The world's oceans below 6,500 meters are presently virtually unexplored. Thesediverse and inaccessible tectonic regimes pose significant questions about a wide range of fundamental problems in the earth and ocean sciences. These regimes include deep areas of active continental margins where major earthquakes are generated and hydrologic exchange occurs between subducted oceanic lithosphere and island arc complexes. Deep access to the seafloor in areas of ultra-slow spreading mid ocean ridges, primarily found in geographic regions of inhospitable weather or ice covered ocean (e.g. Arctic), would be a primary use for such a vehicle. The capability to routinely access the deepest ocean depths also has important implications for a broad range of science and engineering associated with ocean observatory and event response research that will explore 3D and 4D multidisciplinary problems for decades to come. Hybrid ROVs will enable the scientific community to quickly react to ocean floor volcanic and hydrothermal events from a wide range of UNOLS vessels, whereby follow-on experimentscan be designed and implemented based on detailed, first-order mapping and sampling conducted by the 11,000 meter HROV. Moreover, the HROV will provide the United States with fully global capability for search, survey, and recovery missions of national strategic importance.***

世界上 6,500 米以下的海洋目前几乎尚未开发。这些多样化且难以接近的构造体系对地球和海洋科学中的广泛基本问题提出了重大问题。这些区域包括活动大陆边缘的深层区域，那里会产生大地震，俯冲海洋岩石圈和岛弧复合体之间会发生水文交换。这种车辆的主要用途是深入进入超缓慢扩张的洋中脊区域的海底，这些区域主要存在于恶劣天气或冰雪覆盖的海洋（例如北极）的地理区域。定期进入最深海洋深度的能力对于与海洋观测和事件响应研究相关的广泛科学和工程也具有重要影响，这些研究将在未来几十年内探索 3D 和 4D 多学科问题。混合 ROV 将使科学界能够通过各种 UNOLS 船只对海底火山和热液事件做出快速反应，从而可以根据 11,000 米 HROV 进行的详细的一阶测绘和采样来设计和实施后续实验。此外，HROV 将为美国提供全面的全球能力，以执行具有国家战略重要性的搜索、调查和回收任务。***
