The oceans cover some 70% of the earth’s surface and have an enormous impact on the climatic, physical and biological character of the planet. The character and history of development of the ocean basins will be discussed in terms of topics such as ocean sediments, circulation patterns, topography, coastal processes and marine pollution. Occasional weekend field trip may be required.

Means of Assessment
|Lab problem sets (4)
Upon successful completion of this course, the student will be able to:
- Describe and draw plan and profile sketches of the major topographic features of the ocean floor.
- Describe the formation of the major topographic features of the ocean floor in terms of plate tectonic processes.
- Show an understanding of the physical and chemical properties of sea water.
- Show an understanding of the origin and character of surface and deep ocean currents.
- Describe the formation of tides and waves and their effect of ocean basins and coastal margins.
- Describe the processes of erosion and deposition at coastlines and the resulting coastal landforms.
- Describe and identify sediment found in coastal margins and their ancient lithified analogs. Show an understanding of the processes involved in the formation of such sediment.
- Describe and show an understanding of the physical and biological processes which control the development of deltaic and estuarine environments.
- Describe the character of the Fraser Delta and its development over geologic time.
- Show an understanding of the sedimentation process and resulting sediment character and distribution on the ocean floor.
- Describe the change in land/sea relationship over time, how this is determined, and its effect on the distribution of life in the oceans.
- Describe the formation of a variety of oil/gas and ore deposits in the ocean.
- Describe the importance of the oceans as generators of weather and climate patterns and the interaction of the oceans and the atmosphere.
- Describe the likely sources of contamination of the oceans and discuss the various remedial methods used to mitigate the impact of these contaminants.
Course Guidelines for previous years are viewable by selecting the version desired. If you took this course and do not see a listing for the starting semester/year of the course, consider the previous version as the applicable version.
Below shows how this course and its credits transfer within the BC transfer system.
A course is considered university-transferable (UT) if it transfers to at least one of the five research universities in British Columbia: University of British Columbia; University of British Columbia-Okanagan; Simon Fraser University; University of Victoria; and the University of Northern British Columbia.
