Antarctic benthic fauna data was collected from O'Brien Bay near Casey station during the austral summer of 2014/15. The dataset originates from the antFOCE experiment, which manipulated seawater pH in seafloor chambers to study ocean acidification effects. It was published by the Australian Antarctic Data Centre in March 2015.
Use Cases
- Analyze faunal recruitment and abundance from recruitment tile data under different pH treatments.
- Compare community composition metrics between acidified chambers, control chambers, and open plot samples.
- Model relationships between manipulated pH levels (a reduction of 0.4 units) and observed fauna on hard substrates like artificial substrate units.
- Investigate biofilm-associated fauna data collected from biofilm slides as part of the benthic community assessment.
Strengths
- Data is from a controlled, in-situ ocean acidification experiment with replicated treatment and control chambers.
- Includes comparisons across three distinct experimental conditions: acidified chambers, control chambers, and open plots.
Limitations
- Dataset is temporally limited to a single austral summer field season (2014/15).
- Sample size and geographic scope are constrained to one bay in East Antarctica.
- Specific row counts, column details, and file formats are unknown from available metadata.
Provenance
