Explanation:

Submersibles are designed to operate in extreme ocean environments: they can withstand cold, high-pressure Arctic waters, access the deep ocean (which is unreachable by surface vessels), and while individual missions have costs, they eliminate the need for continuous surface support, reducing overall long-term ocean exploration expenses.
