Carbon 14 and 39Ar data from the Weddell Sea are presented and discussed. Values of Δ 14C and 39Ar are low in the winter mixed layer (Δ 14C ≈ −90 to −125‰; 39Ar ≈ 85 % modern). These low values are consistent with the surface layer dynamics which is dominated by entrainment of relatively old water o...
