Description
The regional offset correction ΔR of Marine Reservoir Effect (MRE), crucial for correcting $^{14}$C ages calibration for marine influenced samples, was determined for Cuban Northwest coast. Fifteen different locations were studied by $^{14}$C dating of pre-bomb known-age marine shells specimens of bivalves and gastropods from the Felipe Poey Museum collection. The distribution of results indicates ΔR values from -46 ± 38 to 140 ± 52 $^{14}$C yr and a possible pattern related to the position along the coast and ocean dynamics. We present both mean values for each region and a general ΔR of 28 ± 13 $^{14}$C yr for the northwestern coast of Cuba.
