Sediment Fauna data from the antFOCE (Antarctic Free Ocean Carbon Enrichment) experiment at Casey Station

Metadata record AAS_4127_antFOCE_SedimentFauna contains all data sets relating to the fauna sampled from marine sediments during the antFOCE experiment, including macrofauna, meiofauna, diatoms, microbes, as well as DNA sequencing conducted on some of these groups and the results of a sediment bioturbation study.

Refer to antFOCE report section 4.4 for deployment, sampling and on-station analysis details.

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.

Details of the antFOCE experiment can be found in the report – "antFOCE 2014/15 – Experimental System, Deployment, Sampling and Analysis". This report and a diagram indicating how the various antFOCE data sets relate to each other are available at:
