The Laurentian Abyss is believed to be around 6,000 meters deep. It's located off the coast of Canada on the Atlantic side. The bottom of the trench hosts a very unique ecosystem. Underwater thermal vents bring nutrition to the many organisms that live there. These beings can survive there without sunlight. For more information about the Laurentian abyss, visit:
