Along with the worldwide data, we also focus in on some representative coral reef locations around the world. We call these "Virtual Stations": it is like having a temperature sensor in the water next to a reef, but it is completely based on satellite remote sensing measurements. Users can access time-series graphs and data for each of the Stations. To be more quickly informed you can also sign up for free automated e-mail alerts, which will warn you if corals in those areas are at risk for bleaching. All of these products are updated twice a week.

These experimental sites are open for comment, and the satellite data will be validated against in situ data where available. The new experimental sites complement the existing 24 operational Virtual Station sites, which have been running consistently since 2000.
