An Ocean Acidification Monitoring Best Practice Training Workshop took place at the University of Auckland, New Zealand on 8-11 September 2015. The workshop was coordinated by Dr. Mary Sewell from the University of Auckland and Dry Todd Martz from the Scripps Research Institute, USA and benefited 12 researchers from New Zealand, Fiji and the Marshall Islands.

The aim of this workshop was to train participants to deploy pH sensors (Satlantic SeaFET), collect and analyze bottle samples for CO2 system properties, including pH, total alkalinity (AT), and total dissolved inorganic carbon (DIC), and combine results to generate high quality time series information. One of the main objectives of the workshop being allowing the participants to gain hands-on experience with SeaFET sensors, a total of four instruments were made available for the training.

At the beginning, the workshop discussed the SeaFET’s design history, advantages and limitations, data acquisition modes, deployment scenarios, precision, external validation and calibration, and data processing. Further, participants worked in smaller groups in order to gain familiarity with the procedures for managing the SeaFET, replace batteries, wet cap on electrodes, and other technicalities crucial to the correct deployment of the instrument. The SeaFETS were connected to personal computers and the SeaFETCom 1.2.4 software run in order to setup the logging parameters. Other parts of the training touched upon sensor calibration, experimental errors and offset curve derivation, and tried to replicate future ocean acidification scenarios.

The Ocean Acidification International Coordination Centre (OA-ICC) of the International Atomic Energy Agency (IAEA) supported the participation of the scientists from the Pacific islands and provided copies of the Guide to Best Practices for Ocean Acidification Research and Data Reporting, along with information packages on ocean acidification and the project’s activities.
