Mapping the Atlantic Ocean Floor- From Cape May to Cape Roca!
In this activity, you will learn how scientists use math to find out about the ocean floor. The data in the table below represents various measurements of the depth of the Atlantic Ocean between Cape May, New Jersey and Cape Roca, Portugal. You will use this data to construct a profile, or side view, of the floor of the Atlantic Ocean between these points.

1. What is the minimum depth and how far from Cape May is it located?

1. What is the maximum depth and how far from Cape May is it located?

1. Convert the maximum Atlantic Ocean depth into miles (1 mile = 5,280 ft)

1. Notice that the data for ocean depth is missing for 1125, 2725, and 3400 miles. Estimate and write in the value for ocean depth.

1. Plot the distance and depth on the graph. Once each point it plotted, CAREFULLY connect the data points.

1. AFTER creating the ocean floor profile, LABEL the Mid-Atlantic Ridge. At what distance do you find its highest point?

1. In order to convert sonar data into depth measurements, scientists use the following equation: Depth = ½ V x t where V is a constant = 5,806 feet per second and is the speed of sound in water. Using the formula, complete the table to calculate depth.
