INTEGRATED STUDY OF OCEAN WARMING, CO₂ UPTAKE, AND ACIDIFICATION UNDER ANTHROPOGENIC EMISSIONS

Abstract

The study examines the influence of greenhouse gas pollutants on ocean waters. A key parameter describing ocean properties is pH, whose decrease negatively affects marine flora and fauna. Ocean surface temperatures rise over time due to the absorption of anthropogenic heat, with the most significant processes occurring within the upper 10 m layer. Phytoplankton, increasingly important for addressing ecological issues, is also affected by decreasing pH levels. To quantitatively describe ocean conditions, a thermodynamic calorimetric method is proposed. Validation is performed through a comparison of calculated and observed temperature variations, as well as the estimated specific heat capacity of ocean water. Measured pH variations are also compared with calculated values. The resulting expression incorporates temperature change, absorbed heat, and CO₂ content. Phytoplankton photosynthetic activity is further assessed in relation to potential cultivation areas on the ocean surface.
