Similarly, we may better understand how increased temperatures interact with local problems such as pollution to place our reefs at risk. Data are compared to better understand how well satellite data measure temperatures that the corals feel. Satellite sea surface temperatures are compared to long-term averages and annual maxima. Electronic communications notify sites around the world, even many of the most remote island locations. Scientists and divers watch for bleaching in the reef systems.
Feedback allows for improvements in the techniques.
Just as important as new technology, an increase in the coral reef observing network has improved our ability to note the appearance of widespread events as they happen. The Global Coral Reef Monitoring Network, Reef Check, and other global to local monitoring efforts launched since the start of the International Coral Reef Initiative have greatly increased our ability to observe and report bleaching events.
