Resumen: During the cruise F/S Poseidon 212/3 (September 30-October 8, 1995) determination of carbon system variables was carried out over the section of La Palma-La Graciosa and at the ESTOC station in the Canary Island area. Total alkalinity and pH in the total scale at 25 degreesC were determined at 24 stations from surface to bottom. In this area, the presence of different water masses can be traced by the carbon system variables. NACW is defined by a strong gradient of A(T) and pH from 150 to 750 m. MW is characterised by high values of A(T) and pH between 1000 to 1200 in and AAIW signals are found at around 900 in in the strait between Gran Canaria and Fuerteventura with low A(T), low pH and a maximum of fCO(2). Assuming an atmospheric mean value of fCO(2) of 360 mu atm and an average surface value of 393 +/-7 mu atm, we can conclude that during this cruise this oceanic area tends to release CO2 into the atmosphere, acting as a weak source with a carbon flux towards the atmosphere of +8.0 +/-1.8 mmol.m(-2)d(-1). The saturation levels in the Canary Island area have been found to be higher than 3600 m for calcite and 2700 in for aragonite. The inorganic carbon/organic carbon ratio (IC/OC) varies from 0.07 at 300 m to 0.5 at 3000 m. The IC/OC ratio shows that about a 34% increase in the C-T of the deep water is contributed by the inorganic CaCO3 dissolution. The IC at 300 in is around 7 mu mol kg(-1), increasing with depth to 37.5 mu mol kg(-1) at 3700 m.
