bottom waters of the Weddell Sea, reveal a steady CO 2 increase of anthropogenic origin, as surface water charged with anthropogenic CO 2 is a major component in the formation of WSBW (Van Heuven et al [...] al. 2011). The findings reflect the deep-sea sequestration of anthropogenic CO 2 , thus contributing to diminishing the burden of excess CO 2 in the atmosphere. The largest increase of CO 2 is found in [...] in the surface layer (Van Heuven et al. 2014). Here, uptake of excess CO 2 , i.e. anthropogenic CO 2 , from the atmosphere has obviously occurred. Somewhat surprisingly, steady state tracer oxygen shows
