| 摘 要： | 分析表观耗氧量、滴定碱度及总二氧化碳量等资料来研判红海及亚丁湾间之海水交换。结果显示,红海深层水的方解石及霰石饱和度均比亚丁湾和阿拉伯海深层水的饱和度高。红海全水柱之方解石和霰石都处於过饱和状态,亚丁湾和阿拉伯海中各深度之方解石亦呈过饱和状态,但霰石的饱和探度则大约在500m左右。分析深层水之生物体无机碳与有机碳的分解比值,可以发现此地区深层水中,大约有25％的总二氧化碳增加量是由无机碳酸钙溶解而来。

| Abstract: | The apparent oxygen utilization, titration alkalinity and total CO2 data have been used to study the exchange of seawater between the Red Sea and the Gulf of Aden. The Red Sea is supersaturated in both calcite and aragonite and the degrees of saturation are higher than found in the Gulf of Aden. The Gulf of Aden and the Arabian Sea are supersaturated in calcite but the arazonite becomes undersaturated below 500m.Analysis of the biogenic inorganic carbon/organic carbon ration indicates that about 25% of the increase in total CO2 originates from the dissolution of calcium carbonate. |
