This laboratory covered all major aspects relevant to physical oceanography. Much more can of course be said about regional details in the topography of the world ocean. This would expand on aspects covered earlier but would not add new basic insight into processes of physical oceanography. We therefore end the discussion of ocean topography at this point.

To complete this exercise, here is a quick test to see how well you followed the material:

Where is the Mid-Atlantic Ridge?.

Identify the ridge on the map and click on it.
