New Zealand's Environment Reporting Series: The Ministry for the Environment and Statistics New Zealand
Ocean acidification is the long-term decrease in the pH of our coastal waters and oceans. This indicator measures the change in pH in subantarctic surface waters at a station east of Otago from 1998 to 2017, and also the pH at selected coastal sites via the New Zealand Ocean Acidification Observing Network (NZOA-ON) from 2015 to 2017.
More information on this dataset and how it relates to our environmental reporting indicators and topics can be found in the attached data quality pdf.
