Underwater landmarks

Underwater landmarks are natural or man-made features on the ocean floor that help navigation and mapping. Examples include distinctive rock formations, shipwrecks, coral reefs, or underwater mountain ranges. These landmarks are used by divers, submarines, and researchers to orient themselves, track locations, and explore the underwater environment. Just as mountains or buildings serve as reference points on land, underwater landmarks provide critical navigation cues in the often featureless ocean depths, ensuring safe and accurate movement beneath the surface.
