Submarine canyons are deep and elongated valleys that cut through the seafloor. These geological formations are often referred to by different names depending on their location, shape, and origin. For example, in the Gulf of Mexico, they are commonly known as "canyon systems," while in the United Kingdom, they are referred to as "marine trenches." Some other synonyms for submarine canyons include "underwater gorge," "abyssal valley," "deep-sea channel," and "oceanic trough." Regardless of the term used, submarine canyons play a critical role in shaping the ocean floor and influencing oceanic processes such as sediment transport, nutrient cycling, and deep-sea ecology.
