Remote Sensing Technologies

Remote sensing technologies such as sonar and magnetometers have revolutionized underwater archaeology by allowing researchers to survey large areas of the ocean floor quickly and accurately. Sonar can create detailed images of submerged structures and artifacts, while magnetometers can detect metal objects buried beneath the seabed. These technologies have greatly expanded our ability to locate and study ancient shipwrecks and submerged settlements.

3D Mapping and Photogrammetry

3D mapping and photogrammetry have enabled archaeologists to create highly detailed and accurate models of underwater sites. By combining data from multiple sources such as sonar, underwater cameras, and drones, researchers can create comprehensive 3D maps of submerged landscapes and structures. This has provided new insights into the layout and construction of ancient civilizations that were previously inaccessible.

Underwater Drones and ROVs

Underwater drones and remotely operated vehicles (ROVs) have allowed archaeologists to explore and document underwater sites with unprecedented precision. These devices can capture high-definition video and images, collect samples, and even perform delicate tasks such as artifact recovery. By using underwater drones and ROVs, researchers have been able to uncover and study ancient artifacts and structures in ways that were previously impossible.
