Description

This unit examines the natural processes occurring in marine, coastal and inland aquatic environments and the significance of these processes for managing these systems. In particular, the unit explores both the effects of these processes on aquatic ecosystems and how they may enhance or reduce the impact of human activities in aquatic systems.

Prerequisite Rule

(Students must pass 1 units from SCI1185 AND Students must pass 1 units from SCC1111, SCC1123)

Equivalent Rule

Unit was previously coded SCM2202

Learning Outcomes

On completion of this unit students should be able to:

1. Analyse the impacts of humans on aquatic environments.
2. Describe the physical and chemical properties of water.
3. Design and undertake field assessments of water quality and hydrological parameters.
4. Develop conceptual models of the biogeochemical cycles for water, phosphorus, nitrogen and carbon, sulphate, iron and silica for specific aquatic ecosystems.
5. Evaluate and describe the major interrelationships between physical, chemical and biotic processes within aquatic environments.
6. Understand the relationships between geomorphology of land-based water bodies, the coastal zone and the open ocean and biological aquatic processes.

Unit Content

1. Chemical controls of aquatic environments: nutrient cycles (N, C, P), cycles of sulphate, iron and silica. Brief introduction to the impacts of human activities on these cycles.
2. Hydrological cycle, providing a brief overview of the type of aquatic environments found from source to sea.
3. Light environment: colour, light penetration. Distribution of heat: stratification (including salinity), mixing.
4. Physical and chemical properties of water: molecular structure, specific heat, density, viscosity, surface tension, diffusion, pH, conductivity, ionic composition, redox, dissolved oxygen.
5. Physical controls of aquatic ecosystems: hyrodynamics (waves, tides, currents, flow), erosional and depositional processes, sediment types.
6. Production: primary and secondary, microbial loop, trophic status.
7. Techniques for water quality and biological monitoring in a range of aquatic environments, including sampling and analytical problems and limitations.

Additional Learning Experience Information

Lectures, laboratory work, field work.
