IMPORTANT USER ALERT (2 July 2024): This past weekend, a storage server at NOAA's Center for Satellite Applications and Research, which delivers the NOAA Coral Reef Watch data, suffered a hardware failure. The issue is being addressed, and we hope to have the NOAA Coral Reef Watch data back up and running as soon as possible. (1) The most recent data will be made available first; historical data may take time to be restored. (2) If you need specific data that are not yet available, please contact us at coralreefwatch@noaa.gov. (3) If you use code to pull data, please revise your code to use “…/socd/…” in lieu of “…/sod/…” in all relevant web addresses for all future needs. We apologize for any inconvenience this may cause.
