IMOS - ANMN Acidification Moorings Maria Island Platform

The Maria Island acidification mooring is co-located with the Maria Island National Reference Station (NRSMAI) on the east coast of Tasmania. It was first deployed in April 2011.

The mooring's instruments measure surface CO2, temperature and salinity. The hydrochemistry sampling at the National Reference Stations will also provide total alkalinity data, as will future pH sensors on the moorings, allowing for a complete determination of the carbonate system and pH. Current instrumentation: Battelle Seaology pCO2 monitor, Aanderaa Oxygen Optode and Sea-bird Electronics, model SBE16plus V2 SEACAT.

The Acidification Moorings sub-facility is responsible for building an ocean carbon and acidification monitoring network for Australian waters. These moorings provide key observations to help us understand and address the problem of increasing ocean acidification.

玛丽亚岛酸化锚系（Maria Island acidification mooring）与塔斯马尼亚东海岸的玛丽亚岛国家参考站（NRSMAI）同址布设，该锚系于2011年4月首次部署。

该锚系搭载的仪器可测量表层二氧化碳、温度与盐度。国家参考站的水化学采样工作将提供总碱度数据，未来锚系上的pH传感器也将补充此类数据，由此可完整确定碳酸盐系统参数与pH值。当前搭载的仪器包括：Battelle Seaology型pCO₂监测仪、Aanderaa型溶解氧光学传感器（Oxygen Optode），以及Sea-bird Electronics公司生产的SBE16plus V2 SEACAT剖面仪。

酸化锚系子设施负责构建澳大利亚海域的海洋碳与酸化监测网络。此类锚系所获取的关键观测数据，有助于我们理解并应对日益加剧的海洋酸化问题。
