The conversion into calendar dates of radiocarbon ages of marine organisms collected on the coastal waters of the Canary Islands. The new Marine20 calibration curve
Recently, a new calibration curve for marine radiocarbon dates (Marine20) has been published. Since the modelling carried out for its setting up, as well as the database used, are different from those utilised for the previous curves (Marine04, Marine09, Marine13), it becomes necessary to calculate...

| Sumario: | Recently, a new calibration curve for marine radiocarbon dates (Marine20) has been published. Since the modelling carried out for its setting up, as well as the database used, are different from those utilised for the previous curves (Marine04, Marine09, Marine13), it becomes necessary to calculate new values of the marine reservoir effect (ΔR₂₀) for the oceanic region under study. This work precisely presents the reliable ΔR₂₀ values for the coastal waters of the Canary Islands, determined using two previously published databases consisting of conventional ¹⁴C dates of pairs of coeval samples that lived in different carbon reservoirs, namely in the marine and in the terrestrial biospheres. Users of the Marine20 curve are thus provided with the new and most reliable values so far determined for this North Atlantic region |
