An Assessment of CO2 Storage and Sea‐Air Fluxes for the Atlantic Ocean and Mediterranean Sea Between 1985 and 2018
From 1985 to 2018, pCO2 products suggest a lower mean CO2 uptake (−0.36 ± 0.06 PgC yr−1) than ocean models (−0.47 ± 0.15 PgC yr−1) Since 2000, the CO2 uptake is increasing twice as fast in the pC...

A new study by GEOMAR and Plymouth Marine Laboratory shows that the exchange of gases between air and sea is not symmetric, and that the global ocean has taken up around 15 per cent more CO2 than suggested by conventional estimates.

Fig 1: (A) Schematic of the box model. Boundaries of the box model are selected Mθe surfaces at 15, 30, 45, and 60 Mθe values (1016 kg), which are shown as zonal and 2009 to 2018 averages. (B) Selected near-surface Mθe contours as 2009 to 2018 averages. Mθe is computed from 3-h MERRA-2 reanalysis. These Mθe bands are nearly fixed with season. Red triangles show the location of surface stations that are used in the Carbon Tracker 2019b 3D (three-dimensional) CO2 inversion product.

Figure 5Panel (a) shows the spatial distribution of the annual average air–sea CO2 exchange (FCO2, in mol C m−2 yr−1) and (b) seasonal FCO2 variability (expressed as the root mean square (RMS, in mol C m−2 yr−1)) calculated with the reconstructed coastal pCO2-product (ULB–SOM–FFN–coastalv2, 1982–2020 climatology). The latitudinal mean FCO2 distribution (red line) and its associated longitudinal variability (red shading) is presented in panel (c). This latter is compared with the FCO2 calculated with the ULB–SOM–FFN–coastalv1 pCO2-product (in green; Roobaert et al., 2019) and against a synthesis of 214 regional FCO2 estimations (blue dots; Dai et al., 2022). For consistency in the comparison in (c) we applied the same coastal delimitation as in Dai et al. (2022) and Roobaert et al. (2019) to the FCO2 ULB–SOM–FFN–coastalv2 product, i.e., we used the shelf break as the outer limit of the coastal domain (narrow coastal ocean). Panel (c) is also reconstructed based on an overlap period between the three products (1998–2020; except FCO2 ULB–SOM–FFN–coastalv1 which is limited to the 1998–2015 period).

New study by Dong et al. shows that #bubble-mediated #CO2 transfer favors invasion based on field evidence. They introduce an asymmetric #BulkFlux equation, suggesting that the global #ocean may absorb ~15% more #CO2 than previously estimated.

Figure 7Long-term trend G of surface pCO2 from the monthly mappings and the climatology construction (Eq. 1). Areas where the long-term trend is not significant are cross-hatched. In the southern Baltic Sea, a significant increase of +1.4 µatm yr−1 is obtained from the observations. Selected parts of the northern Baltic proper, the Åland Sea, and the Gulf of Finland give a similar increase of +1.5 µatm yr−1, while the western and eastern Gotland Basin show no significant long-term trend.

Recent advances in satellite observation-based data for studying the surface water marine carbonate system. a) Global assessments of the amount of gaseous CO2 (pCO2) can be mapped using satellite observations in conjunction with in situ databases to provide decadal-scale monthly data inputs to annual carbon assessments (i.e. Friedlingstein et al., 2021) (data from Gregor and Gruber, 2021); b) Regional assessments using satellite observation-based methods can quantify alkalinity and dissolved carbon flowing from the Amazon into the Atlantic (data from Land et al., 2019).

A positive flux denotes an outgassing from the ocean to atmosphere. In panel (a), AS, BoB, SEIO denote Arabian Sea, Bay of Bengal, and southeastern Indian Ocean respectively. Sumatra, Java, SS, LS, and TS represent Sumatra island, Java island, Lombok Strait, Sunda Strait, and Timor Sea respectively. Arrows in panel (c and d) depict the ocean circulation of climatological annual mean and interannual anomaly for 2015, derived from MOM6-COBALT. Data products are from MPI SOM-FFN and OS-ETHZ-GRaCER. The interannual anomaly is averaged between August 2015 and July 2016.
