Description including Unit Aims
An overview of the physical, chemical and biological aspects of oceanography in the sense that they relate to environmental geosciences.
Aims:
- qualitatively describe the processes that shape the ocean basins.
- provide a qualitative analysis of the dynamics of wind-driven surface current systems, and of density-driven circulation in the deep oceans.
- investigate the biogeochemical cycling of elements in the seawater solution, and water-sediment interactions on the seafloor.
- describe and explain interactions between marine plants and animals in relation to the physical and chemical properties and dynamic behaviour of the sea water in which they live.
- introduce the aspects of the ocean-atmosphere system that are relevant to climate change on the Earth on timescales of 102-106 years.
- assess the role of oceans in controlling levels of atmospheric CO2.
Intended Learning Outcomes
On successful completion of the unit you will be able to:
- describe the processes that shape the ocean basins.
- describe and explain the reasons for the temperature, salinity and density structure of the oceans.
- explain how deep water masses form and describe the global conveyor system.
- discuss the distribution of elements in seawater and identify their sources and sinks.
- debate the abiotic factors affecting biological productivity in the oceans
- discuss the carbon and oxygen cycles in the ocean-atmosphere system.
- analyse the processes that lead to the observed regional distribution of biogenic carbonate and siliceous sediments on the ocean floor, describe early diagenetic processes in deep sea and hemi-pelagic sediments.
- analyse palaeoclimate data and draw inferences from such data regarding the past climate of the Earth.
- discuss why oceans are important in the atmospheric CO2 cycle and critically analyse the different hypotheses as to how the oceans respond to, or cause, variations in atmospheric CO2 on a variety of timescales
