Goals
`````
* Understand the water masses, circulation and other aspects of descriptive physical oceanography of the Global Ocean & its marginal seas

To accomplish this, one will:
`````````````````````````````
* Learn to extract data subsets from map plots
* Learn how to use advanced JOA tools for working with basin-scale data sets

Tools
`````
* JOA Section Editor
* Interpolations Options dialog box
