Abstract

In order to quantify the temporal variations of ocean properties, the MINERVE programme was designed to perform time-series measurements in the Southern Indian Ocean south of Australia. In the sub-Antarctic region (SAR, 48.5 ± 6.0°S), the mean CO2 flux increased from spring to summer from -6.8 mmol.m-2.d-1 in October 2005 to -9.9 mmol.m-2.d-1 in February 2006. In the Permanent Open Ocean Zone (POOZ, 57.5 ± 3.0°S), we observed lower pCO2 in summer than in spring (340 and 398 μatm, respectively). The mean CO2 flux showed large temporal variations from -0.2 mmol.m-2.d-1 in October 2005 to -8.2 mmol.m-2.d-1 in February 2006. The large temporal variation was associated with increased phytoplankton biomass. In the Continental Antarctic Zone (66.0 ± 1.0°S), the mean CO2 flux decreased from +14.9 mmol.m-2.d-1 in October 2005 to -8.4 mmol.m-2.d-1 in February 2006. In winter and spring, deep water mixing and seasonal sea-ice strongly increase pCO2sea above atmospheric level. In contrast, during summer, the effect of biological CO2 uptake decreased pCO2sea. Furthermore, these data allowed us to parameterize AT and CT as a function of temperature and salinity.
