Part 1 –

Download and install GeoMapApp and open a dataset. Explore GeoMapApp's features and make a sketch of a visualization that shows an area of the seafloor.

Part 2 –

Explore the Atlantic and Pacific ocean basins. Collect data on ocean depths across one of the basins along one or more latitudes.

Part 3 –

Combine profiles from separate latitudes to build a whole-class contour map of an area of the seafloor.

Part 4 –

Compare the contour map produced by hand with visualizations of the same area produced by GeoMapApp. Use GeoMapApp's Grid function to produce contour maps and profiles for other areas of the seafloor.
