Short summary
The marine reservoir age (MRA) is the difference between the 14C age of the ocean and that of the atmosphere at a given time. In geochronology, knowing the local MRA is important to derive accurate calibrated ages for 14C-dated marine material. However, MRA values for coastal West Africa are scarce. From the 14C dating of known-age bivalves from museum collections, we calculated MRA values and populated the MRA dataset for coastal West Africa over a latitudinal transect from 33°N to 15°S.
