The term 'ocean regions' can refer to a variety of different areas in the ocean, including DEEPS, which stands for Deep Ocean Exploration and Research Program. This program is an international effort to explore and research the deep ocean, which is defined as any area of the ocean that is deeper than 200 meters. The DEEPS program focuses on studying the physical, chemical, and biological processes that occur in the deep ocean, as well as the potential for mineral and energy resources.
