Coral bleaching data from BleachWatch in the Florida Keys National Marine Sanctuary from 2024-05-28 to 2024-10-15 (NCEI Accession 0311613)

As the occurence and severity of coral bleaching has increased in the Florida Keys National Marine Sanctuary (FKNMS) since the 1980’s, The U.S. National Oceanic and Atmospheric Administration (NOAA) and other scientists have developed remote sensing products and a network of environmental monitoring stations in order to try to more accurately predict coral bleaching in the Florida Keys. However, although remote sensing and in-situ data collection can provide an indication of when environmental conditions are ideal for the onset of coral bleaching, the actual onset of bleaching can be a gradual process, and effects can vary over an area as large as the FKNMS. In order to accurately assess the initial affects of bleaching events, and to assess coral condition during and after bleaching events, the Florida Keys BleachWatch program coordinates a large network of trained observers to provide regular reports of actual coral conditions on the reefs. Each BleachWatch observer receives a packet containing information on the project and FAQ’s on coral bleaching, report forms complete with detailed instructions, and an underwater visual aid. The report form has been designed to minimize the effort needed to make observations and report on conditions, and the underwater visual aids are designed to minimize gear for the diver to carry yet be easily accessible and available when needed to help make mental notes on coral condition throughout the dive. The underwater visual aid provides a summary of the important information needed from the monitoring form such as environmental conditions as well as images to help determine percent of bleached live coral cover and major growth types for ease of coral identification. After exiting the water, observers simply enter these and any other notable observations on the report form provided. Observers are asked to report as regularly as possible, and are made to understand that observations of no bleaching present are equally as important. By interpreting observations of coral condition from various areas within a geographic zone of concern during potential bleaching events, additional insight can be gained toward determining natural resilience, both for habitat types, geographical location, and species of coral. This information will allow researchers to further develop the accuracy of available coral bleaching early warning products and assist resource managers to better communicate the condition of the reefs as potential bleaching events occur, as well as potentially integrating the information into existing management plans.
