Marine Trackline Geophysical Database for Side-Scan Sonar Data
Marine Trackline Geophysical data represented within the side-scan sonar data are from towed instruments closer to the seafloor that use sound to image features on the ocean floor. This technique can create shadows like shining a flashlight, which help determine size and features. This system is often used to map cultural heritage sites like shipwrecks, to characterize the makeup of the seafloor, and can even be used to help biologists identify habitats of marine animals.
