syllabus.pngSYLLABUS REQUIREMENTS


1. Introduction to oceans
distribution of oceans
Describe the distribution of oceans and ocean currents.
morphology of oceans
Describe the main features of oceanic crust and ocean floor morphology.

Explain the occurrence of oceanic volcanic features, trenches, transform faults, mid-ocean ridges and rifts in terms of plate margins.
oceanic water
Describe the horizontal and vertical spatial variations in the temperature and salinity of ocean water.

2 hours
2. Oceans and climate
energy transfers
Explain the thermal transfers of energy within oceans and the importance of oceanic conveyor belts.
El Niño Southern Oscillation (ENSO)
Explain the atmosphere–oceanic interactions associated with ENSO.
Explain the El Niño and La Niña phenomena and their climatic, environmental and economic effects.
carbon dioxide
Examine the role of oceans as a store and source of carbon dioxide (CO2).
4 hours
3. The value of oceans
resource base
Identify the biotic and abiotic resources of continental shelves, oceans and ocean floor deposits.
fishing
Examine the spatial and temporal consequences of overfishing.
case study
Evaluate a case study of a conservation policy implemented to provide sustainable fish yields.
waste
Describe the sources and distribution of pollution in the oceans.
4 hours

Discuss the implications of the pollution of oceans by the disposal of radioactive material, oil, and chemical waste.
3 hours
4. Geopolitics of oceans

Discuss the sovereignty rights of nations in relation to territorial limits and exclusive economic zones (EEZ).

Examine a geopolitical conflict in relation to an oceanic resource, other than fishing.
3 hours
5. Coastal margins
physical characteristics
Examine the relationship between coastal processes (tides, wave action, littoral drift, wind action) lithology, subaerial processes and different coastal landforms.

Identify the major landforms of beaches, dunes and cliffs along advancing and retreating coasts.
4 hours
management strategies
Discuss the conflicts that arise from competing land uses and from attempts to manage coastal hazards (tsunamis and storm surges, erosion, cliff failure), pollution, habitat restoration and aquaculture.
case study
Describe the conflicting pressures on a particular coastline.
Discuss the management strategies adopted to resolve these pressures and evaluate their effectiveness.
6 hours
6. Coral reefs and mangroves

Examine the development and the environmental and economic value of coral reefs and mangrove swamps.

Analyse the causes and consequences of the loss of coral reefs and mangrove swamps.
4 hours

skills.pngGLOSSARY

Oceanic conveyor belts
A global thermohaline circulation, driven by the formation and sinking of deep water and responsible for the large flow of upper ocean water.
Exclusive economic zone (EEZ)
An area in which a coastal nation has sovereign rights over all the economic resources of the sea, seabed and subsoil, extending up to 200 nautical miles from the coast.
Advancing coasts
Depositional coasts that are accreting as a consequence of deposition of sediment and/or the infill of coastal marshes. Advancing coasts may also arise from a negative change in sea level (sea level fall or uplift of land).
Retreating coasts
Coasts along which the dominant processes are erosional, resulting in the coastline moving inland. Retreating coasts may also arise from a positive change in sea level (sea level rise or fall in land level).
Littoral drift
The movement of sediments along a coast by wave action, also called longshore drift.
