Seafloor mapping is the process of creating detailed maps of the ocean floor. This is done using various technologies, such as sonar and satellite imagery, to measure the depth and shape of the seabed. These maps help scientists understand underwater features like mountains, valleys, and shipwrecks, as well as the habitats of marine life. The information gathered from seafloor mapping is crucial for many applications, including marine biology, fishing, and environmental protection. It also aids in navigation and helps in planning for activities like oil drilling and underwater construction.
