AQ 222 Oceanography I (3 units)
\r\n\r\nObjectives:
\r\n To introduce students to the chemical environment and hydrodynamics of the ocean. Students should be able to know factors that govern major physical and chemical processes in the ocean.

\r\n To introduce students to techniques for analysis of common chemical parameters in sea water and sediment gases and as well as computation of dynamic variables in the ocean.

\r\n\r\nSynopsis
\r\n(i) Introduction to Chemical Oceanography:
Physico-chemical properties of sea water. Carbon dioxide and the bicarbonate system. Nutrient elements: nitrogen phosphorus, silicon, oxygen, organic carbon, and sulphur. Geochemistry of minor/trace elements found in seawater: sampling and analysis. Oxidation-reduction processes and the chemistry of estuaries, lagoons and anoxic environments. Studies on marine sediments; metal speciation in sediments. Analysis of selected seawater and sediment constituents. Selected methods of chemical analysis of sea water.

\r\n(ii) Introduction to Physical Oceanography:
General features of the oceans: major ocean areas and smaller bodies of water, sea floor dimension. Physical properties of sea water: temperature, salinity and conductivity, density, sound light propagation in sea water, measurement of physical properties (instrumentation). Waves, tides and general ocean circulation. Coastal features: beaches, estuaries deltas. Special topics: El Nino, Cyclones & Tsunami. A set of experiments based on the following topics: Water temperature; solar radiation and heat balance; density of sea water and T-S diagrams; water movements.

\r\n\r\nDelivery: 30 lecture hours and 45 hours of practical classes.

\r\n\r\nAssessment: Practical reports 30%, Tests 10%, Mid-semester examination 10%; Final examination 50%.\r\n
