IMOS - ANMN Acidification Moorings Kangaroo Island Platform

The Kangaroo Island acidification mooring is co-located with the Kangaroo Island National Reference Station (NRSKAI) in South Australia. It was first deployed in February 2012, removed in June 2013 and redeployed in May 2014.

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: Battele 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.
