海洋化学是随着海洋学各分支学科的发展而发展起来的。目前,海洋化学的研究范围已经非常广泛,研究对象不仅包括海水,而且还包括海洋沉积物和海洋生物体,分析测定的项目多达几十种。不论是在综合性还是专业性海洋调查中,都会获得大量海洋化学资料。在大多数情况下,现场取得的调查资料须经过适当的加工处理之后才能用于分析和研究。从不同的目的出发,这些处理工作的复杂程度可能有很大的差别,就一般而论通常包括以下步骤: Ocean chemistry is developed with the development of various branches of oceanography. At present, the research scope of marine chemistry has been very wide. The research objects include not only seawater, but also marine sediments and marine organisms. There are dozens of projects for analysis and determination. Whether in a comprehensive or professional marine survey, will get a lot of ocean chemistry information. In most cases, the survey data obtained on site must be properly processed for analysis and research. Proceeding from different purposes, the complexity of these processes may vary widely and, as a general rule, the following steps are generally involved:
