ABSTRACTIntellectual MeritThis research is a pilot program to collect samples to test models of how the Pacific Plate is recycled through subduction at the deepest ocean trench, the Challenger Deep in the Mariana Trench, using the world's first full-ocean depth hybrid remotely operated vehicle (HROV). The work serves as a test of the scientific usefulness of the deep-diving robotic sampler by having it sample and return to the surface a wide variety of rock, fluid, and biological samples from the deepest part of the seafloor. Samples taken by the HROV will permit the composition of fluids driven off the Pacific Plate as it is subducted to be studied and interpreted in terms of how these fluids can be used to understand mineral reactions that affect the mantle and crustal rock overlying the subduction zone. Because fluids carry nutrients produced by reactions in the supra-subduction-zone mantle that fuel sub-seafloor communities of microorganisms and colonies of seafloor seep organisms, this work will also provide a picture of ecosystems associated with seeps at the world's deepest ocean trench. The work involves seafloor mapping by the HROV and using the HROV to take samples of rock, fluid, sediments, and organisms from the seafloor on the overriding tectonic plate in the Marianas Trench. The project will also produce one of the first video surveys of ecosystems that occur in these extremely high-pressure and chemically unique environments. Broader ImpactsThis research supports researchers at the University of Hawaii and at Woods Hole Oceanographic Institution in Massachusetts, one of which is a woman. The work helps to build capabilities of new oceanographic equipment that is capable of operating at the deepest depths in the ocean. Additional impacts are related to making the samples to be collected available to the wider scientific community.

知识产权这项研究是一个试点计划，收集样本，以测试太平洋板块是如何通过俯冲在最深的海沟，挑战者深在马里亚纳海沟，使用世界上第一个全海洋深度的混合远程操作的车辆（障碍）的模型。 这项工作是对深潜机器人取样器的科学用途的一次测试，它从海底最深处取样并将各种岩石、流体和生物样品送回地面。 由海卫二采集的样本将允许研究和解释太平洋板块俯冲时被驱出的流体的组成，这些流体如何用于理解影响俯冲带上的地幔和地壳岩石的矿物反应。 由于流体携带着俯冲带上地幔反应产生的营养物质，为海底下微生物群落和海底渗漏生物群落提供燃料，这项工作还将提供与世界上最深的海沟渗漏有关的生态系统的图片。 这项工作包括由海基号进行海底测绘，并利用海基号从马里亚纳海沟覆盖的构造板块上的海底采集岩石、流体、沉积物和生物样本。 该项目还将制作对这些极高压和化学独特环境中发生的生态系统的首批视频调查之一。 更广泛的影响这项研究支持夏威夷大学和马萨诸塞州的伍兹霍尔海洋研究所的研究人员，其中一名是女性。 这项工作有助于建立能够在海洋最深处工作的新海洋学设备的能力。 其他影响与向更广泛的科学界提供所收集的样本有关。
