Deep-sea exploration refers to the study and investigation of the ocean’s depths, typically below 200 meters (656 feet) where sunlight does not penetrate. This field encompasses the use of advanced technologies, such as submersibles, remotely operated vehicles (ROVs), and deep-sea sonar, to explore underwater landscapes, marine ecosystems, and geological formations. Deep-sea exploration aims to understand unique biological communities, discover new species, assess natural resources, and study environmental changes in the ocean. It plays a critical role in marine biology, oceanography, and climate science, enhancing our understanding of the Earth’s largest and least explored habitat.
