Consistency of cruise data of the CARINA database in the Atlantic sector of the Southern Ocean 5
Hoppema, M.; Velo, A.; Van Heuven, S.; Tanhua, T.; Key, R. M.; Lin, X.; Bakker, D. C. E.; Perez, F. F.; Ríos, A. F.; Lo Monaco, C.; Sabine, C. L.; Álvarez, M.; Bellerby, R. G. J..
Initially a North Atlantic project, the CARINA carbon synthesis was extended to include the Southern Ocean. Carbon and relevant hydrographic and geochemical ancillary data from cruises all across the Arctic Mediterranean Seas, Atlantic and Southern Ocean were released to the public and merged into a new database as part of the CARINA synthesis effort. Of a total of 188 cruises, 37 cruises are part of the Southern Ocean, including 11 from the Atlantic sector. The variables from all Southern Ocean cruises, including dissolved inorganic carbon (TCO2), total alkalinity, oxygen, nitrate, phosphate and silicate, were examined for cruiseto- cruise consistency in one collective effort. Seawater pH and chlorofluorocarbons (CFCs) are also part of the database, but...

Temporal variability of the anthropogenic CO2 storage in the Irminger Sea 5
Perez, F. F.; Vazquez-rodriguez, M.; Louarn, E.; Padin, X. A.; Mercier, Herle; Rios, A. F..
The anthropogenic CO2 (C-ant) estimates from cruises spanning more than two decades (1981-2006) in the Irminger Sea area of the North Atlantic Subpolar Gyre reveal a large variability in the C-ant storage rates. During the early 1990's, the C-ant storage rates (2.3 +/- 0.6 mol C m(-2) yr(-1)) doubled the average rate for 1981-2006 (1.1 +/- 0.1 mol C m(-2) yr(-1)), whilst a remarkable drop to almost half that average followed from 1997 onwards. The C-ant storage evolution runs parallel to chlorofluorocarbon-12 inventories and is in good agreement with C-ant uptake rates of increase calculated from sea surface pCO(2) measurements. The contribution of the Labrador Seawater to the total inventory of C-ant in the Irminger basin dropped from 66% in the early...
