Sampling instrument: | Niskin Bottles |
Detailed sampling and analyzing information: | For the determination of alkalinity and total inorganic carbon, seawater samples were collected, at all stations and depths, into washed 500 ml borosilicate glass bottles, according to standard operational protocol. A small headspace (< 1 %) was adjusted to prevent pressure build-up and loss of CO2 during storage. Few drops of a saturated solution of HgCl2 were added to the samples in order to avoid any biological activity. Then, the samples were stored in the dark at constant temperature (~ 4 ºC) until their analysis on shore (IMAGES laboratory, Perpignan, France). The measurement of these two parameters was performed simultaneously by potentiometric acid titration using a closed cell. The principle and procedure of measurements, as well as a complete description of the system used to perform accurate analysis can be found in DOE (1994). The precision of alkalinity and total inorganic carbon analysis was determined to be ± 2 μmol kg-1 for alkalinity and ± 4 μmol kg-1 for total inorganic carbon, by titration of 261 samples, collected at the same conditions of temperature and S, from Banyuls Sur Mer, South France. The accuracy of alkalinity and total inorganic carbon measurements was determined to be ± 1 μmol kg-1 for alkalinity and ± 4 μmol kg-1 for total inorganic carbon by analyzing a total of 26 bottles of three different batches of Certified Reference Material (Andrew Dickson, CA, USA, batches 85, 86 and 128). |
