“…The conductivity sensor was calibrated by comparison with the in-situ conductivity of bottle samples taken during the upward profile with the rosette. CTD data processing and removal of typical non-linear effects in sensor responses was performed following Müller et al (1995). The salinity samples were analysed with a Guideline AUTOSAL salinometer with a accuracy better than 0.002 for single samples.…”

We show the distribution of nutrients, oxygen, total dissolved inorganic carbon (C T ) and total alkalinity (A T ) along three sections close to the Canary Islands, between 18ºW and the African coast during the Meteor 37/2 cruise (January 1997). From thermohaline properties of North Atlantic Central Water, Mediterranean Water, Antarctic Intermediate Water (AAIW) andNorth Atlantic Deep Water-a mixing model has been established that is based on the water mass description. It can explain most of the variability found in the distribution of the chemical variables, including the carbon system, and it is validated through the use of conservative chemical variables like 'NO'. From nutrients, oxygen, A T and C T , the chemical characterisation of the water masses was performed calculating the concentration of these variables in the previously defined end-members. The relative variation of nutrient concentrations, resulting from the regeneration of organic matter, was estimated. Close to the African shelf-break, a poleward undercurrent with an AAIW signal was observed only in the southern section (28.5ºN). From the chemical and thermohaline properties of the end-members a comparison with data from other oceanic regions was made in respect to conservative chemical variables ('NO'). In addition, from the residuals of the model, a north-south gradient in the ventilation pattern of water masses is observed.
