1. Build background.
Explain to students that marine, or ocean, maps can be used to provide information about a variety of activities, distributions, and earth and ocean features. For example, ocean maps can show areas of fishing activity, climate variation, fish distribution, and currents. Ask: What information does comparing maps with all of these features give you? (information about the relationship between these variables and the overall geographic area that has been mapped) Tell students that this type of comparison is one of the fundamental advantages of Geographic Information Systems, or GIS.
2. Examine different ocean maps.
Display for students the MapMaker Interactive. Switch between the different base maps, accessed from the base map tab at the top right. As you display each layer, ask: What information does this map provide about the ocean? Describe it. Then add map layers to explore other information related to the ocean and ask the same questions. Find these map layers in the tab at the top right and add them to your map:
- Volcanic Eruptions
- Sea Surface Temperatures
- Ocean Surface Currents
- Ocean Chlorophyll
- Plate Tectonics
- Surface Elevation
3. Evaluate the purposes of the different maps.
Have a whole-class discussion. Ask:
- What is the purpose of these maps?
- How do you think maps like these can help you learn about the ocean?
- Why is it useful to create maps?
- Why is it good to have maps that show information other than just the “basics,” such as the locations of the continents or major islands?

Maps can be extremely valuable in helping ocean scientists answer their research questions. Marine maps can provide information about a variety of activities, distributions, and earth and ocean features.
