我们报告了在Sungai Sementa Besar河口采集的地下水样本中的各种氮。Sungai Sementa Besar是马六甲海峡外一条长约4.5公里的小溪，排干了马来西亚半岛西海岸的红树林。这条以潮汐为主的水道，泉水时水位高低差大于4.5米，小潮时水位差仅为1.0米，河口盐度在30‰以上。大雨过后或潮汐淹没森林地面时，河口处的无机氮值会增加10倍之多。在这些条件下，颗粒物和总有机氮在口腔也有所增加。其他时间的有机投入也相对较高。
We report on various species of nitrogen in subsurface water samples taken at the mouth of Sungai Sementa Besar, a creek about 4.5 km long off the Straits of Malacca and draining a mangrove forest on the west coast of Peninsular Malaysia. This tide-dominated watercourse shows a range greater than 4.5 metres from low to high water during springs, only 1.0 m during neaps, and salinities at the mouth of 30‰ or greater. After heavy rains or when the tides inundate the forest floor, inorganic nitrogen values increase as much as tenfold at the mouth. Particulate and total organic nitrogen also increase at the mouth under these conditions. There were also comparative highs of organic inputs at other times.
