Shifts in coral reef biogeochemistry and resulting acidification linked to offshore productivity

Ocean acidification is hypothesized to have a negative impact on coral reef ecosystems, but to understand future potential impacts it is necessary to understand the natural variability and controls of coral reef biogeochemistry. Here we present a 5-y study from the Bermuda coral reef platform that d...

Description
Summary:Ocean acidification is hypothesized to have a negative impact on coral reef ecosystems, but to understand future potential impacts it is necessary to understand the natural variability and controls of coral reef biogeochemistry. Here we present a 5-y study from the Bermuda coral reef platform that demonstrates how rapid interannual acidification events on the local reef scale are driven by shifts in reef biogeochemical processes toward increasing net calcification and net respiration. These biogeochemical shifts are possibly linked to offshore productivity that ultimately may be controlled by large-scale climatological and oceanographic processes.
