what do you call people who use the submarine under water to descover

Answer 1

People who use submarines to explore underwater environments are typically referred to as marine explorers or underwater explorers. If they are specifically conducting scientific research, they may be called oceanographers, marine biologists, or submersible pilots. In the context of deep-sea exploration, they might also be part of an expedition team. Submersible operators or scientists working with remotely operated vehicles (ROVs) may also fall into this category.
