Abstract:
The partial pressure of CO2 in the surface waters
(pCO2sw) of the Southland Front east of New Zealand was determined over one annual cycle
in 1992/93. Associated parameters of temperature, salinity and nutrients were also measured. Both the modified subtropical waters of the Southland
Current and the cooler subantarctic surface waters were undersaturated with CO2 with respect to the atmosphere. The maximum
ΔpCO2 of –150 µatm was measured in April 1993. A simple model taking into account the
effects of temperature, biological activity and air–sea exchange applied to subantarctic surface water indicated that at different times of the year
changes in sea surface temperature, biological activity and mixing processes are the dominant controls of
pCO2sw .
