Derived dataset from the forward facing still-images collected during the benthic trawls of the 2007/08 CEAMARC voyage (raw data-set here: https://data.aad.gov.au/metadata/records/CEAMARC_CASO_200708_V3_IMAGES). All fauna in the bottom third of each image was scored to the lowest taxonomic resolution possible, and operational taxonomic units (OTUs) were aggregated by feeding type afterwards. The images originate from 32 transects, but were split by their lon-lat-position within a spatial grid of environmental variables into 41 sites. This dataset contains: - the mean longitude of all images aggregated per site. - the mean latitude of all images aggregated per site. - the number of images scored per site - the aggregated abundances (given in %-cover) for three main benthic groups (SF=Suspension Feeder, DF=Deposit Feeder, PR=Predator). - number of OTUs observed per benthic group per site. - the total number of OTUs observed per site.
