Metadata for study of the efecct of antibiotic treatment on Coral communities in the British Virgin Islands There are three CSV files coral_raw_data "Raw data sheet, each row is one coral colony" coral_species_codes List of coral species codes. Each coral species is identified using 4-letter code disease_codes List of coral disease codes and codes for other types of lesion and coral damage coral_raw_data - variable descriptions Some variables are inherited from a previous study and not used in the current study (these variable names are highlighted in grey) year excel_date date in excel format depth_m sctld_treatment Was the site treated with antiobiotics for SCTLD (yes or no) site_pair Sites were surveyed in pairs (one treated and one an untreated reference). This variable lists the pairs site_code Name of each site surveyed transect_no Each 30 m transects surveyed within a site was numbered transect_length Usually 30 m except if SCUBA constraints meant stopping before 30 m was surveyed (measured in m) m_surveyed_site Total # metres of transect tape surveyed per site #_transect_site Total # transects surveyed per site strong_denom 1 / m_surveyed_site (is the denominator for the Strong formula to calculates coral density) * 100 to make the unit colonies per 100 m2 (so it is a larger number nd easier to interpret) fixed_transect "For Guana Island sites only, was this a fixed transects (same location sampled each year, yes or no)" dist_along_tape "For some Guana Island sites only, location of the coral along the 30 m tape" line "For 2009 survey only, line = basic line intecepot survey, belt = additional 30 x 1 m survey for coral disease, codled 0 or 1)" belt "For 2009 survey only, line = basic line intecepot survey, belt = additional 30 x 1 m survey for coral disease, codled 0 or 1)" coral_code 4-letter coral species code SCTLD_suscept Code for susceptibility of the coral species to SCTLD (see coral_species_codes sheet) max_l_cm length of coral colony in cm (parrallel to tape) max_w_cm width of coral colony in cm (orthogonal to tape) max_h_cm height of coral colony in cm Strong_num 1/width in m (numerator of formula for calculation of coral colony density using Strong method) Geom_shape Colonies were approximated as hemispheres or cylinders (see coral_species_codes sheet) sa_tot total surface area of the colony (sq. cm) sa_live total surface area of live tissue in the colony (sq. cm) perc_ld "% of colony surface area that was ""long dead"" (defined in the paper)" perc_rd "% of colony surface area that was ""recently dead"" (defined in the paper)" perc_dead % of colony surface area that was dead (rd plus ld) sa_dead total surface area of the colony that was dead (sq. cm) rd "2009 data only, code for recently dead (0 = no, 1 = yes)" sa_rd total surface area of the colony that was recently dead (sq. cm) ld "2009 data only, code for long dead (0 = no, 1 = yes)" sa_ld "2009 data only, surface area of the colony that was rd (sq. cm)" notes dis_code Code for specific categories of disease and other sources of colony damage (see disease codes sheet) dis_category Code for broad categories of disease and other sources of colony damage (see disease codes sheet) white coded 1 for any coral with this disease category and 0 otherwise nonwite coded 1 for any coral with this disease category and 0 otherwise notdisease coded 1 for any coral with this disease category and 0 otherwise per_dis1 percent of the colony that was diseased per_white percent of the colony that was diseased with disease_category white per_nonwhite percent of the colony that was diseased with disease_category nonwhite per_notdisease percent of the colony that was diseased with disease_category notdisease sa_dis1 total surface area of the colony that was diseased (sq. cm) no_lesion1 "2009 study only, # diesease lesions" dis2 "2009 study only, if there were multiple disease types on a colony they were coded here" per_dis2 "2009 study only, if there were multiple disease types on a colony they were coded here" sa_dis2 "2009 study only, if there were multiple disease types on a colony they were coded here" coral_species_codes - variable descriptions in_sctld_study was the species ercorded in the 2021 study (yes or no) SCTLD_susceptibility "high, medium, low-uncertain, or none (Suceptibility is based on Bruckner's NOAA ID guide and agrra.org, https://www.agrra.org/coral-disease-identification/)" Sp_code "4-letter species code (usually 1st 2 letters of genus name and 1st 2 letters of species name, but some exceptions)" Geom_shape Gemometric shape used to estimate colony surface area (hemisphere or cylinder) Species_genus "Note that some species and genus names may be outdated, check current names before public sharing" Genus species Notes disease code - variable descriptions dis_code category of damage based on vidual signs dis_category "broad categories of disease used for analysis because SCTLD cannot be identifieds reliably on individual colonies (white = SCTLD and other raipd loss white syndromes, non-white = othe diseases, not disease = bleaching and other causes of tissue loss)" disease_name Notes
