Marine Chemistry

Marine chemistry is one of the basic branches of Marine Science. It is a second-level interdisciplinary between oceanography and chemistry. Marine chemistry studieson the chemical composition, the distribution and the chemical properties ofsubstances and chemical processes in each part of the ocean, as well as thechemistry questions about the development and utilization of marine resources.It plays a bond role among each branch of Marine Science.Marine chemistry ofOUC is one of the State Key Disciplines and the important disciplines ofProject 211 and Project 985 disciplinary construction. The disciplineincludes two major parts, i.e., marine chemistry basic research and appliedresearch. At present,the marine chemistry basic research composes four research directions of MarineInterfacial Chemistry, Marine Biogeochemistry,Ecological Chemistry of Marine Pollution, and Marine Organic Geochemistry.

1 Marine interfacialchemistry

Biogenic sulfur (DMS and DMSP)

Trace reactive gases (e.g. CH4, N2O,non-methane hydrocarbons and volatile organic carbons)

Interfacial chemistry (liquid-solid interaction, sea-air exchange)

2 Marinebiogeochemistry

Nutrient cycling and budget

Ecosystem dynamics

Trace metals in water and in sediment

Molecular ecology

Phytoplankton chemotaxonomy

3 Marine pollution andecological chemistry

Eutrophication, mechanism of HABs (red tide) in the costal seas

Behavior of pollutants in the environment: their distribution,change and migration

Environmental capacity of pollutants and environmental management

4 Marine organicgeochemistry

Biomarkers as indicators to environmental changes

Photochemistry in seawater

Organic pollutants and their degradation
