Abstract:
Critical habitat constitutes areas considered essential for the conservation of a listed species. These data identify, in general critical habitat areas for the Northwest Atlantic Ocean Distinct Population Segment of Loggerhead sea turtle (Caretta caretta), providing notice to the public and managers of the importance of the areas to the conservation of this species. Special protections and/or restrictions are possible in areas where Federal funding, permits, licenses, authorizations, or actions occur or are required. We describe the physical and biological features (PBF), including: 1) nearshore reproductive habitat; 2) breeding habitat; 3) migratory habitat; 4) winter habitat; and 5) Sargassum habitat. 1) We describe the physical and biological features (PBF) of nearshore reproductive habitat as a portion of the nearshore waters adjacent to nesting beaches that are used by hatchlings to egress to the open-water environment as well as by nesting females to transit between beach and open water during the nesting season. Primary constituent elements (PCEs) that support this habitat are the following: (i) Nearshore waters directly off the highest density nesting beaches, as identified in 78 FR 43006, July 18, 2003, to 1.6 km (1 mile) offshore; (ii) Waters sufficiently free of obstructions or artificial lighting to allow transit through the surf zone and outward toward open water; and (iii) Waters with minimal man made structures that could promote predators (i.e., nearshore predator concentration caused by submerged and emergent offshore structures), disrupt wave patterns necessary for orientation, and/or create excessive longshore currents. 2) We describe the physical and biological features (PBF) of breeding habitat as sites with high densities of both male and female adult individuals during the breeding season. Primary constituent elements (PCEs) that support this habitat are the following: (i) High densities of reproductive male and female loggerheads; (ii) Proximity to primary Florida constricted migratory corridor; and (iii) Proximity to Florida nesting grounds. 3) We describe the physical and biological features (PBF) of constricted migratory habitat as high use migratory corridors that are constricted (limited in width) by land on one side and the edge of the continental shelf and Gulf Stream on the other side. Primary constituent elements (PCEs) that support this habitat are the following: (i) Constricted continental shelf area relative to nearby continental shelf waters that concentrate migratory pathways; and (ii) Passage conditions to allow for migration to and from nesting, breeding, and/or foraging areas. 4) We describe the physical and biological features (PBF) of winter habitat as warm water habitat south of Cape Hatteras, North Carolina near the western edge of the Gulf Stream used by a high concentration of juveniles and adults during the winter months. Primary constituent elements (PCEs) that support this habitat are the following: (i) Water temperatures above 10° C from November through April; (ii) Continental shelf waters in proximity to the western boundary of the Gulf Stream; and (iii) Water depths between 20 and 100 meters. 5) We describe the physical and biological features (PBF) of Sargassum habitat as developmental and foraging habitat for young loggerheads where surface waters form accumulations of floating material, especially Sargassum. Primary constituent elements (PCEs) that support this habitat are the following: (i) Convergence zones, surface-water downwelling areas, the margins of major boundary currents (Gulf Stream), and other locations where there are concentrated components of the Sargassum community in water temperatures suitable for the optimal growth of Sargassum and inhabitance of loggerheads; (ii) Sargassum in concentrations that support adequate prey abundance and cover; (iii) Available prey and other material associated with Sargassum habitat including, but not limited to, plants and cyanobacteria and animals native to the Sargassum community such as hydroids and copepods; and (iv) Sufficient water depth and proximity to available currents to ensure offshore transport (out of the surf zone), and foraging and cover requirements by Sargassum for post-hatchling loggerheads, i.e., >10 meters depth.
Purpose:
The purpose of these data is to visually represent the critical habitat areas for GIS analysis and display.

Process_Description:
1.6 km buffers were created around the nesting beach critical habitat line features published in the Federal Register Volume 79, pg. 39755, July 10, 2014. The buffers were clipped to include polygons of only the portion seaward of the nesting beach critical habitat line features portion. Adjacent seaward nearshore reproductive polygons within 1.6 km of each other were connected to make the final nearshore reproductive units using a shoreline vector digitized using the ArcGIS Online World Imagery Basemap as a reference (zoomed to an approximate scale of 1:24000) or by delineating a straight line from the end of one beach to the beginning of another (either from island to island or across an inlet or the mouth of an estuary).

Process_Description:
The northern breeding polygon located in the waters just south of Cape Canaveral, FL was generated using a minimum convex polygon (MCP) created from positional data from breeding adult male loggerheads. Detailed information regarding the creation of the MCP can be found in M.D. Arendt et al. “Distributional patterns of adult male loggerhead sea turtles (Caretta caretta) in the vicinity of Cape Canaveral, Florida, USA during and after a major annual breeding aggregation”, Marine Biology (2012) 159:101–112. The MCP was clipped using a shoreline vector digitized using the ArcGIS Online World Imagery Basemap (zoomed to an approximate scale of 1:24000) as a reference to include only the seaward portion. The southern breeding polygon stretches along the coast of Florida from the Martin/Palm Beach county line (29.97° N latitude) to the western edge of the Marquesas Keys (82.17° W longitude). The seaward boundary of the polygon is the 200 meter depth contour generated from 30 arc-second GEBCO bathymetry data. The landward boundary of the polygon was created using a combination of shoreline digitized using the ArcGIS Online World Imagery Basemap (zoomed to an approximate scale of 1:24000) as a reference and line features from the 2012 TIGER/Line® roads shapefile. For the landward boundary, digitized shoreline is used from the Martin/Palm Beach county line south to Key Largo. At approximately 25.17° N latitude, the digitized shoreline is connected to a line feature from the roads shapefile representing US Route 1. Heading south, the US Route 1 line feature from the roads shapefile serves as the landward boundary until it ends in Key West. The end of the US Route 1 line feature is connected back to the digitized shoreline, which serves as the landward boundary to the western edge of the Marquesas Keys. The landward boundary at the Martin/Palm Beach county line is connected to the seaward boundary using a segment that extends due east, while the landward boundary at the western edge of the Marquesas Keys connects to the seaward boundary using a segment that extends due south.

