Density of adult and juvenile octocorals on shallow reefs in St. John, US Virgin Islands from 2010 (St. John LTREB project, VI Octocorals project)

Description

To evaluate the possibility that density-associated effects modulate octocoral abundance on a Caribbean coral reef, we tested the hypothesis that the density of octocoral recruits (colonies <= 4 cm tall) and adult colonies are positively associated on shallow reefs (<=14 m depth) in St. John, US Virgin Islands. Both life stages were censused for density at 8-10 sites along 7 km of shore in 2013 and 2014, and a correlative approach was used to evaluate the extent to which the densities were associated using sites as replicates.

Data Processing Description

BCO-DMO Processing Notes:

- original file: 'MetaData_KPJetal_JEMBE2015_STJ_Octocorals.xlsx'
- added conventional header with dataset name, PI name, version date, citation
- renamed parameters to BCO-DMO standard
- replaced spaces with underscores
- replaced blank cells with 'nd' (no data)
- reformatted data from columns to rows to conform with database practices
- added lat, lon, and depth columns
- sorted resulting flat file by year, taxon, site, stage
