Abstract
Radiocarbon measurements on a 109-year-old (1868-1977) core ofMontastrea annulariscoral from Glover Reef, Belize, in the Gulf of Honduras, reveal uptake of fossil fuel CO2and bomb14C by surface ocean waters. The history of Δ14C values revealed by this Belize growth agree remarkably well with results for coral growth from the Florida Straits. It is concluded that these corals are reliable recorders of14C concentrations of dissolved inorganic carbon (DIOC) in surface waters representative of the Gulf Stream.Keywords
