Table 9.3 lists the approximate surface water salinity at various latitudes in the Atlantic and Pacic Oceans. 5. Using the data, construct a salinity curve for each ocean on the graph, Figure 9.10. Use a different colored pencil (or symbol) for each ocean. Then answer questions 6 - 9.

What are two factors that control the concentration of salts in seawater? 8. What is the cause of the difference in surface water salinity between equatorial and subtropical regions in the Atlantic Ocean? 9. Of the two oceans, the Atlantic and the Pacic, which one has higher average surface salinity
