Marine geophysics specialists aim to refine search area for locating the source of underwater sounds
Marine geophysics experts state that the chances of finding something at great depths on the seafloor, using a remotely operated vehicle (ROV), depend on precisely defining the search area. Dr. Rob Larter, a marine geophysicist, explained during a press briefing earlier this morning, “We’ve all seen the reports of the sounds that have been detected. However, the fact that the search area is still so large would seem to indicate that nobody has confidently been able to locate where those sounds are coming from.”
Each of the floating sonobuoys should be capable of providing a bearing. Thus, depending on the number and location of buoys relative to the sound source, this could provide what submarine search and rescue expert Frank Owen described as “a cross-fix” on the sound.
“That should be possible,” he told me. “But if it’s the Titan, they’re banging on a carbon fiber hull, not a steel hull. It’s like banging on a log instead of banging on a bell – it’s less loud and more muffled, so the sound doesn’t propagate through the water as well.”
Search teams are exploring the possibility of using advanced technologies such as sonar and magnetometers to refine the search area. Precisely locating the source of the sound is crucial for maximizing the chances of success.
However, the unpredictable and challenging nature of the marine environment presents significant obstacles. The complex topography of the seafloor, with its underwater mountain ranges and valleys, can make it difficult to precisely define the search area. Additionally, sound propagation in water is influenced by various factors such as temperature, salinity, and ocean currents, further complicating the task.
Experts are carefully analyzing the collected acoustic data, comparing it with historical records of sound signatures from different types of vessels and underwater structures. This analysis will help discard false positives and refine the search, focusing on the most promising areas.
The challenges faced in underwater searches underscore the importance of advanced technologies and highly trained specialists. Collaboration among scientists, engineers, and search and rescue teams is essential to maximize the chances of success and ensure operational safety.
Search teams are committed to employing all available resources to solve the mystery of the underwater noises. The search continues with the hope that a “cross-fix” will soon be identified, leading to crucial information about the origin of these mysterious sounds.
