Submarine canyons, also known as submarine valleys, are underwater landforms that are often steep and deep, resembling canyons on land. These formations are located on continental margins and can be several kilometers long and several hundred meters deep. Other synonyms for submarine canyon may include submerged gorge, submarine ravine, undersea channel, abyssal ravine, and marine trench. These deep and narrow canyons provide habitats for a wide range of marine species and have significant ecological, economic, and scientific importance. Studying submarine canyons can help scientists better understand ocean currents, sediment transport, and the geology of the seafloor.
