Task Team on Coral Heat Stress User SST Requirements

The health and continued viability of coral reefs throughout the world is in danger due to rising sea surface temperature (SST) as a result of climate change. Satellite-derived SST is therefore an important tool for researching the effects of and monitoring coral stress caused by anomalous SST. SST-based anomaly products that have been designed specifically for corals, such as those produced by the NOAA Coral Reef Watch (CRW) program are key to understanding and monitoring the effects of SST anomalies on coral health.


User Requirements Document

At G-XX (Frascati, Italy. 2019) the Science Team (ST) asked the Coral Heat Stress User Requirements Task Team to make recommendations on satellite SST requirements for use by coral scientists, users and coral reef managers. In 2020 the Task Team (TT) reported its findings to the ST at G-XXI and published a report “Coral Heat Stress User SST Requirements”.

Updates to the User Requirements Document

The TT is updating the GHRSST Coral Heat Stress Task Team (TT) user requirements document to include:

  • requirements for other uses of SST other than the quantification of heat stress;
  • an update to the current set of requirements to take account of evolving coral knowledge, e.g. recent work points to the need for an understanding of the entire diurnal cycle in and around a coral reef.

The updated report will be presented at the next Annual Science Team Meeting in 2021.
