為了明瞭有機碳在南海北部大陸棚及大陸坡的沉積狀況,利用箱形岩心採樣器共收集了27站的沉積物,取其0~2公分的表層沉積物來分析其總有機碳(TOC),總氮(TN),總硫(TS)的含量。分析結果顯示:在大陸棚地區TOC分佈除了珠江口附近之外,含量皆很小,而大陸坡的中段(深於700m)則有富集的現象,含量在0.6~0.8%間,顯示此處為碳的堆積中心。總氮的含量則與總有機碳的含量呈良好的線性關係,且其斜率與Redfield Ratio非常接近,顯示富集的有機碳來自海源。總硫含量亦與總有機碳含量相關,其斜率為0.11。
In the northern South China Sea, sediment samples were collected at 27 stations on the continental shelf and slope in order to understand the deposition of organic carbon. Total organic carbon (TOC), total nitrogen (TN), total sulfur (TS) and total calcium carbonate contents were determined for the surficial sediments. On the shelf, the TOC abundance is depleted except near the Pearl River mouth. On the slope, relatively high abundance of TOC (0.6-0.8%) is found in the middle slope, indicating a potentially important carbon sink. The TN content is well correlated with TOC content with a ΔN/ΔC ratio near the Redfield ratio, indicating that the additional organic matter in the more enriched region is from marine origin. The TS content also correlates linearly with TOC content with a ΔS/ΔC ratio of 0.11.
