Hello there, I require assistance. Next week, I'll be giving a presentation on underwater surveys. I don't know much about this subject, but I'm doing some research. If anyone could provide some information on this, it would be greatly appreciated. What technologies are used for underwater inspections? While searching online, I came across this information about underwater surveys, which proved to be quite informative and useful. Please let me know if you have any additional information. Thank you very much.
