The Florida Hydrography Dataset (FHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the state's surface water drainage system. The FHD is based on the original National Hydrography Dataset (NHD) data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution FHD, generally developed at 1:5,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) The FHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The FHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.

These data were automated to provide an accurate high-resolution historical shoreline of Lake Okeechobee, Florida suitable as a geographic information system (GIS) data layer. These data are derived from shoreline maps that were produced by the NOAA National Ocean Service including its predecessor agencies which were based on an office interpretation of imagery and/or field survey.

The map shows the bottom types for Florida Bay that resulted from site surveys and boat transects (summer 1996-January 1997) compared with aerial photographs (December 1994-January 1995) and SPOT satellite imagery (1987).

The South Florida Seagrass Fish and Invertebrate Assessment Network (FIAN) is an element of the Monitoring and Assessment Plan (MAP) a part of RECOVER, the Restoration, Coordination and Verification Program of the Comprehensive Everglades Restoration Plan (CERP). FIAN is an element of the Southern Coastal System module of MAP (MAP activities 3.2.3.5 and 3.2.4.5). FIAN monitors seagrass-associated fish and invertebrate (penaeid and caridean shrimp and crabs) communities present in shallow waters of South Florida; the pink shrimp, Farfantepenaeus duorarum, as an indicator of restoration success, is a species of special interest. FIAN represents the first region-wide view of these communities and the pink shrimp.

The FIAN monitoring component of the Southern Estuaries module of MAP is designed to support the four broad objectives of MAP: (1) to establish a pre-CERP reference state, including variability, for each of the performance measures; (2) to determine the status and trends in the performance measures; (3) to detect unexpected responses of the ecosystem to changes in stressors resulting from CERP activities; and (4) to support scientific investigations designed to increase ecosystem understanding, cause-and-effect, and interpretation of unanticipated results.

The data developed in FIAN will be used to evaluate the success of CERP by contributing to the assessment of the estuarine response to restoration-related modifications to upstream hydrology in the freshwater Everglades. At present, FIAN provides input to the pink shrimp performance measure (RECOVER, 2004; SFWMD 2005). The pink shrimp emerged as an ecosystem attribute to be monitored from the Florida and Biscayne Bay conceptual ecological models. More generally these data will be used to relate seagrass-associated faunal communities to habitat and environmental conditions in South Florida shallow water estuaries.

FIAN is closely coupled with the MAP seagrass monitoring project FHAP-SF and other seagrass monitoring programs in South Florida, e.g. DERM. Close coupling with seagrass monitoring recognizes the importance of shallow seagrass systems to the function of coastal waters and their vulnerability to anthropogenic change. Estuaries downstream from CERP projects will be affected by changes in the quantity, timing, and distribution of freshwater inflows. Associated changes in estuarine salinity regimes and subsequent, long-term, changes in benthic vegetation are anticipated. We hypothesize that abundance and diversity of seagrass-associated fish and invertebrates including the pink shrimp in nearshore waters of South Florida will increase as the overlap of favorable salinity conditions with favorable seagrass/algal habitat increase.

Rates of long-term and short-term shoreline change were generated in a GIS with the Digital Shoreline Analysis System (DSAS) version 2.0, an ArcView extension developed by the U.S. Geological Survey (USGS) in cooperation with TPMC Environmental Services. The extension is designed to efficiently lead a user through the major steps of shoreline change analysis. This extension to ArcView contains three main components that define a baseline, generate orthogonal transects at a user-defined separation along the coast, and calculate rates of change (linear regression, endpoint rate, average of rates, average of endpoints, jackknife).

These data were collected under a cooperative mapping program between the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration Coastal Services Center (NOAA\CSC), and the Apalachicola National Estuarine Research Reserve (NERR). The primary objectives of this program were to collect marine geophysical data to develop a suite of seafloor maps to better define the extent of oyster habitats, the overall seafloor geology of the bay and provide updated information for management of this resource. In addition to their value for management of the bay's oyster resources, the maps also provide a geologic framework for scientific research and the public. High-resolution bathymetry, backscatter intensity, and seismic profile data were collected over 230 square kilometers of the floor of the bay. The study focused on the Apalachicola Bay and Western St. George Sound portions of the estuary in mostly in depths > 2.0 meters.

This GIS data set represents the state bounds of Florida, including both land and water areas. The offshore boundary was acquired from the National Oceanic and Atmospheric Administration (NOAA) Submerged Lands Act shapefile. The state borders between Florida and Georgia and Florida and Alabama were digitized by FWRI staff using Digital Raster Graphic (DRG) maps.

Attempts to stabilize the shore can greatly influence rates of shoreline change. Beach nourishment in particular will bias rates of observed shoreline change toward accretion or stability, even though the natural beach, in the absence of nourishment, would be eroding.

Trembanis and Pilkey (1998) prepared a summary of identifiable beach nourishment projects in the Gulf Coast region that had been conducted before 1996. Those records were used to identify shoreline segments that had been influenced by beach nourishment. Supplemental information regarding beach nourishment was collected from agencies familiar with nourishment projects in the State. All records were compiled to create a GIS layer depicting the spatial extents of nourishment projects within the State.

The objective of this research was to collect new bathymetry for all of Florida Bay, digitize the historical shoreline and bathymetric data, compare previous data to modern data, and produce maps and digital grids of historical and modern bathymetry.

Detailed, high-resolution maps of Florida Bay mudbank elevations are needed to understand sediment dynamics and provide input into water quality and circulation models. The bathymetry of Florida Bay had not been systematically mapped in nearly 100 years, and some shallow areas of the bay have never been mapped. An accurate, modern bathymetric survey provides a baseline for assessing future sedimentation rates in the Bay, and a foundation for developing a sediment budget. Due to the complexity of the Bay and age of existing data, a current bathymetric grid (digitally derived from the survey) is critical for numerical models. Numerical circulation and sediment transport models being developed for the South Florida Ecosystem Restoration Program are being used to address water quality issues in Florida Bay. Application of these models is complicated due to the complex seafloor topography (basin/mudbank morphology) of the Bay. The only complete topography data set of the Bay is 100 years old. Consequently, an accurate, modern seafloor bathymetry map of the Bay is critical for numerical modeling research. A modern bathymetry data set will also permit a comparison to historical data in order to help access sedimentation rates within the Bay.

This dataset is a point shapefile showing the distribution of species richness, Shannon's Diversity (H), and Shannon's Evennes (J) along the Florida Keys (Key Biscayne to Key West based on data collected from 1980 through 2010. Point estimates of species richness, Shannon's diversity (H), and Evenness were derived from Reef Visual Census (RVC) Surveys. RVC surveys were conducted using a cooperative multi-agency Reef Fish Monitoring Protocol for the Florida Keys Coral Reef Ecosystem (Menza et al., 2006; Brandt et al., 2009). Data on fish occurence and abundance were collcted using a 200-m x 200-m polygon grid developed by The University of Miami's Rosenstiel School of Marine and Atmospheric Science (UM-RSMAS) and the National Marine Fisheries Southeast Fisheries Science Center (NFMS-SEFSC). The grid forms the basis for a two-stage stratified random sampling allocation scheme that was developed to estimate important metrics for living resource populations (e.g., corals and reef fishes) in Southwest Florida, extending from Martin County in the northeast through the Florida Keys to the Dry Tortugas in the southwest (Jeffrey et al., 2012; Ault et al., In Press).

This dataset is part of an spatial analytical framework that was developed: 1) to describe the spatial distribution patterns of living resources (reef fish, algae, corals, gorgonians, sponges, and other benthic invertebrates along the Florida Coral Reef Tract (FCRT); 2) document temporal changes in benthic communities throughout the region, and 3) inform the Florida Keys National Marine Sanctuary Marine Zoning and Regulatory Review process. The timeline for the review process is November 2011 through Summer 2015.
