Metrics of Resilience and Recovery in Jamaica Bay Unit, Gateway National Recreation Area

Psuty NP. Metrics of Resilience and Recovery in Jamaica Bay Unit, Gateway National Recreation Area. 2014-2016

This report documents an analysis of linear feature displacement, elevation change, and volumetric change over time at sites within the Jamaica Bay Unit, Gateway National Recreation Area. This analysis provides data-driven information regarding the resilience of the beach and dune system along West Pond South and the ability of the system to recover after storms. The West Pond South survey site is an area of interest due to the adjacent breach, formed during Hurricane Sandy, and limited anthropogenic influence. The Jamaica Bay resilience project uses the Coastal Landform Elevation Model Protocol to create a three-dimensional subaerial topography model of the West Pond South survey site (Psuty et al., 2017). Seasonal survey data spanning from the winter of 2014 to the summer of 2016 were supplemented with LiDAR datasets from August 2010 and July 2013 to monitor the impacts of and recovery from Hurricane Sandy (October 2012). Spatial displays of elevation change, volumetric change, shoreline and foredune linear feature change, and associated metrics are presented within this report.
