The measurements of CO2 partial pressure were performed according to the principle described by Copin-Montégut (1985).

Data of pCO2 and physical properties of surface waters are presented in form of daily files, beginning the 7^th of September to 4^th October 1999. Data have been acquired each minute, so length of file is 1440 rows. Files are named as pco_ddmm.dat (28 files at all).

Numbers columns of each file are:

Col. #1: time in Julian days since the 1^st January 1999 (UT)

Col. #2: time in seconds since the first day of the cruise (7^th September 1999) (UT)

Col. #3: latitude (in degree and hundredth of degree)

Col. #4: longitude (in degree and hundredth of degree)

Col. #5: atmospheric pressure (in mbar)

Col. #6: wind speed ( in m s^-1, measured from the boat anemometer at 29.2 meters height)

Col. #7: measured temperature (in °C)

Col. #8: measured pCO2 (in µatm)

Col. #9: salinity (from the thermosalinograph)

Col. #10: temperature in situ (in °C, from the thermosalinograph)

Col. #11:fluorescence expressed in equivalent of chla (in µg/l) (from the Wetstar fluorimeter)

Col. #12: in situ pCO2 (in µatm)

Col. #13: pCO2 at 13°C (in µatm)

Col. #14: density excess (in kg m^-3)
