title: Looe Key, Florida, 1938-2004 Seafloor Elevation Stability Models, Maps, and Tables

description: The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted research to identify areas of seafloor elevation stability and instability based on elevation changes between the years of 1938 and 2004 at Looe Key coral reef near Big Pine Key, Florida, within a 19.06 square-kilometer area. USGS SPCMSC staff used seafloor elevation-change data from Yates and others (2017a) derived from an elevation-change analysis between two elevation datasets acquired in 1938 and 2004 using the methods of Yates and others (2017b). A seafloor stability threshold was determined for the 1938-2004 Looe Key elevation-change dataset based on the vertical uncertainty of the 1938 historical hydrographic survey and 2004 digital elevation model (DEM). Five stability categories (which include, Stable: 0.0 meters (m) to plus/minus 0.24 m or 0.0 m to plus/minus 0.49 m; Moderately stable: plus/minus 0.25 m to plus/minus 0.49 m; Moderately unstable: plus/minus 0.50 m to plus/minus 0.74 m; Mostly unstable: plus/minus 0.75 m to plus/minus 0.99 m; and Unstable: plus/minus 1.00 m to Max/Min elevation change) were created and used to define levels of stability and instability for each elevation-change value (1,687 data points) based on the amount of erosion and accretion during the 1938 to 2004 time period. Seafloor-stability point and triangulated irregular network (TIN) surface models were created at five different elevation-change data resolutions (1st order through 5th order) with each resolution becoming increasingly more detailed. The stability models were used to determine the level of seafloor stability at potential areas of interest for coral restoration and ten habitat types found at Looe Key. Stability surface (TIN) models were used for areas defined by specific XY geographic points, while stability point models were used for areas defined by bounding box coordinate locations. This data release includes ArcGIS map packages containing the binned and color-coded stability point and surface (TIN) models, potential coral restoration locations, and habitat files; maps of each stability model; and data tables containing stability and elevation-change data for the potential coral restoration locations and habitat types. Data were collected under Florida Keys National Marine Sanctuary permit FKNMS-2016-068. Coral restoration locations were provided by Mote Marine Laboratory under Special Activity License SAL-18-1724-SCRP.

title: Multibeam Bathymetry Data Collected in 2018 from Grand Bay and Point Aux Chenes Bay Alabama/Mississippi

description: The U.S Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted an ellipsoidally referenced survey using a multibeam echosounder within Grand Bay and Point Aux Chenes Bay, Alabama/Mississippi October 22-23, 2018. The survey is bridged between the former Sea level and Storm Impacts on Estuarine Environments and Shorelines project (SSIEES), which focused on the influence of marsh shoreline geometry on erosion and deposition patterns, and the current Estuarine and Marsh Geology Research Project (EMRG) which focuses on evaluating the linkage between marsh shoreline metrics and marsh geology. To facilitate mapping of the eroding marsh edges at locations of interest around the bay, the multibeam echosounder was horizontally tilted 62.5 degrees. This dataset includes the processed elevation point data (x,y,z), as derived from a 1-meter bathymetric grid, in the native format of the World Geodetic System of 1984 (WGS84). The data were transformed horizontally into the North American Datum of 1983 (NAD83) and vertically to the North American Vertical Datum of 1988 (NAVD88), using the GEOID12A model, and these files are also provided.

title: Projected Seafloor Elevation Along the Florida Reef Tract From Deerfield Beach to Homestead, Florida-50 Years From 2014 Based on Historical Rates of Mean Elevation Change

description: The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify the combined effect of all constructive and destructive processes on modern coral reef ecosystems by projecting future regional-scale changes in seafloor elevation for several sites along the Florida Reef Tract, Florida (FL) including the shallow seafloor along the coast of Miami, FL. USGS staff used historical bathymetric point data from the 1930's (National Oceanic and Atmospheric Administration (NOAA) Office of Coast Survey, see Yates and others, 2017) and light detection and ranging (lidar)-derived data acquired in 2002 (Brock and others, 2006, 2007) to calculate historical seafloor elevation changes in the Upper Florida Keys (UFK) (Yates and others, 2017). Using those changes in seafloor elevation, annual rates of elevation change were calculated for 13 habitat types found in the UFK reef tract. The annual rate of mean elevation change for each habitat type was applied to a digital elevation model (DEM) extending from Deerfield Beach to Homestead, FL that was modified from the NOAA National Centers for Environmental Information to project future seafloor elevation (from 2014) along the Miami section of the Florida Reef Tract. Grid resolution for the DEM is 1/3 arc second (approximately 10 meters). For more information visit: Yates, K. K., Zawada, D. G., Smiley, N.

title: Archive of Chirp Subbottom Profile Data Collected in 2017 from the Louisiana Chenier Plain

description: Scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted nearshore geophysical surveys around the eastern and western Chenier Plain, Louisiana, in 2017. Data were collected under the Barrier Island Coastal Monitoring (BICM) program, an ongoing collaboration between the State of Louisiana Coastal Protection and Restoration Authority (CPRA), the University of New Orleans (UNO) Pontchartrain Institute for Environmental Sciences (PIES), and the USGS. The objective of this study was to document the changing morphology of the coastal environment by compiling historical shoreline bathymetric datasets and comparing them to bathymetric data collected during the BICM project. At the same time, subsurface geophysical data were collected to investigate the geomorphology and geologic controls on barrier-shoreline evolution. Collecting geophysical data can help researchers to identify relationships between the geologic history of the barrier shoreline and its present-day morphology and sediment distribution. This data release serves as an archive of subbottom profile and navigation data acquired offshore of the Chenier Plain, during USGS Field Activity Numbers 2017-323-FA (Project ID: 17BIM01, June 2-10) and 2017-324-FA (17BIM05, July 2). Data products, including unprocessed digital chirp subbottom data, trackline map, navigation files, processed profile images, geographic information system (GIS) files and formal Federal Geographic Data Committee (FGDC) metadata, and field logs are provided.
