Using high-quality data
for the CO2-system and related properties obtained 10-year apart, we
estimated decadal increases of anthropogenic CO2 along the A10
section of the World Ocean Circulation Experiment (WOCE) Hydrographic Program
(WHP). Increases of anthropogenic CO2 were found down to an
isopycnal surface of 27.3σθ (approx. 1000 dbar). In the
sub-Antarctic Mode Water (SAMW), the increase was 6.9 ± 2.0 μmol kg-1
on average, while in the Antarctic Intermediate Water (AAIW), it was 4.2 ± 1.9 μmol
kg-1. The increase in SAMW was larger in the west than that in the
east of the section. No significant increases were detected in North Atlantic
Deep Water (NADW) and Antarctic Bottom Water (AABW).
