Definitions
A sea-surface temperature anomaly is the difference between a sea-surface temperature and a baseline temperature, which is typically calculated as the average of 30 years or more of recent temperature data. Annual sea-surface temperature anomalies are generally stable despite seasonal variations.

About this dataset
Measuring oceanic sea-surface temperature tells how fast the surface layer of the ocean is warming.
Purpose of collection
This indicator measures the state and trends for the temperature of the uppermost layers of surface water in oceanic and coastal regions around Aotearoa New Zealand using two satellite datasets.
Method of collection/Data provider
The provider used data from the Optimum Interpolation Sea Surface Temperature version 2.1 product (OISST) satellite between 1981 and 2023.
Monthly coastal sea-surface temperatures and anomalies between 2002 and 2022 are from the MODIS-Aqua satellite.
