Course is for students on their 1st year to provide an insight on some basics of Oceanography including physical, biological, chemical and geological oceanography. While introducing the basic principles, the course also aims to provide a solid foundation for marine aspects of advanced courses in environmental sciences. The course is will highlight the multi-disciplinary nature of ocean sciences.
In this course students will find out about history of the ocean and oceanography, coastal geomorphology, ocean currents, both wind-driven surface currents and deep ocean currents driven by the effects of temperature and dissolved salts on water buoyancy. The oceans play an important part transporting heat from low to high latitudes to maintain a balance in the global heat budget. The biological part reviews the different life forms found in the oceans, looking particularly at issues relating to biological productivity and biological diversity, adaptation of life forms and differences between various marine ecosystems. The chemical part will look at the properties of water, the chemical make up of salt, the distribution of dissolved gases and nutrients in the ocean which are vital for life, and the biological and physical factors that govern thier occurrence. This set of lectures will also tackle how the ocean functions as a self-regulating system while highlighting the unique role the ocean plays in maintaining Earth's climate to be hospitable. Human impact on the marine environment is also discussed. The geological oceanography deals with the structure and the development of ocean basins, their bedrock geology and the influx of sediments. How ocean circulation and climate changes of the past are recorded in ocean sediments and mineral resources are also discussed.
