Environmental data from the antFOCE (Antarctic Free Ocean Carbon Enrichment) experiment at Casey Station
Listed in NASA Earthdata CMR
Metadata record AAS_4127_antFOCE_EnvironmentalData contains seafloor Ambient Light and ambient Seawater Temperature data sets collected at the antFOCE site during the experiment.
Description
Ambient Light data was collected using Photosynthetically Active Radiation sensors (Odyssey Dataflow 392 photo diode light meters) distributed around the antFOCE site as well as several inside the experimental chambers and open plots. Seawater Temperature data were collected using Onset Hoboware Tidbit v2 (UTBI-001) temperature loggers attached to the outside of various pieces of the underwater experimental infrastructure across the antFOCE site.

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