_CMU) to marsh units layer based on the "FID_CMU" field f) Export dataset as a shapefile [mu_elev.shp] and keep the 'mu_MEAN" and "mu_ATOT_M2" fields from the join operation. g) Calculate elevation of the vegetated areas only. SELECT BY ATTRIBUTES FROM [marshUnitsEBFp] where "CLASS"= 'vegetated'. SELECT BY ATTRIBUTES FROM [marshUnitsEBFp] where "CLASS"= 'vegetated'. Follow steps (c) to (f) using the selected features to export [veg_elev.shp]. h) JOIN FIELD(Input table=[mu_elev.shp]; Input join field=mu_FID_CMU; Join table=[veg_elev.shp]; Output join field=vg_FID_CMU; Join fields=vg_AVEG_M2,vg_ATOT_M2,vg_MEAN). Change the field names to VG_ELEV and MU_ELEV respectively for the fields with the mean elevation for the vegetated area only and mean elevation for the entire marsh unit. Name AVEG_M2 and ATOT_M2 for vegetated and total area, respectively, and export to a new shapefile [mu_elev_EBFNWRp.shp].
