Figure 1. Global average surface salinity.

The object of this activity is to attempt to explain the global pattern of sea surface.
The map (figure 1) shows the global annual average surface salinity.

a) First, observe and describe the main surface salinity pattern. Does it mostly vary with latitude, or are there other variations of note?

 

b) Identify processes that affect the salinity at the sea surface. For example, xxx affects salinity and and the plot yyy shows global observations of this parameter.

 

c) What additional data could be used to test your idea?

 

If this exercise is done in class, the instructor will display the data you request. If you are not in class, use the Global Ocean Data Viewer to access the relevant data.

d) Write an argument that supports your theory on the causes of the surface salinity distribution shown in figure 1.
