The CO2 increase in the ocean due to the uptake of anthropogenic CO2 is of major concern, due to potential changes in future ocean CO2 uptake that might be driven in a direction of relative less CO2 uptake in the future then today and the companying lowering of ocean pH. In this study we investigated the variability of CO2 system parameters, focusing particularly on the pH and how it changes with changes in other parameters like: temperature (T), salinity (S), total dissolved inorganic carbon (CT ), and total alkalinity (AT ). For Arabian Sea the data from the United States Joint Global Ocean Flux Study (US{JGOFS) in 1995 were used. For the Red Sea data from the Geochemical Ocean Section Study (GEOSECS) in 1977 and the Mer Rouge (MEROU) cruises in June and... |
