Summary
Coral reefs are some of the most biologically rich and economically valuable ecosystems in the world. They provide food, fishing, and recreation opportunities for millions of people, protect coastlines from storms, and shelter thousands of plant and animal species. However, climate change is contributing to the degradation of coral reefs in two significant ways: warming temperature and increasing acidification of ocean waters. Scientists are actively working to gather more specific information about how these factors will impact coral reef ecosystems. The purpose of this study was to identify differences in climate vulnerability among three important reef-building coral species in the Florida Keys. Researchers used coral cores to [...]
Summary
Coral reefs are some of the most biologically rich and economically valuable ecosystems in the world. They provide food, fishing, and recreation opportunities for millions of people, protect coastlines from storms, and shelter thousands of plant and animal species. However, climate change is contributing to the degradation of coral reefs in two significant ways: warming temperature and increasing acidification of ocean waters. Scientists are actively working to gather more specific information about how these factors will impact coral reef ecosystems.
The purpose of this study was to identify differences in climate vulnerability among three important reef-building coral species in the Florida Keys. Researchers used coral cores to investigate the effects of temperature and decreasing ocean pH on coral growth over the last 150 years. Such information is useful for resource management decision-making regarding reef restoration and species protection policies. It also establishes a baseline for coral growth rates that can be referenced as ocean conditions continue to change.
Two significant contributing factors to the degradation of coral reef ecosystems are increasing ocean surface temperatures and decreasing ocean acidification. Both factors are related to anthropogenic disturbances of the global carbon cycle. However, there are too few datasets at this time to make educated predictions on the precise impact of these factors. This study aimed to identify differences in climate vulnerability among three important reef-building coral species, and subsequently to inform resource management decisions regarding reef restoration and species protection policies. Project goals included a study addressing long-term variability in ocean temperature and acidification and the corresponding response of coral reef development. This data will be used as important baseline information as ocean conditions continue to change.
