春季东海北部近岸水体中的溶解无机碳和有机碳的分布特征及其影响因素
Dissolved inorganic and organic carbon in the North of East China Sea （ECS） coastal waters in spring
摘要
Abstract
Concentrations and distributions of dissolved inorganic carbon （DIC） and organic carbon （DOC） as well as their relationships with temperature, salinity, and dissolved oxygen in the North of ECS Coastal Waters during April in 2010 were analyzed. The average concentrations of DIC in surface and bottom water of our study area were 24.54mg/L and 25.03mg/L, respectively. The average concentrations of DOC in surface and bottom water of our study area were 0.96mg/L and 0.87mg/L, respectively. The characteristics of distributions of DIC and DOC were both higher near the coastal line and lower in outer sea. There were high concentrations at northeast of the survey area because of inputs by Changjiang River. As to vertical distribution, the concen- tration of DIC in surface water was lower than that in bottom water, while the vertical distribution of DOC was contrary to that of DIC. Relationships between DIC and DOC, and their relationships with temperature, salinity, and AOU indicated that temperature was the main factor influencing DIC distribution, while terrestrial input and biological activities played important parts in distribution of DOC.关键词
