 "description": "This layer shows the density of moored vessels in 2012 through 2014.This project conducted aerial (helicopter) surveys to map vessel locations and charcteristics to determine use intensity, anchoring pressure, and predominant activities over the Southeast Florida region, and to associate use level with specific areas of the coral reef tract and other submerged habitat types.\nVessel information (location, type, length, and activity) and passenger information (activity) were collected for 3579 vessels that were observed off of Miami-Dade and Broward counties during periods of low, medium, and high use between 4/29/2008 and 11/19/2009 (CRUPS project) and between 7/4/2012 and 7/30/2014 (Mooring Buoy Project, or MBP). Three data collection (helicopter) flights occurred during each use level, and for each project. For each use level (and project) one flight occurred in the spring, one in the summer, and one in the fall. The design was selected to determine if a seasonal component in use patterns exists. An additional (10th) flight was added for the Florida spiny lobster \u201cmini-season\u201d during both projects. The dataset was used in two studies. The first study had as its goal an initial assessment of vessel use patterns on the natural reefs of the southeast Florida region (Miami-Dade, Broward, Palm Beach, and Martin counties). In addition, the researchers sought to develop methods that would form the basis for a standardized, repeatable approach to monitoring and characterizing the coral reef usage patterns by recreational and commercial vessels. The second study sought to determine if anchoring patterns and coral reef damage had changed as a result of installation of mooring buoys in Miami-Dade County. Ultimately, the patterns described from the data and the methods developed are meant to form a tool for managers to use in conserving and protecting the coral reefs of southeast Florida.",
