New tool to calculate thermal stress, predict bleaching

Learn to calculate thermal stress, predict bleaching  

NOAA Coral watch programNOAA's Coral Reef Watch program has released a training module that teaches users how to predict coral bleaching from satellite sea surface temperature (SST) data.

The interactive training module has been developed by the Remote Sensing Working Group of the CRTR Program in collaboration with UNESCO’s long-running Bilko remote-sensing distance-learning project. Bilko is available to registered users absolutely free and is used by thousands of students of remote sensing worldwide.

The step-by-step lesson follows the operational Coral Reef Watch methodology, so that users will gain in-depth knowledge of how the NOAA data are produced. They will learn how to calculate a long-term average temperature from satellite data, and identify a specialized anomaly (HotSpot) that shows areas where corals are under stress and likely to be bleaching.

ScreenshotTo demonstrate how these satellite data are used in the real world, the lesson ends with an activity based on a real bleaching event in the Caribbean Sea in 2005. Users can interpret satellite data to predict coral bleaching, then compare their predictions with real-life bleaching data.
