This dataset was first added to MfE Data Service on 18 Aug 2022.

Adapted by Ministry for the Environment and Stats NZ to provide for environmental reporting transparency. Dataset used to develop the "Ocean acidification" indicator (available at  www.stats.govt.nz/indicators/ocean-acidification).

This data set measures the pH at selected coastal sites via the New Zealand Ocean Acidification Observing Network (NZOA-ON) from 2015 to 2021.

Ocean acidification describes the long-term decrease in the pH of our oceans and coastal waters. This indicator measures:

  • pH at selected coastal sites (New Zealand Ocean Acidification Observing Network, NZOA-ON) from 2015 to 2021.

Adapted by Ministry for the Environment and Stats NZ to provide for environmental reporting transparency. Dataset used to develop the "Ocean acidification" indicator (available at  www.stats.govt.nz/indicators/ocean-acidification).

This data set measures the change in pH in subantarctic surface waters at a station east of Otago from 1998 to 2020.

Ocean acidification describes the long-term decrease in the pH of our oceans and coastal waters. This indicator measures:

  • change in pH, acidity and pCO2 (a measure of dissolved carbon dioxide) in New Zealand’s subantarctic surface waters (Munida Transect) from 1998 to 2020.

This dataset was first added to MfE Data Service on 16 Oct 2019.

These data estimate the occurence of extreme wave events in coastal and oceanic waters for 2012, particularly for wave events where significant wave height exceeds a threshold of 8 metres and for a period of at least 12 hours. Significant wave height is defined as four times the square root of the variance of sea surface elevation due to wave motion.
