The "Passage of the Deep" refers to a significant underwater route that connects various oceanic regions. This passage is crucial for marine navigation and plays a vital role in global shipping and trade. It is characterized by deep waters and complex currents, making it an important area for both commercial and scientific exploration. Additionally, the passage is home to diverse marine ecosystems, supporting a variety of species, including fish, marine mammals, and coral reefs. Researchers study this area to understand its ecological importance and the impact of climate change on oceanic environments.
