Abundances of benthic invertebrate species in the CEAMARC region 2007/08

Percent-cover estimates from 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. 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: (1)

• species/ morphotypes identified to the highest taxonomic resolution possible
• broader taxonomic classification (phylum/class)
• each species mobility, feeding-type and body-shape if possible
• average abundances in percent-cover at each site (2)
• 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
