Reef fish abundance and size data collected by transect and stationary point count methods: a calibration to enable the use of long-term, fishery-independent data by fisheries and regional managers in the US Caribbean (NCEI Accession 0281207)

This project ensures that the existing data from previous fishery independent surveys can be combined with data collected under new methodology, ensuring preservation of long-time series reef fish datasets in the US Caribbean. Specifically, this archived dataset are the site level fish abundance and size observations collected simultaneously by one transect diver and a pair of stationary point count divers at survey sites in Puerto Rico and the U.S. Virgin Islands. These collection methods represent the pre- National Coral Reef Monitoring Program (NCRMP) belt-transect survey methodology and the currently used Reef Visual Census (RVC) survey methodology, respectively. More information about the methodologies can be found (Jeffrey 2019 & CRCP 2022). In the U.S. Caribbean, the National Coral Reef Monitoring Program began in 2012. Initially, the belt transect method was used for fish surveys, but then transitioned to the RVC method in all the U.S. Caribbean by 2016. This dataset is the field samples collected in order to properly calibrate belt transect data to RVC data.
