The Cant variability in the water masses is evaluated from the comparison of two hydrographic sections along 7.5°N carried out in 1993 and 2010. During both cruises, high Cant concentrations are detected in the upper layers, with values decreasing progressively towards the deep layers. Overall, the Cant concentrations increase from 1993 to 2010, with a large increment in the upper North Atlantic Deep Water layer of about 0.18 ± 0.03 μmol kg−1 y−1. In 2010, the Cant inventory along the whole section amounts to 58.9 ± 2.2 and 45.1 ± 2.0 mol m−2 using CO2 and CFC based methods, respectively, with most Cant accumulating in the western basin.

Below ∼1000 m, these rates follow the pace expected from a progressive increase of Cant at steady state; above ∼1000 m, Cant increases faster, mainly due to the retreat of the Antarctic Intermediate Waters This work was funded by the 7th Framework Programme (EU FP7 CARBOCHANGE, under grand agreement no. 264879) and by the Spanish Ministry of Economy and Competitiveness through Projects GHGMOC (CTM2009-07574-E), MOC2 (CTM2008-06438-C02-01/MAR) and ESCLAT (CTM2009-07405-E/MAR) and by the Deutsche Forschungsgemeinschaft (DFG) (M.
