The technique for small volume oceanic AMS 14C measurement is described. The procedure includes sampling, CO2 extraction from the water samples, target preparation and measurement at the ETH/SIN AMS facility. AMS 14C data from a station in the southern Weddell Sea with an accuracy of ± 5‰ are presented. The data are in good agreement with large volume 14C measurements done by conventional low-level counting techniques with an accuracy of ± 2‰.
