Description

The oceans cover more than 70 per cent of our planet. In this free course, The oceans, you will learn about the depths of the oceans and the properties of the water that fills them, what drives the ocean circulation and how the oceans influence our climate.

Course learning outcomes

After studying this course, you should be able to:

  • Explain in your own words, and use correctly, all the bold terms in the text
  • Identify, classify and interpret various features visible on the ocean floor
  • Interpret temperature and salinity plots recorded in the oceans
  • Interpret spatial maps of temperature and salinity and deduce ocean circulation
  • Evaluate the role of the different oceans in the global ocean circulation.
