Use of existing marine protected areas (MPAs) by far-ranging marine turtles can be determined using satellite telemetry. Because of a lack of information on MPA use by marine turtles in the Gulf of Mexico, we used satellite transmitters in 2010 and 2011 to track movements of 11 adult female breeding green turtles (Chelonia mydas) tagged in Dry Tortugas National Park (DRTO), in the Gulf of Mexico, south Florida, USA. Throughout the study period, turtles emerged every 9–18 days to nest. During the intervals between nesting episodes (i.e., inter-nesting periods), the turtles consistently used a common core-area within the DRTO boundary, determined using individual 50% kernel-density estimates (KDEs). We mapped the...
Data in this collection include the abundance of organisms observed during Self-Contained Underwater Breathing Apparatus (SCUBA) diver surveys conducted by Reef Check California (RCCA) volunteers in nearshore, rocky reef environments along the coast of California between 2006 and 2019. After completing training through RCCA, volunteer teams of divers select survey sites and perform surveys according to RCCA standard protocol. Since its inception in 2006, RCCA trained divers have conducted thousands of these surveys at hundreds of sites, including sites within more than 50 State Marine Reserves and State Marine Conservation Areas. At each site, buddy teams of divers conduct 18, 30 m x 2 m benthic transects to monitor...
This dataset is an inventory of Marine Protected Areas in the Wider Caribbean region with their point locations. This list was developed under the Reefs at Risk Caribbean project and relied on literature and other studies. Gathering information on MPAs across the region is very difficult and, as such, this list does not pertain to be exhaustive or complete. Additionally, as the dataset was developed for the purpose of gaining a better understanding of protection afforded coral reefs - there may be some selective bias towards those directly relevant to coral reefs (for example, no protected turtle nesting beaches are in the dataset). However, at the time of production of this inventory, spatial information and assessment...
This Marine Protected Areas (MPA) coverage developed by the Coastal Zone Management Institute is based on bounding coordinates provided by Government of Belize Statutory Instruments which delineate the boundaries of the various protected areas dotting the marine landscape. While originally developed in 2003, the dataset is also current as of 2004, as the network remained unchanged until February of 2005 with the declaration of the St. George's Caye Mangrove Reserve (not included in this dataset).
Percent of marine ecoregion area formally protected. A global listing of 5,045 marine protected areas was developed by Spalding et al. (2008) using the World Database on Protected Areas (UNEP/IUCN 2008) and data from the related work undertaken at the University of British Columbia (Wood et al. 2008). These data were overlain on the map of marine ecoregions (shelf areas only) to derive total area coverage statistics. It is not currently possible to assess the effectiveness of MPAs at a global scale, so the map shows an optimistic assessment of area protected. Looking beyond shelf areas, Spalding et al. (2008) point out that only 1.91 percent of waters within exclusive economic zone areas, and 0.717 percent of the...
The National Marine Sanctuary Program manages a system of sanctuaries and other managed areas around the country. The legal boundaries of these sanctuaries are defined within the Code of Federal Regulations, at 15 C.F.R. Part 922 and the subparts for each national marine sanctuary. The GIS compatible digital boundary files for each national marine sanctuary are representations of those legal boundaries and are based on the best available data. These files are available for public use at locations defined in this metadata record.
