フロリダ湾
Another threat to the Florida Reef is the ongoing rise in sea level. The sea level has risen almost six inches (15 cm) at Key West since 1913, and one foot (30 cm) since 1850. This rise in sea level increases the volume of water in Florida Bay significantly, and increases the exchange of water between the Bay and the water over the reefs. The lower salinity, higher turbidity and more variable temperature of the water from Florida Bay adversely affects the reefs. A continued rise in sea level would likely intensify the effect.
