AAS_4633_BEAUT_Marine_benthic_CaseyDavis_Photoquadrats

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

    A data set comprising benthic community data from 2263 photoquadrats from Casey and Davis areas between 1997 and 2022. Photos were annotated to record % cover of biota, substrate type, and counts of some invertebrate taxa, mainly larger or solitary species and mobile species. Photos were taken either by divers using photoquadrat frames, or by an ROV with bottom mounted cameras.

    Purpose

    Benthic community composition including % cover, substrata type, and counts of some species (generally larger mobile or sessile individuals) obtained from photoquadrats. These were taken to assess biodiversity, community composition, spatial variation and to establish baselines for future comparison. Some of the sampling designs were focused on local human impacts (sewage outfalls, waste disposal sites, wharf areas) in comparison to controls sites.

    Quality

    Image quality varies depending on the type of camera system used (film, early low resolution digital, more recent higher resolution digital), water visibility conditions and light availability.
    Taxonomic identification often limited to morphospecies based on visual appearance in photos. Some taxa were reliably identified to species level.
