Dataset: Reef community abundance data collected from SCUBA divers in the middle Florida Keys from June 2022 to July 2024

These data are annual summer census data for 30 reefs in the middle Florida Keys taken between the months of June and July each year. The survey is based on a permanent transect 50 m in length and 30 m in width. Divers survey substrate composition by taking 12 50 cm x 50 cm photographs at 10 m intervals on the left and right side of the main transect tape. Fish counts for butterflyfishes and parrotfishes and sea urchin counts are collected by two divers visually counting along each side of the main transect down and back. The counts are then averaged. Additional reef fish surveys are taken from a video filmed by diver swimming along the main transect at a rate of 50 m / 3 mins. Cryptofauna abundances are from a single Autonomous Reef Monitoring Structure (ARMS) located in the center point (25 m) of the main transect line. Abundance is the sum of the counts, richness is based on the number of observed operational taxonomic units, diversity is Simpson's Index of Diversity (1-D method). Rugosity is by chain and tape method (1- D/L). Temperature data (12 months prior to the annual June census (July 1 - June 30)  is average daily SST, average daily SST anomaly, average daily degree heating weeks (DHW), maximum SST, maximum SST anomaly, and maximum DHW taken from Coral Reef Watch NOAA Satellite data for the following pixels (https://pae-paha.pacioos.hawaii.edu/erddap/griddap/dhw_5km.graph).  See the supplemental file "dhw_5km_location_pixel_coordinates.csv" for a list of site names and corresponding pixel latitudes and longitudes.
