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...
