The carbon system is defined by four variables: pH, Total Alkalinity (AT), partial pressure of carbon dioxide (pCO2) and Total Inorganic Carbon (CT). The knowledge of two of these variables allows the calculation of the other two by means of a set of equations deduced from thermodynamic equilibrium. During the OVIDE 2004 cruise carried out between 5th June and 6th July on board the RN THALASSA pH and TA measurements were sampled fiom bottle depths at selected stations (Table 1) and analysed on board. Moreover, pCOz has been continuously detennined in surface waters along the vesse1 track. In this cruise, unlike OVIDE 2002, samples for CT were also taken, but will be analyzed at lab. CT is also calculated from pH and AT. In this report we resume the... |
