Brief description

Refer to antFOCE report section 4.5.2 for deployment, sampling and analysis details.

https://data.aad.gov.au/metadata/records/AAS_4127_antFOCE_Project4127

The download file contains an Excel workbook with one data spreadsheet and one of notes relevant to the data. The data are the total number of each organism collected from artificial substrate units (plastic pot scourers) deployed in chambers or open plots during the antFOCE experiment (Data = Number of Individuals). Analysis methods are detailed in the Notes spreadsheet.

Background

The antFOCE experimental system was deployed in O’Brien Bay, approximately 5 kilometres south of Casey station, East Antarctica, in the austral summer of 2014/15. Surface and sub-surface (in water below the sea ice) infrastructure allowed controlled manipulation of seawater pH levels (reduced by 0.4 pH units below ambient) in 2 chambers placed on the sea floor over natural benthic communities. Two control chambers (no pH manipulation) and two open plots (no chambers, no pH manipulation) were also sampled to compare to the pH manipulated (acidified) treatment chambers.
