Studying the variation of the CO2 system in seawater of Bania's coast- Syria

We studied the effect of CO2 system parameters in the coastal seawater of Banias City during the year 2022, their effects on salinity and temperature, and the resulting changes in pH values of marine water from several sites distributed along the coast.The results show decreasing temperature and salinity of the water in winter (17.11-17.72°C,36.51-36.98‰)respectively, increasing the absorption of CO2 of water leading to increasing the concentrations of total inorganic carbon (2250.3-2280.3μmol/kg),alkalinity (2389.3-2395.9μmol/kg)and decreasing pH values of seawater (7.721-7.782).There was a change in temperature and salinity of the seawater in spring (21.94-22.42°C,37.51-37.88‰respectively), and in autumn (19.88-19.92°C,37.35-37.45‰respectively), in addition to the decrease in the concentrations of total inorganic carbon (2088.4-2154.2μmol/kg,2219.9-2237.9μmol/kg),alkalinity (2445.2-2449.6μmol/kg,2456.3-2470.8μmol/kg)and pH values of seawater (7.632-7.684)(7.562-7.673).The study revealed increasing temperature and salinity of the seawater in summer (26.61-27.36°C,38.41-38.67‰respectively), and decreasing the biological activity.This was accompanied by increasing the concentrations of both total inorganic carbon (2306.6 -2381.5μmol/kg),alkalinity (2526.1-2550.7μmol/kg),and pH values of seawater (8.068-8.070).
