Learning outcomes
Understanding the behaviour of chemical species in the marine environment
Course contents
Composition of seawater, geochemical cycles (residence time), biological interactions, conservative components. Major components, origin, average composition, salinity and chlorinity, methods of determination. Ionic interactions, ion-pairing model. Dissolved gases, saturation anomaly, air-sea exchange. Oxygen and redox potential, anoxic waters, AOU, Redfield ratios. Acid-base equilibria, the carbonate system, pH, alkalinity. Phosphorous, nitrogen and silicon in seawater. Trace elements, speciation. Particulate matter, sources and composition, adsorption. Organic compounds, origin, distribution and fate. Molecular markers for studying marine processes. Distribution of the principal chemical species in the Oceans.
