简介：酸不稳定的硫化物(AVS)在影响二价的猫的毒性起一个重要作用，是众所周知的在缺氧的沉积以内的离子的金属。在学习在Jiaozhou海湾以内从潮滩收集的沉积岩心试样，中国，我们发现AVSconcentration逐渐地与深度增加并且从高潮滩减少到低潮滩区域。我们基于同时提取的金属(SEM)和AVS的臼齿的比率在潮滩评估了化学活动和重金属的简历可获得性。SEM/AVS的价值通常除了表面层在这个区域是不到1，它建议重金属仅仅在表面层举办化学活动。SEM最高度在氧化还原作用层的边界被集中。SEM在整个潮滩有类似的深度分布。低潮滩沉积的Theaeration显示SEM逐渐地经由孔隙水搬到更深的地点。

简介：河口的分布给溶解有机物(CDOM)涂颜色是physicalbiogeochemical过程的联合结果。遥感动态地高度被需要到监视器河口CDOM。从四季节的巡航在situ数据使用，一个算法被开发在400nm估计CDOM吸收系数(在Zhujiang(珀尔河)的CDOM(400))河口(ZJE)。Rrs(667)/Rrs(443)和Rrs(748)/Rrs(412)。由使用它在水上节制分辨率成像分光辐射函数从2002～2014的卫星(MODIS/Aqua)数据，季节的气候学在ZJE的CDOM(400)被计算。CDOM分布主要地走水路被影响来自Zhujiang河的分泌物并且在水下地形学。沿着对一个水深度坡度垂直的节，季节CDOM(400)指数地减少了(y=aebx,b<0)，但是与在季节之中的大差别。河流的新鲜的水是在ZJE的CDOM的主要来源。有增加咸度的Fulvic酸部分减少。用发达算法，保守CDOM混合方程，和河分泌物，在从2002～2014的夏天和冬季的溶解的器官的碳(文档)的有效河流的结束成员集中和流动首先从MODIS/Aqua数据被估计。两有效河流的结束成员文档集中和流动是断然与河有关排出，显著地在有为集中的0.698的R2的夏天并且0.9657为流动。

简介：水样品从2002年8月在四巡航以后在Changjiang河口的沿海的区域被收集到2003年5月。溶解的无机的砷(DIA)的季节变异分布被分析。结果证明DIA的分布被陆上的输入和自台湾东面的菲律宾海流向日本的暖流表面下的水(KSSW)的侵入主要影响。全部的溶解的无机的砷(TDIA)的Theconcentration从冬季连续地减少了到夏天，当它在秋天增加了时。TDIA的分布与咸度显示出一些关系并且推迟了微粒物质(SPM)。在DIA种形成之间的关系(包括亚砷酸盐[作为(Ⅲ)]并且砷酸盐[作为(Ⅴ)])，生物活动和磷酸盐的可获得性为巡航2002年8月在学习区域被调查。比率作为(Ⅲ)/TDIAs与磷酸盐集中的减少增加了。在底部水里，同样(Ⅲ)/TDIAs比率与增加N/P减少了。TDIA的集中减少了在有害海藻的花蕾(HAB)的出现以后的28.7%approximately因为由水藻的砷酸盐的举起。进一步的学习在有害海藻的花蕾的出现期间在他们的垂直或水平的侧面和举起机制关于砷来源/水池关系被需要。
