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. Bioaccumulation and biomagnification
of trace elements in marine organisms. Trace element speciation and toxicity. Carbonate
equilibria in the sea. Ecological role of dissolved organic carbon (DOC) compounds
in seawater. Chemical communication conveyed by DOC, allochemical effects. Invertebrate-toxic
host relationships, symbiosis and mutualism, coral spawning chemistry. Fatty acids,
steroids, terpenes, nitrogenous compounds, fish and shellfish toxins. Potential applications
of marine biotechnology-ectocrines and filter feeders, mollusk chemistry, tunichromes,
metal ion sequestering and pharmacological activity.
