Methods

Sites are at least 250 m apart where possible. Within each site. five 50 m transects (paths along which seafloor organisms will be studied) are laid along the reef slope parallel to the reef crest at about 6-9 m depth. Transects are marked with a star picket at each end and with lengths of reinforcing rod at 10 m intervals for full methods see here - http://www.aims.gov.au/docs/research/monitoring/reef/sampling-methods.html Unit of abundance = Occurrence, Unit of biomass = NA
