A Phased Engineering Program to Build a New 6500-M Research Submersible for the U.S. Scientific Community: The New Alvin

研究机构：WHOIProposal #: 0433409WHOI提议为美国海洋学界设计和建造一个新的，最先进的6500米深潜水研究载人车辆（HOV），以取代DSV Alvin。通过提供常规进入深海海底并进行观测、采样和测绘研究的能力，DSV Alvin在过去四十年中帮助彻底改变了我们对海底地质过程和底栖生态系统的理解，在塑造我们星球的生物、化学和地质过程方面取得了重要发现。拟议的HOV替代品将是一种更强大、技术更先进的深潜器，并且只需要对船体进行一些修改，就可以在R/V亚特兰蒂斯上操作。设计中提出的科学元素包括许多尖端技术，例如允许中水柱研究的可变压载系统，使用新的电池系统来增加海底时间和深度能力，以达到海底的95%。这些独特技术的实施将增强科学用户的能力，并扩展能够使用深潜器进行研究的海洋学学科套件

Principal Investigator: Barrie WaldenInstitution: WHOIProposal #: 0433409WHOI proposes to design and build a new, state-of-the-art 6500 meter deep submergence research human occupied vehicle (HOV) for the U.S. oceanographic community to replace the DSV Alvin. By providing the capability to routinely access the deep seafloor and conduct observational, sampling and mapping studies, DSV Alvin has, over the past four decades, helped to revolutionize our understanding of seafloor geologic processes and benthic ecosystems, making important discoveries about the biological, chemical and geological processes that shape our planet. The proposed HOV replacement will be a more robust and technologically advanced deep submergence vehicle, and will still be capable of operating off of the R/V Atlantis with only minor ship modifications. Proposed scientific elements of the design include many cutting edge technologies, such as a variable ballast system to allow for midwater column research, use of new battery systems to increase bottom time and depth capability to reach 95 per cent of the ocean bottom. Implementation of these unique technologies will allow science users enhanced capabilities and expand the suite of oceanographic disciplines that will be able to use a deep submersible for research.***
