title: Projected Seafloor Elevation Along the Florida Reef Tract From Big Pine Key to Marquesas Key, Florida-25 Years From 2011 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 Key West, 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 Big Pine Key to Marquesas Key, FL that was modified from the NOAA National Centers for Environmental Information (NCEI) Key West coastal DEM (NOAA, 2011) to project future seafloor elevation (from 2011) along the Key West section of the Florida Reef Tract. Grid resolution for the DEM is 1/3 arc second (approximately 10 meters). Data were collected under Florida Keys National Marine Sanctuary permit FKNMS-2016-068. For more information visit: Yates, K. K., Zawada, D. G., Smiley, N. A., and Tiling-Range, G., 2017, Divergence of seafloor elevation and sea level rise in coral reef ecosystems: Biogeosciences, v. 14, p. 1739-1772, https://doi.org/10.5194/bg-14-1739-2017.

title: Archive of Chirp Subbottom Profile Data Collected in 2016 From the Northern Chandeleur Islands, Louisiana

description: As part of the Barrier Island Evolution Research Project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a nearshore geophysical survey around the northern Chandeleur Islands, Louisiana, in June of 2016. The objective of the project is to improve the understanding of barrier island geomorphic evolution, particularly storm-related depositional and erosional processes that shape the islands over annual to interannual timescales (1-5 years). Collecting geophysical data can help researchers to identify relationships between the geologic history of the island and its present-day morphology and sediment distribution. High-resolution geophysical data collected along this rapidly changing barrier island system can provide a unique time-series dataset to further the analyses and geomorphological interpretations of this and other coastal systems, improving researchers understanding of coastal response and evolution over medium-term time scales (months to years). This data release serves as an archive of subbottom profile and navigation data collected in June 2016 offshore of the northern Chandeleur Islands, during USGS Field Activity Number 2016-335-FA. 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.

title: Archive of Chirp Subbottom Profile Data Collected in June 2018 From Fire Island, New York

description: Researchers from the U.S. Geological Survey (USGS) conducted a long-term, coastal morphologic-change study at Fire Island, New York, prior to and after Hurricane Sandy impacted the area in October 2012. The Fire Island Coastal System Change project objectives include understanding the morphologic evolution of the barrier island system on a variety of time scales (months to centuries) and resolving storm-related impacts, post-storm beach response, and recovery. In June 2018, scientists from the USGS St. Petersburg Coastal and Marine Science Center conducted geophysical surveys on Fire Island to characterize and quantify spatial variability in the subaerial geology with the goal of subsequently integrating onshore geology with other shoreface datasets also collected under the Disaster Relief Appropriations Act of 2013, using the U.S. Department of the Interior Hurricane Sandy supplemental funding. This data release serves as an archive of high-resolution subbottom profiles and differential global positioning system (DGPS) navigation data collected from beach and nearshore environments on Fire Island, June 2-16, 2018 (USGS Field Activity Number 2018-322-FA). USGS scientists created a purpose-built, towed sled system to mount the chirp profiler (just below the water's surface) and enable launching and recovery from the foreshore. The seismic sled was also configured to help ensure the quality of data collected in exceedingly shallow water depths, such as those observed near the shoreline and surf zone.

title: Projected Seafloor Elevation Along the Florida Reef Tract From Big Pine Key to Marquesas Key, Florida-75 Years From 2011 Based on Historical Rates of Mean Erosion

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 Key West, 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 erosion were calculated for 13 habitat types found in the UFK reef tract. The annual rate of mean erosion for each habitat type was applied to a digital elevation model (DEM) extending from Big Pine Key to Marquesas Key, FL that was modified from the NOAA National Centers for Environmental Information (NCEI) Key West coastal DEM (NOAA, 2011) to project future seafloor elevation (from 2011) along the Key West section of the Florida Reef Tract.

title: Looe Key, Florida, 2004-2016 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 2004 and 2016 at Looe Key coral reef near Big Pine Key, Florida, within a 16.37 square-kilometer area. USGS SPCMSC staff used seafloor elevation-change data from Yates and others (2019) derived from an elevation-change analysis between two elevation datasets acquired in 2004 and 2016 using the methods of Yates and others (2017). A seafloor stability threshold was determined for the 2004-2016 Looe Key elevation-change dataset based on the vertical uncertainty of the 2004 and 2016 digital elevation models (DEMs). 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 (4,086,712 data points at 2-m horizontal resolution) based on the amount of erosion and accretion during the 2004 to 2016 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.
