In 2018 and 2019 the Southeast Coast Network collected shoreline data at Fort Matanzas National Monument as a part of the NPS Vital Signs Monitoring Program. Monitoring was conducted following methods developed by the National Park Service Northeast Barrier Coast Network and consisted of mapping the high tide swash line using a global positioning system (GPS) unit in the spring of each year (Psuty et al. 2010). Shoreline change was calculated using the Digital Shoreline Analysis System (DSAS) developed by USGS (Theiler et al. 2008). Key findings from this effort are as follows A mean of 2,226.23 meters (m; 1.38 miles [mi])of shoreline were mapped from 2018 to 2019 with a mean horizontal precision of 10.63 centimeters (4.19 inches [in]). The mean shoreline distance change from 2018 to 2019 was -0.94 meters (-3.08 feet [ft]) with a standard deviation of 21.95 meters (72.01 ft). The shoreline change distance ranged from -51.29 meters to 67.53 meters (-168.28 to 221.56 ft). Three high erosion areas were identified in the study area. 21% of the transects were located in areas of erosion beyond the uncertainty range of the data (±10 meters [32.81 ft]), which equates to 430 meters (1,410.76 ft) of the surveyed shoreline distance. Three accretion areas were present in the 2018 to 2019 shoreline survey analysis beyond the uncertainty range of the data (±10 meters [32.81 ft]).
