Observational analysis reveals declining anthropogenic carbon dioxide storage rates in North Atlantic waters, indicating a weakening ocean carbon sink.

Key Points

To estimate the accumulation and storage rates of anthropogenic carbon dioxide across key North Atlantic water masses between 1981 and 2006.
Analyzed an inorganic carbon system database compiled from 13 research cruises conducted over 25 years (1981–2006).
Applied the φC°T method to quantify anthropogenic CO2 concentrations across distinct vertical layers and sub-basins in the North Atlantic.
North Atlantic Central Water exhibited the highest annual accumulation rate (1.13 ± 0.14 μmol kg⁻¹ yr⁻¹) in the Iberian Basin, decreasing along the upper overturning circulation limb to 0.68 ± 0.06 μmol kg⁻¹ yr⁻¹ in the Irminger Basin.
Anthropogenic CO2 storage rates in the subpolar gyre were ~48% higher during the high North Atlantic Oscillation phase of the early 1990s compared to the 1997–2006 low-phase period.
Deep water layers demonstrated reduced storage rates compared to surface layers, with alterations in deep-water ventilation directly driving the overall weakening of the carbon sink.
