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 Florida Keys and Caribbean Region include 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

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.

FRESCA – Florida Regional Ecosystem Stressors Collaborative Assessment: South Florida’s coastal and marine ecosystems provide critical ecosystem services and economic value to coastal communities. A variety of environmental stressors threaten these ecosystems, which can shift the structure and productivity of marine food webs. Led by Dr. Ian Enochs at AOML and Dr. Ana Palacio at University of Miami a team of nine scientists across seven institutions are investigating five interacting stressors: ocean acidification, hypoxia, harmful algal blooms, warming and eutrophication. This work improves our understanding of how these stressors impact ecosystems under present and future climate change scenarios. The project results will inform Everglades and Mission: Iconic Reefs restoration efforts and water quality and fisheries management. This work is funded by the National Centers for Coastal Ocean Science, the NOAA Climate Program Office, the NOAA Ocean Acidification Program and the Integrated Ocean Observing System, in collaboration with the Office of National Marine Sanctuaries.

In Puerto Rico, more than three million inhabitants rely on ocean and coastal resources for food, economic livelihoods and protection, but impacts from ocean acidification to coastal communities have not been assessed. To fill this gap, a regional vulnerability assessment in Puerto Rico assessed socioeconomic vulnerability through community interviews, identifying scientific trends and research gaps and holding a multi-disciplinary workshop to collect social and natural science perspectives and prioritize activities for a future regional vulnerability assessment. This project also created a multi-stakeholder network to form an initial framework for a new Caribbean Coastal Acidification Network, managed by CARICOOS.

Long-term declines of red king crab in Bristol Bay, Alaska may be partially attributed to ocean acidification conditions. These impacts may be partially responsible for the fishery closures during the 2021–2022 and 2022–2023 seasons. Researchers found that ocean acidification negatively impacts Alaskan crabs generally by changing physiological processes, decreasing growth, increasing death rates and reducing shell thickness. Funded by the Ocean Acidification Program, scientists at the Alaska Fisheries Science Center continue to investigate the responses of early life history stages and study the potential of various Alaska crabs to acclimate to changing conditions. Results will inform models that will use the parameters studied to predict the effects of future ocean acidification on the populations of red king crab in Bristol Bay as well as on the fisheries that depend on them. Fishery managers will better be able to anticipate and manage stocks if changing ocean chemistry affects stock productivity and thus the maximum sustainable yield.

Understanding seasonal changes in ocean acidification in Alaskan waters and the potential impacts to the multi-billion-dollar fishery sector is a main priority. Through work funded by NOAA’s Ocean Acidification Program, the Pacific Marine Environmental Laboratory developed a model capable of depicting past ocean chemistry conditions for the Bering Sea and is now testing the ability of this model to forecast future conditions. This model is being used to develop an ocean acidification indicator provided to fisheries managers in the annual NOAA Eastern Bering Sea Ecosystem Status Report.
