antFOCE Hard Substrate Fauna data sets

Metadata record AAS_4127_antFOCE_HardSubstrateFauna contains all data sets relating to the fauna sampled from hard substrates during the antFOCE experiment, including recruitment tiles, artificial substrate units and biofilm slides. Refer to antFOCE report section 4.5 for deployment, sampling and on-station analysis details. https://data.aad.gov.au/metadata/records/AAS_4127_antFOCE_Project4127Background 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:https://data.aad.gov.au/metadata/records/AAS_4127_antFOCE_Project4127元数据记录AAS_4127_antFOCE_HardSubstrateFauna收录了antFOCE实验期间从硬质基底采集的全部动物群数据集，涵盖附着招募贴片（recruitment tiles）、人工基底单元（artificial substrate units）及生物膜载片（biofilm slides）。请参阅antFOCE报告第4.5节以了解部署、采样及现场分析的详细信息。相关链接：https://data.aad.gov.au/metadata/records/AAS_4127_antFOCE_Project4127Background antFOCE实验系统于2014/2015年南极夏季部署在东南极洲凯西站以南约5公里的奥布莱恩湾（O’Brien Bay）。该系统的海面及冰下（海冰下方水域）基础设施可对放置于海底自然底栖群落上方的2个实验舱内的海水pH水平实施可控调控，将pH值降至较环境水平低0.4个单位。此外还设置了2个对照舱（不进行pH调控）与2个开放样区（无舱体、不开展pH调控），用于与酸化处理的实验舱进行对照比较。 有关antFOCE实验的详细细节可查阅报告《antFOCE 2014/15 – Experimental System, Deployment, Sampling and Analysis》。该报告及展示各antFOCE数据集相互关联关系的示意图可通过以下链接获取：https://data.aad.gov.au/metadata/records/AAS_4127_antFOCE_Project4127
