Abstract:

The partial pressure of carbon dioxide in surface water and atmosphere in the Prydz Bay and its adjacent waters was determined by using infrared analysis from December 1991 to January 1992. The results showed that the distribution of P CO 2 in surface water appeared to be lower in the coastal sea than the open sea,and its distribution was principally controlled by biological activity. The CO 2 flux was estimated by using the flux model, the mean CO 2 air-sea flux in the research area was about -71.9 g/(m 2·a),its potential flux uncertainties might result from the wind dependent exchange coefficient.
