How was Jason 2 and Medea the submarines were used to explore the ocean?

Jason 2 and Medea are advanced submarines used for ocean exploration and research. Jason 2, an remotely operated vehicle (ROV), is equipped with high-definition cameras and various scientific instruments, allowing researchers to study deep-sea environments and marine life in real-time. Medea, a manned submersible, enables scientists to dive deeper into the ocean, facilitating hands-on research and direct observation of underwater ecosystems. Together, they have contributed significantly to our understanding of oceanic processes and biodiversity.
