The Shoreline Position Trend Report applies to the surveys conducted from spring 2007 through spring 2012. It has 5-year data sets on most of the ocean-facing shorelines in Gateway, and shorter temporal spans on the bay-facing shorelines. Data sets include annual and 5-year shoreline position changes in a spatial format, as well as histograms and statistical data describing mean values of change and standard deviation, following the model presented in Psuty et al. (2010b). Because of the variable inputs of sediment to the alongshore transport system in the various units from updrift sources, there is no common direction of shoreline displacement throughout the park. Engineering structures along the beach and adjacent to inlets have further altered the shoreline position responses in much of Gateway. Some of the variation is the product of Hurricane Irene that created considerable inland displacement of the shoreline position in the fall 2011 survey, followed by considerable recovery in the spring 2012 survey. These survey results are an excellent first product of the shoreline position monitoring called for in the protocol for shoreline coastal geomorphological monitoring in the Northeast Coastal and Barrier Network. This 5-year trend report is augmented by a more detailed seasonal and annual report covering the period 2011 - spring 2012 as an appendix.
