February 2020 National Wetlands Inventory, Mississippi Barrier Islands Habitat Classification: (Cat Island, Ship Island, Petit Bois Island and Horn Island) This data set consists of digital data describing wetlands and uplands habitats for the Mississippi Coastal Improvements Program (MsCIP) area, consisting of Cat, Ship, Horn and Petit Bois Islands for the year 2020. Wetlands were classified using the Cowardin, et al., wetlands classification scheme to the level of freshwater and tidal, salinity modifiers. Uplands were classified using a customized classification scheme which can be cross-referenced to Anderson, et. al. For this dataset, upland dunes were delineated as areas at or above 1.524 meters (5 feet) as determined in the Lidar data that was referenced without modification for this classification. With this elevation criteria some delineated upland dune features...

Oyster castles were constructed as a part of a living shoreline project along Gandys Beach in 2016 in response to the damage by Hurricane Sandy in 2012. Wave, current and sediment data were collected, and field topographic and bathymetric surveys were conducted from January 2018 to April 2018. Fine resolution topographic and bathymetric data is needed to assess shoreline structure effectiveness in terms of wave and current energy reduction,...

Two field trips were carried out to the fully-submerged cave system located 6.6 km inland from the coastline in January 2015 and January 2016. Vertical chemical profiles across the water column haloclines were obtained using the OctoPiPi (OPP), a high-resolution water sampler built by the U.S. Geological Survey (USGS).

Post-hurricane marsh restoration efforts have included sediment deposition, planting of vegetation, and restoring tidal hydrology. The work presented here is part of a larger project funded by the National Fish and Wildlife Foundation (NFWF) to monitor the post-restoration ecological resilience of coastal ecosystems in the wake of Hurricane Sandy. The U.S. Geological Survey Woods Hole Coastal and Marine Science Center made in-situ observations during 2018-2019 and 2022-2023 at two sites: Thompsons Beach, NJ and Stone Harbor, NJ.

For each 0.5-by-0.5 m plot, the following data were collected: 1) percent cover by vegetation species; 2) percent cover by vegetation classes based on height (that is, carpet, herbaceous, and woody); 3) mean height of the dominant species; 4) water depth; 5) marsh class based on dominant vegetation species; and 6) location and elevation (that is, northing, easting, and elevation).
