Abstract:
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 the vulnerability of coastal wetlands to various factors and to evaluate their 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. Edwin B. Forsythe National Wildlife Refuge (EBFNWR), New Jersey, was selected as a pilot study area.
As part of this data synthesis effort, hydrodynamic and sediment transport modeling of Barnegat Bay Little Egg Harbor (BBLEH) has been used to create the following wetland data layers in Edwin B. Forsythe National Wildlife Refuge (EBFNWR), New Jersey: 1) Hydrodynamic residence time , 2) salinity change and 3) salinity exposure change in wetlands, and 4) sediment supply to wetlands. The residence time layer was based on the hydrodynamic and particle tracking modeling of the period 3/1/2012 to 5/1/2012 by Defne and Ganju (2015). For this data layer, the residence time map of estuarine water has been projected over the EBFNWR salt marshes. The rest of the layers were derived from the BBLEH hydrodynamic modeling for the Hurricane Sandy period that spans from 10/27/2012 to 11/04/2012 (Defne and Ganju, 2016a). The model estimated changes in salinity and sediment concentrations over the salt marshes caused by storm-induced coastal flooding. The results are summarized over the previously determined conceptual salt marsh unit polygons (Defne and Ganju, 2016b).
Purpose:
This polygon dataset facilitates quantifying vulnerability to contaminant hazards in the EBFNWR salt marsh complex by looking at the residence time of water within the complex. The results are summarized over the previously determined conceptual salt marsh unit polygons (Defne and Ganju, 2016b). Analysis of hydrodynamic residence time is part of a comprehensive assessment to identify the factors and their weights in determining the vulnerability and resiliency of salt marshes. Residence time is inferred from the residence time calculations in the Barnegat Bay - Little Egg Harbor (BBLEH) estuary based on the hydrodynamic and particle tracking modeling by Defne and Ganju (2015).

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Water-land boundary and marsh unit boundaries inherit from accuracy of source data, conceptual marsh units. Inferred residence time layer is calculated by resampling the bay water residence time at a higher horizontal resolution of 0.0003 degrees (~30 meters) prior to averaging over each marsh unit.
Logical_Consistency_Report:
By definition residence time cannot be a negative real number. Final values for each marsh unit were verified to be a positive real number.
Completeness_Report:
The polygon outlines for this dataset are defined by the conceptual marsh unit boundaries in the source dataset. That is the boundaries of the EBFNWR areas that include unvegetated and vegetated areas. A detailed on-the-ground analysis of a single site may result in a different interpretation of the wetland and marsh unit boundaries than established through this analysis.
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 residence time had variable horizontal resolution (~40 to ~300 meters) that was interpolated over a ~30-meter raster. The raster dataset was resampled at 3 meter resolution to enhance the conformity with the marsh unit boundaries prior to calculating zonal statistics.

Process_Step:
Process_Description:
This process step used ArcMap (ver. 10.3.1) using tools from ArcToolbox. Names of specific tools used are given in CAPITAL letters (any critical parameters used is given in parentheses, separated by a semicolon, immediately after the tool name). 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.
Defne and Ganju (2015) modeled estuarine circulation in BBLEH during March-May 2012 with a three-dimensional hydrodynamic model. The computational domain included a part of Great Bay to the south and Manasquan Inlet to the north in addition to Barnegat Bay and Little Egg Harbor. Neutrally buoyant, passive numerical particles that represent water parcels were released uniformly within the estuary and tracked until their first exit. The time elapsed for a particle to leave the estuary was assigned as a residence time to the initial release location of that particle to create a spatially varying residence time map. The residence time map of the estuary has been projected over the surrounding salt marshes with an inverse distance weighted interpolation method in the present study.

Process_Description:
Part of the EBFNWR salt marsh system to south of the Little Egg inlet is not covered by the particle modeling used to estimate the hydrodynamic residence time. Given the similar geospatial trend between the mean tidal range and the residence time, mean tidal range data layer is used calculate the residence time in the area without adequate coverage. The mean tidal range data from a region to the north of the Little Egg Inlet, which is approximately the same distance from the southern boundary of the marsh system is used for a regression analysis between the two parameters. First, marsh units that are inside and are outside of the BBLEH computational domain are determined.
a) Select features from [marshUnitsEBFp.shp] marsh polygons that are within the BBLEH computational domain and export as [mu_with_data.shp].
b) Invert selection and export polygons outside the computational domain as [mu_no_data.shp].

Overview_Description:
Entity_and_Attribute_Overview:
In this dataset, hydrodynamic residence time in BBLEH projected and averaged over each conceptual marsh unit in EBFNWR. A higher residence time indicates longer time required to exchange between the bay water surrounding the marsh unit and the open ocean. The inferred residence times in this dataset are not the actual residence times for water in the marsh units. Inferred residence time should be considered as a geospatially varying indicator of relative flushing time scales for the marsh units with respect to each other. 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 inferred residence time values can be assumed to be a practical value such as 0.01 days.
