The impact of seasonal coastal upwelling on the dynamics of dissolved inorganic carbon (DIC) and sea-air fluxes of CO along the coastal waters of Kochi was investigated during 2015, as a part of Ecosystem Modelling Project. The surface water pCO varied from 396 to 630μatm during the study period. Significant inter-seasonal variations were found in the distribution of physico-chemical variables and surface pCO. An increase of 102.1μatm of pCO was noticed over a two-decade period with a rate of 5.3μatmy. There was an agreement between the fluxes of CO and net ecosystem production (NEP) with respect to the trophic status while NEP was higher than CO fluxes by a factor of 3.9. The annual net ecosystem exchange (NEE) was estimated to be 15.02mmolCmd indicating that the coastal waters of Kochi are highly heterotrophic in nature.
作为生态系统建模项目的一部分，于2015年对科钦沿海水域季节性沿岸上升流对溶解无机碳（DIC）动态及CO海气通量的影响进行了研究。研究期间，表层水pCO在396至630μatm之间变化。在物理化学变量和表层pCO的分布中发现了显著的季节间变化。在二十年期间，pCO增加了102.1μatm，速率为5.3μatmy。就营养状态而言，CO通量与净生态系统生产（NEP）之间存在一致性，而NEP比CO通量高3.9倍。估计年净生态系统交换（NEE）为15.02mmolC m⁻² d⁻¹，这表明科钦沿海水域本质上是高度异养的。
