This expedition should take about 100 minutes to complete – it is a long one. Consider the extra time associated with part 14 as homework.

Objective: Students will learn about the features of the seafloor by completing an oceanographic expedition across the Atlantic and Pacific Oceans. The methods used in the expedition are only a few of the scientific methods that are used to study the seafloor and its features, which cover the majority of the Earth's surface.   In addition, students will apply what they have learned to identify the seafloor features off central California.

Why is it important to study the seafloor?

    Governments and industries spend hundreds of millions of $$$ each year to understand the shape of the earth's surface.

    This information is critical in solving the mysteries of the earth's formation.

    Global shipping and communications industries depend on this information for the safe, speedy exchange of goods, people and information. 

    Even the sophisticated guidance systems on submarines, airplanes and intercontinental missiles require an understanding of the shape of the Earth in order to travel an accurate course.
