Abstract

Radiocarbon analyses, stable isotopic measurements and extensive field observations were made of coral reefs off the Pacific coast of Costa Rica and Panama. Several lines of evidence are presented in the study described which indicate that the seasonally upwelling Papagayo area in NW Costa Rica is today less conductive to reef development than the nonupwelling waters of SE Costa Rica and the Gulf of Chiriqui, Panama, and the seasonally upwelling waters of the Gulf of Panama. Data examined here include reef size (area and thickness), live coral cover and diversity, maximum depth of framework construction, coral colony size distributions, growth rates, intensity of bioerosion, frequency of growth discontinuities, carbon-14 dating and stable isotope analyses of coral skeletons.
