AAS_4124_CEAMARC200708_BenthicStills

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

    Derived dataset from the forward facing still-images collected during the benthic trawls of the 2007/08 CEAMARC voyage of the Aurora Australis (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 latitude and longitude 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.

    Purpose

    The analysis of this dataset forms part of the journal article Jansen et al. (2018) Abundance and richness of key Antarctic seafloor fauna correlates with modelled food-availability. Nature Ecology and Evolution 2, 71-80.
