Marine Radiocarbon Reservoir Effect of Coastal Waters Off Cape Verde Archipelago

Quantification of the marine radiocarbon reservoir effect (ΔR) is essential in order to calibrate conventional 14 C dates from marine shell samples with reliability. ΔR also provides information concerning the intensity of coastal upwelling in marine regions influenced by this phenomenon. 14 C ages of closely associated marine samples (mollusk shells) and terrestrial samples (goat bones) from São Vicente Island, Cape Verde Archipelago, permitted the first calculation of the marine 14 C reservoir effect in this region. A ΔR weighted mean value of 70 ± 70 14 C yr was obtained. This value is in accordance with the previously published oceanographic conditions of the region indicating the existence of a seasonal active upwelling regime
