continental shelf mapping

Continental shelf mapping involves creating detailed charts of the underwater land extending from coastline regions into the ocean, where the seabed gradually slopes downward. Using tools like sonar, satellites, and underwater vehicles, scientists measure water depths and seabed features to produce accurate topographic maps. This mapping helps identify resource-rich areas, supports navigation safety, and enhances understanding of marine ecosystems. Essentially, it provides a precise underwater "cartography" of the continental shelf, which is the relatively shallow, submerged extension of a continent that plays a crucial role in global oceanography, ecology, and resource management.
