Question

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.
