The Mariana Seamounts are a group of underwater mountains located in the western Pacific Ocean, near the Mariana Trench. These seamounts are formed by volcanic activity and rise from the ocean floor, creating unique ecosystems. They are part of the larger Mariana Arc, which is a volcanic island arc associated with the subduction of the Pacific Plate beneath the Mariana Plate. The seamounts are significant for marine biodiversity, providing habitats for various species, including fish, corals, and other marine life. They also play a role in ocean currents and nutrient distribution, influencing the surrounding marine environment. The study of the Mariana Seamounts helps scientists understand geological processes and the impacts of climate change on ocean ecosystems.