Process_Description:
The landward boundary of northern constricted migratory habitat polygon consists of shoreline digitized using the ArcGIS Online World Imagery Basemap as a reference (zoomed to an approximate scale of 1:24000) from 36.0° N latitude to Cape Lookout (34.58° N latitude). The seaward boundary of the northern constricted migratory habitat polygon is the 200 meter depth contour generated from 30 arc-second GEBCO bathymetry data. The landward boundary of the northern constricted migratory habitat polygon connects to the seaward boundary with due east segments at 36.0 and 34.58° N latitudes. The landward boundary of the southern constricted migratory habitat polygon was created using a combination of shoreline digitized using the ArcGIS Online World Imagery Basemap (zoomed to an approximate scale of 1:24000) as a reference and line features from the 2012 TIGER/Line® roads shapefile. For the landward boundary, digitized shoreline is used from the tip of Cape Canaveral, FL (28.46° N latitude) south to Key Largo. At approximately 25.17° N latitude, the digitized shoreline is connected to a line feature from the roads shapefile representing US Route 1. Heading south, the US Route 1 line feature from the roads shapefile serves as the landward boundary until it ends in Key West. The end of the US Route 1 line feature is connected back to the digitized shoreline, which serves as the landward boundary to the western edge of the Marquesas Keys. The northern border stretches from the shoreline at 28.46° N latitude to the 30 meter depth contour. From the 30 meter depth contour at 28.46° N latitude, the seaward boundary stretches to the 200 meter depth contour at 27.0° N latitude. The seaward boundary continues south and west along the 200 meter depth contour until it reaches the western edge of the Marquesas Keys at 82.17° W longitude. The landward boundary of the southern constricted migratory habitat polygon at the western edge of the Marquesas Keys connects to the seaward boundary using a segment that extends due south.

Process_Description:
The Gulf of Mexico Sargassum habitat polygon was delineated using depth contours generated from 30 arc-second GEBCO bathymetry data, the United States Exclusive Economic Zone (U.S. EEZ) boundary, gridded mean summer sea surface currents (1993-2011) calculated from 1/3-degree Ocean Surface Current Analyses-Real time (OSCAR) data, and the Gulf Loop Current and Gulf Stream as modeled by the Naval Oceanographic Office from 2010 sea surface temperature data. The 10 meter depth contour starting at the mouth of South Pass of the Mississippi River and proceeding west and south to the outer boundary of the U.S. EEZ makes up the northern and western boundaries of the polygon. The southern boundary consists of the U.S. EEZ from the 10 meter depth contour off of Texas to the Gulf of Mexico-Atlantic border (83° W longitude). The eastern boundary follows the 10 m depth contour from the mouth of South Pass of the Mississippi River at 28.97° N latitude, 89.15° W longitude, in a straight line to the northernmost boundary of the Loop Current (28° N latitude, 89° W longitude) and then along the eastern edge of the Loop Current roughly following the velocity of 0.101-0.20 m/second (from the gridded mean summer sea surface currents) to the Gulf of Mexico-Atlantic Ocean border (24.58° N latitude, 83° W longitude). The delineation between the Gulf of Mexico and the Atlantic Ocean starts near the Dry Tortugas at 24.58° N latitude, 83° W longitude, and proceeds southward along 83° W longitude to the outer boundary of the U.S. EEZ (23.82° N latitude). The Atlantic Ocean Sargassum habitat polygon was delineated using the boundaries of the breeding and migratory critical habitat polygons, depth contours generated from 30 arc-second GEBCO bathymetry data, the United States Exclusive Economic Zone (U.S. EEZ) boundary, gridded mean summer sea surface currents (1993-2011) calculated from Ocean Surface Current Analyses-Real time (OSCAR) data, and the Loop Current and Gulf Stream as modeled by the Naval Oceanographic Office from 2010 sea surface temperature data. The polygon has as its outer boundary the U.S. EEZ, starting at the Gulf of Mexico-Atlantic border (23.82° N latitude, 83° W longitude) and proceeding east and north until the U.S. EEZ coincides with the Gulf Stream at 37.84° N latitude, 70.59° W longitude. The inner boundary of the polygon starts at the Gulf of Mexico-Atlantic border (24.58° N latitude, 83° W longitude) to the outer edge of the breeding/migratory critical habitat at 24.34° N latitude, 82.16° W longitude, along the outer edge of the corridor (following the 200 m depth contour) until it coincides with the breeding habitat off of Cape Canaveral at 27.97° N latitude, 80.14° W longitude, and from there roughly follows the velocity of 0.401-0.50 m/second from the gridded mean summer sea surface currents until it coincides with the outer edge of the U.S. EEZ at 37.84° N latitude, 70.59° W longitude.
