Abstract

Intense rainfall from tropical cyclones can induce coastal acidification, a phenomenon exacerbated by climate change. This study examined carbonate chemistry in Galveston Bay, Texas, before and after Hurricane Harvey in 2017 and 2018. Findings reveal ecosystem-level acidification and calcium carbonate undersaturation following the storm, persisting for over three weeks due to prolonged reservoir releases. This acidification event contributed to high oyster mortality rates and potentially impeded reef recovery. The projected increase in tropical cyclone rainfall under climate change poses a significant threat to coastal calcifying ecosystems.
