Florida Keys & Caribbean
The Florida Keys & Caribbean region is home to especially sensitive coral reef ecosystems and commercially important fisheries, which are all inexorably linked to coastal communities and economies. Research aims to better understand how vulnerable and important species and ecosystems respond to ocean acidification.
Understanding the ecological effects of ocean acidification
The Florida Keys and U.S. Caribbean rely on economically important fisheries, active tourism industries and fulfill important roles for coastal protection. Numerous marine life are sensitive to acidification and this further threatens biological and economic systems that are already degraded due to warming, disease, overfishing and eutrophication. These ecosystems’ heightened sensitivity to stress and their close relationship with carbonate chemistry serve to underscore the importance of ocean acidification in the region.
This region encompasses the Florida Keys and coastal waters of south Florida, as well as Puerto Rico, the U.S. Virgin Islands, and the surrounding areas between the Gulf of America and Atlantic Ocean. Processes driving acidification range from global carbon in surface waters to localized alteration of seawater chemistry by natural ecosystems and human activities. The Caribbean exhibits some of the highest carbonate mineral saturation states in the world, but also exhibits the most rapid rates of decline since pre-industrial times. Making holistic characterizations of these habitats is challenging, as fluctuations in seawater carbon dioxide are highly dynamic with variation ranging from decades to hours. Research in this area aims to address these challenges and prepare people to adapt to change.
Tracking progress of ocean acidification research in the Florida Keys and Caribbean

The research goals in the Florida Keys andCaribbean Region are to:
- Enhance the temporal and spatial resolution of ocean acidification (OA) monitoring to capture the ecologically-relevant variability of this dynamic region
- Monitor responses to OA on scales ranging from individuals to ecosystems, specifically targeting those that have been previously identified as susceptible to or threatened by OA
- Experimentally investigate the sensitivity and resilience of ecologically and economically important species, as well as the underlying molecular mechanisms that drive their differential responses to OA
- Develop interdisciplinary tools that integrate socioeconomic data with ecological outcomes.
The following charts represent the mid-point progress in implementing research actions that focus on the Florida Keys and Caribbean Region according to the NOAA Ocean, Coastal, and Great Lakes Acidification Research Plan.
NOAA invests in research and activities toward meeting goals that improve our ability to understand and predict environmental change, species and ecosystem to response to changing ocean chemistry, and the human impacts of these changes. The report card below summarizes progress over the past five years toward meeting these goals for the Florida Keys and Caribbean Region, measured by the number of major actions toward meeting this goal: good progress (4+ actions), some progress (1-3 actions) and no known progress.
Good overall progress
Some progress
No known progress
Environmental Change
There are 11 environmental change actions: three have good overall progress and seven have made some progress and one has no known progress.
Gaps still remain with biological and environmental monitoring. Studying environmental change in the Florida Keys and Caribbean focuses on improving the monitoring of chemical changes of the ocean across different locations and times. Including different marine species to ocean chemistry models can help predict how coral reefs are affected by ocean acidification.
Biological Sensisitivity
There are 10 biological sensitivity actions: four made some progress and six have no known progress.
Understanding how reef species respond to ocean acidification and other stresses is key for reef survival and management. More research is needed on how daily and seasonal ocean chemistry changes impact important species. Knowing how different genetic types react to OA will improve reef restoration efforts. Since ecosystems are linked and many species’ sensitivity is unknown, long-term studies of naturally high CO2 areas can reveal effects and adaptive capacity.
Human Dimensions
There are four human dimension actions: three have made some progress and one has no known progress.
Focusing solely on biological and chemical research and monitoring can lead to ineffective management of coastal resources. Linking ecosystem predictions with economic values helps us understand ocean acidification impacts for decision-makers. This includes the economic costs of reef damage and changes to fisheries. Future development of clear economic maps and socioeconomic indicators will aid effective communication of these risks and guide management and adaptation plans.
