An introductory subject on the principles of marine chemistry and marine chemical ecology. Definition and history of marine chemistry and chemical ecology. Properties and chemical composition of seawater. Major elements in seawater. Conservative and non-conservative elements. Biogeochemical cycles. Horizontal and vertical distribution of biolimiting elements. Determination of nutrients in seawater. Minor or trace elements in seawater, sediments and marine organisms.
