Environmental Monitoring

Learn about Coral Bleaching

Weather conditions such as calm winds and clear sunny days can lead to an increase in sea temperatures and are generally associated with severe and/or extensive coral bleaching events. Monitoring seasonal climate predictions and local weather forecasts helps identify periods of light winds and decreased cloud cover, which can lead to heightened coral stress.

NOAA's Coral Reef Watch program (CRW) plays a pivotal role in predicting and monitoring sea surface temperatures remotely. Leveraging near real-time satellite products and modeled Outlook predictions, NOAA CRW has successfully tracked and predicted major coral bleaching events globally since 1997.

NOAA CRW products support conservation, restoration, and resilience-based research and management projects that aim to protect and/or restore coral reefs in a rapidly warming world. In times of low or no heat stress, CRW products can aid in identifying locations to implement conservation and restoration initiatives. Additionally, NOAA CRW’s work informs many national and international assessments of coral reef conditions.

In southeast Florida, the SEAFAN BleachWatch program utilizes NOAA CRW products, including CRW's satellite-based Regional Virtual Station for Southeast Florida and single-pixel Virtual Stations for Florida, to: predict and monitor changes in localized thermal stress, prepare and prioritize resources for coral bleaching events that impact reef health and function; communicate, quickly and broadly to local stakeholders; implement timely, protective responses and adaptation actions and assess when specific reefs are vulnerable or resilient increasing thermal stress.

Current Condition Reports

Reports are generated throughout the summer season when conditions are more conducive to coral bleaching. These reports provide an overview of coral conditions throughout southeast Florida and include a summary of environmental monitoring and field reports by the BleachWatch Observer Network. Reports will be posted here when available.
