2.1 Investigating the Trench

1. Import the data, and display it as an image in your report. Be sure to label your axes and have latitude increase to the north (in the

positive y-direction) and longitude increase to the east (in the positive x-direction).

2. How deep is the deepest point sampled in the trench? What are its latitude and longitude?

3. The ocean floor can be nominally defined in this region at a depth of 6 kilometers. What is the average depth of the trench, that is,

the mean depth among all points deeper than the ocean floor?
