SONAR
Marine scientists, oceanographers, cartographers, and archaeologists have been working with sonar technologies for years, but recent breakthroughs have made these systems even more valuable to researchers.
What is Sonar?
Sonar (originally an acronym for "SOund Navigation And Ranging") is a system of technologies that uses echo-sounders to create underwater images. Standard side-scan sonars generate images by stitching together swaths of data points collected while being towed behind a surface vessel or submarine (colloquially known as "mowing the lawn"), and multi-beam systems can create detailed images while standing still. Depending on the frequency used, sonar can cover large areas or provide extremely fine image resolution, and they can be combined with other imaging technologies such as LIDAR ("LIght Detection And Ranging") and LADAR ("LAser Detection And Ranging").
Benefits:
- Allows for ROV and submarine operations in near zero visibility conditions.
- Effective means of mapping large areas of sea floor and creating bathymetric models.
- High resolution systems aid in marine life detection and identification.
