自然资源部第三海洋研究所-防城港临近海域环境调查-大面观测-海水化学要素数据集-20140324-20140325

本数据集针对南海海域，收集了1980-2015年多个南海海域综合调查项目工作，包括水温、盐度、溶解氧、氧饱和度、pH值、总碱度、硝酸盐、亚硝酸盐、铵盐、活性磷酸盐、活性硅酸盐等海水化学要素调查数据。数据集包含50个项目，109100个数据，主要通过对收集、调查的历史资料规范化整理、分析综合而成。

This dataset targets the South China Sea, and collects data from multiple comprehensive marine survey projects carried out in this sea area during 1980–2015. The survey data cover marine hydrochemical elements including sea water temperature, salinity, dissolved oxygen, oxygen saturation, pH value, total alkalinity, nitrate, nitrite, ammonium salt, reactive phosphate and reactive silicate. The dataset consists of 109,100 valid records from 50 projects, and is mainly developed through standardized sorting, analysis and synthesis of the collected historical survey materials.
