title: Superstorm Sandy Coastal Dune Erosion Varies By Stabilizing Plant Species

description: This excel sheet is the raw data for Charbonneau et al. 2016 Invasive sedge stabilized dunes more than native grass during Hurricane Sandy. Journal of Applied Ecology. Data collected from Island Beach State Park, NJ, Barnegat Bay. <br>There are 6 sheets: <br>1) MainText_TensiometerData - ramet anchoring ability measured as uprooting force required using a 50 kg Pesola® tensiometer attached to a CK or AB caudex. For each individual, we recorded location within the stand, center or edge (within 30 cm from edge), height and width of the tallest leaf, and number of tillers per caudex. 2) MainText_InvasiveCKStands - lnvasive Carex kobomugi stand sizes pre-Sandy (Woo2008), during Sandy (est2012), and post-Sandy (POST). Stand ID is not unique, stands with the same number from different Times are the same stand or part of a fragmented stand. 3) MainText_ErosionbySpecies&Beach: data from main body of the research as described in the paper.4) MainText_ErosionAcrossPark(DCT) - DCT from north to south along the study area where a foredune crest existed both pre- and post-Sandy. 5) SUP_C2C_AreasVolLoss - data from supplementary material comparing volumetric loss among species Pre- to post-Sandy dune crest (ie crest to crest) 6) SUP_C2T_AreasVolLoss - data from supplementary material comparing volumetric loss among species post-Sandy crest to pre-Sandy dune toe (ie crest to toe) 7) SUP_slicesCtoC - data from supplementary material comparing incremental volumetric loss per 1m wide cross sectional slivers among species Pre- to post-Sandy dune crest (ie crest to crest) to relate to linear metric of erosion, dune crest transgression (DCT)8) SUP_slicesCtoT - data from supplementary material comparing incremental volumetric loss per 1m wide cross sectional slivers among species Pre- to post-Sandy dune crest (ie crest to crest) to relate to linear metric of erosion, dune crest transgression (DCT)<br><b>Columns Explained sheets 3-8</b><b>FID_Dune_Loss_Lines</b> = The parellel lines layer created perpendicular to the beach. Each line is 1 m from the next such that lines 3003 and 3004 are 1 m (north to south) from one another and lines 3003 and 3023 are 20 m from one another. Spatial autocorrelation must be accounted for for inclusion in statistical analyses. The smaller the FID# the further north the line is. <br><b>SpeciesFrontingDune </b>= Plant species stabilizing dune when Superstorm Sandy hit, <i>Ammophila breviligulata</i> (AB) or invasive <i>Carex kobomugi</i> (CK). <b> </b><b><br></b><b>MatchID_PairedSites </b>= the 14 paired sites as described in the main body of the paper where each pair is an area stabilized by AB and CK of equal size. Sample/stand size within pairs is equal, but not equal among sites. <br><b>2DSA - </b>macroscale metric of erosion as changes in 2D surface area (m<sup>2</sup>). Data in this column is the 2D area of the polygon of dune that was eroded from Superstorm Sandy.<br><b>VolumetricLoss</b> - classic measure of coastal erosion as the volumetric change incurred from a storm in m<sup>3</sup>.<b><br></b><b>DCT_Erosion_DuneLengthLost(m)</b> - Dune crest transgression - novel linear metric of erosion that is the microscale incremental erosion per m along dune where the east and west extent are the pre- and post-Sandy dune crest. Spatial autocorrelation must be accounted for for inclusion in statistical analyses.<br><b>BeachWidth(m)_PreSandy</b> - Pre-Sandy beach width where east extent is the threshold of elevation 0 m above sea level and west extent is the pre-Sandy dune crest. <br><b>Elevation(m)DuneCrest_PreSandy</b> - Elevation of the dune pre-Sandy as extracted from Wright et al. LIDAR data (http://pubs.usgs.gov/ds/767/html/home.html)
