The Mariana Trench

The Mariana Trench

This resource provides an overview of the Mariana Trench, the deepest of 22 known deep-ocean trenches, located in the Pacific Ocean to the east and south of the Mariana Islands near Guam. Topics include the unique adaptations of creatures to the cold, darkness, and extreme pressure of the abyssal zone, the depth and physical properties of the trench itself, and a brief discussion of the tectonic forces that produced the trench-island arc system of the Mariana Arc. There is also a history of exploration of the trench, a discussion of measurements of ocean depth, and links to books, videos, and online references on related topics.
