Marsh habitat change analysis for the Point Aux Chenes and Grand Bay Estuaries in Mississippi and Alabama from 1848 to 2022
공공데이터포털
Over time, as sea levels rise and land subsides, marsh transgression can occur. As shorelines erode and the marsh slowly transgresses landward into the upland, valuable coastal habitat simultaneously is lost and gained. If the shoreline erosion is faster than the rate of upland transgression, the result is a net loss in coastal wetlands. This dataset represents a marsh area change analysis for the Point Aux Chenes and Grand Bay estuaries in Mississippi and Alabama from 1848-1957/1958, 1848-2019/2022, and 1957/1958-2019/2022. Classified habitats are also included for 1848, 1957/1958 and 2022. Shoreline and upland boundary positional data were obtained from multiple data sources, including National Oceanic and Atmospheric Administration (NOAA) topographic sheets (t-sheets) and WorldView 2 high resolution satellite imagery. Two dates were chosen for the 1957/1958 (henceforth referred to as 1957), and 2019/2022 (henceforth be referred to as 2022) to provide complete coverage. Shorelines and upland lines were converted into raster data (.tif) to calculate marsh habitat area change over time. This data release contains a raster data for 1848, 1957, and 2022, as well as change rasters for 1848-1957, 1957-2022, and 1848-2022.

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring efforts to determine the efficacy of these efforts. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 390 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) in Louisiana rely on monitoring efforts to determine the efficacy of these efforts. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 390 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites. This dataset consists of a matrix of four land-water products (2005, 2008, 2012, and 2016). The resulting matrix has 16 possible classes defined by the combination of land and water categories on those four dates.
