AAS_4124_CEAMARC200708_BenthicStills_InvertebrateAbundances
All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description
Abundances of benthic invertebrate species in the CEAMARC region 2007/08 - 2018 update by Daniela Farias for GBIF/OBIS compliance.
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 latitude and longitude 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
Purpose
The analysis of this dataset forms part of the journal article Jansen et al. (2018) “Taxonomic resolution, functional traits, and the influence of species groupings on mapping Antarctic seafloor biodiversity” (Frontiers in Ecology and Evolution, 2018).
Quality
Australian Antarctic Data Centre note - 2018-07-03:
The original datasheet was reformatted to fit IPT Biodiversity.AQ standard. The new datasheet "ceamarc_0708_invertebrates.csv" provides the dataset ID, sites, decimal latitude and longitude, country, continent, occurrence, date of event, organism quantity (biomass). The taxonomical organisation is provided to the lowest taxonomical rank that could be determined, after matched in WoRMS (World Register of Marine Species).
