What are advantages and disadvantages of submersibles?

Answer 1

Submersibles offer the advantage of deep-sea exploration and research, allowing scientists to study underwater ecosystems and geological formations that are otherwise inaccessible. They can operate at significant depths, providing valuable data for oceanographic studies. However, their disadvantages include high operational costs, the risk of mechanical failure under extreme pressure, and limited mobility compared to autonomous underwater vehicles. Additionally, they require specialized training for pilots and crew, which can further increase operational complexity.
