模拟研究沙海蜇消亡过程中海水pH变化及对海水酸化的影响
The variations of pH and seawater acidification during simulated Nemopilema nomurai decomposing process
摘要
Abstract
We studied variations of pH and seawater acidification under the influence of pH, salinity, temperature and N/P in Nemopilema nomurai decomposing process in a stimulation test. It was found that the pH of seawater droped and seawater acidification occurred during degradation of N. nomurai. The pH of seawater firstly droped, then increased and finally gradually stabilized with the decompostion of N. nomurai in the seawater, pH, salinity, temperature and N/P groups, where the pH declined by 0.5~1.8 units. In addition, the time that the pH reached the lowest level was the second day (the seawater group), the third day (the temperature group), the fourth day (the salinity and pH groups), and the fifth day (the N/P group), respectively. Under changes of pH and salinity and the decrease of temperature, the seawater developed more serious acidification during decomposition of N. nomurai. Moreover, when the N. nomurai forms large blooms in the sea area of increasing temperature and eutrophication, decaying jellyfish may cause severe impact on the marine ecosystem.关键词
