This Monitoring Report incorporates the changes of shoreline position (1D) and the changes of dune/beach profiles (2D) in Gateway National Recreation Area from the spring of 2016 through the spring of 2017. Following established protocols, seasonal surveys generated data sets for subsequent comparisons. Although too early to identify trends of change, the data do provide a series of dimensions regarding the linear distances of shoreline position changes and both linear dimensions and cross-sectional areas of beach and dune features on the profiles. A variety of figures and tables portray the metrics derived from the monitoring programs for each of the seasonal surveys and the differences among the seasonal surveys for the span of one year. During this survey period, shoreline change was largely characterized by net annual erosion (landward displacement) with erosion taking place during the summer season and deposition (seaward displacement) or no change occurring during the winter season. Sheltered sites such as Plumb Beach and Breezy Point Bayside exhibited less shoreline change than exposed sites such as Sandy Hook and Breezy Point Oceanside. Profile change was characterized by a relatively stable dune, with the exception of net dune erosion at Great Kills and Fort Wadsworth and net dune accretion at Breezy Point Oceanside. Profile change in the beach was highly variable at every site, with a tendency towards net erosion and downdrift accretion. Detailed data analyses and interpretation of results will be included in Trend Reports to be published every five years.
