（一）中文简介
海洋化学基础是面向海洋科学专业的一门基础课。课程将介绍海洋化学的基本概念、一般原 理，以及它在海洋研究中的应用实例。课程将围绕海水的化学组成、主要生源要素（如碳、 氮、磷、硅、硫等）的生物地球化学循环过程等，介绍海洋环境中各种物质的含量、存在形 式、化学组成及其迁移变化规律，以及控制海洋物质循环的各种过程与通量（物质的来源、 迁移、转化和通量）。
（二）英文简介
Introductory marine chemistry is an important basic course for students majoring in marine science. The objective of this course is to provide an overall introduction of the basic concepts, general principles, and important experimental method in marine chemistry, as well as their applications in common marine environments. The course focuses on the chemical composition of seawater, the biogeochemical cycles of major biogenic elements (C, N, P, Si et al.), important biogeochemical processes (source, transfer, transformation and flux), and useful tools in marine chemistry research.
