Purpose:

To describe and interpret the depth distribution of the ocean salinity.

Average Annual Sea Surface Salinity

The data to describe:

The image with data above is from Global Ocean Data Viewer. It is the annual climatology of the salinity, which represents the ocean salinity averaged over many years.

The task:

Your job is to write a short scientific discussion of the depth dependence of the salinity data shown in the figure above and to develop a model explaining this data. 

Describe: First, describe the salient features of the depth data. Be brief, but don't miss important features.  Look at the most obvious salinity variations. Feel free to mark on the figure. When you write down your observations, use data values and locations to illustrate your statements. Be as quantitative as possible. Since latitude and longitude are not marked on the plot, you can estimate, or annotate the plot to indicate geographical locations.

Interpret: You should begin your description by mentioning the main phenomena that affect the salinity of the ocean at depth.
