项目摘要

The East Pacific Rise (EPR) is a fast-spreading mid-ocean ridge located in the eastern Pacific Ocean. It is part of a globe-encircling system of ridges where the crust of the Earth is created by the intrusion of melt from the deeper mantle and consequent volcanic eruptions. Hydrothermal vents from the MOR form chimneys and columns of metal-rich emissions as seawater flows through the oceanic crust. These hydrothermal processes alter the composition of oceanic lithosphere and the global ocean, and provide unique habitats for extreme forms of life in chemosynthetic ecosystems. Understanding the coupling between sub-surface flow patterns and crustal conditions is fundamentally important for virtually all fields of mid-ocean ridge and related geochemical and geophysical research. This research project focuses on the idea that a new magmatic event involving an eruption or shallow magma emplacement, is likely to happen at the EPR axis in the 9°50’N area in the next few years (~2020–2023). This forecast is based on observed increases in vent exit-fluid temperature, and chemical trends. The scientists at sea will employ the research submersible Alvin and/or remotely operated vehicle (ROV) Jason to deploy instruments and collect vent fluid samples during three cruises over three successive years to study these processes. The project also involves a collaboration between young investigators from the USA and Norway that will help strengthen international ties between researchers in both countries. The researchers will also create new teaching materials for the San Diego Unified School district via three workshops held at Scripps Institution of Oceanography. This collaboration with the San Diego County Office of Education will enhance their Environmental Literacy Initiative, and help to create a Next Generation Science Standards,activities and resources for middle and/or high school teachers in California and nation-wide.This project's research objective focuses on the idea that a new magmatic event, either an eruption or shallow dike emplacement, is likely to happen at the EPR axis in the 9°50’N area in the next few years (~2020–2023). This forecast is based on increases in vent exit-fluid temperature and chemical trends measured at hydrothermal vents. The build-up to this event is anticipated to be associated with changes in crustal dynamics that can be observed in the geochemical properties and thermal response to tidal forcing across multiple hydrothermal vents and their fluids. Specifically, the phase lag and amplitude ratio between the thermal response and loading signal can be used to track the run-up to the next volcanic eruption. In order to monitor the relationship between magma resupply and its impact on hydrothermal fluid flow, the project will apply numerical methods to exploit the tidal variability observed in exit-fluid temperature records acquired using self-recording high-temperature loggers. The result of this analysis will constrain poroelastic properties of the crust. To accomplish these goals, the project will collect several correlative datasets on three successive cruises spaced approximately 1-year apart, with seven Alvin or Jason ROV dives each year. The datasets include i) vent exit-fluid temperature records logged at ~15 min intervals; ii) annual fluid samples from each instrumented vent using isobaric gas-tight samplers; iii) tidal pressure and current strength data logged by moored sensors; iv) high-resolution still and 4k-resolution video imagery of vent structures that are instrumented, and v) baseline near-bottom bathymetry and sidescan dataset to be acquired in December 2019 using autonomous underwater vehicle Sentry. These data will be a key resource to underpin the work of geophysicists, biologists and chemists from across the mid-ocean ridge community working at EPR 9°50’N. eruption.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
东太平洋海隆(EPR)是位于东太平洋的一个快速扩张的洋中脊,它是环绕地球的海脊系统的一部分,地球的地壳是由更深的熔体侵入而形成的。当海水流过洋壳时,地幔和随后的火山喷发会形成烟囱和富含金属的排放柱。海洋岩石圈和全球海洋,并为化学合成生态系统中的极端生命形式提供独特的栖息地,了解地下流动模式与地壳条件之间的耦合对于洋中脊的几乎所有领域以及相关的地球化学和地球物理研究至关重要。该研究项目的重点是,未来几年内,北纬 9°50' 地区的 EPR 轴可能会发生涉及喷发或浅层岩浆侵位的新岩浆事件。 (~2020 年至 2023 年)。该预测基于观察到的出口流体温度上升和化学趋势,海上科学家将使用研究潜水器 Alvin 和/或遥控潜水器 (ROV) Jason 部署仪器并收集数据。该项目还涉及美国和挪威的年轻研究人员之间的合作,这将有助于加强两国研究人员之间的国际联系。圣地亚哥号联合学区通过在斯克里普斯海洋学研究所举办的三个研讨会与圣地亚哥县教育办公室合作将加强他们的环境素养计划,并帮助为初中和/或高中创建下一代科学标准、活动和资源。该项目的研究目标集中于这样一种观点,即未来几年内,北纬 9°50' 地区的 EPR 轴可能会发生新的岩浆事件,无论是喷发还是浅岩脉侵位。该预测基于热液喷口出口流体温度的增加和在热液喷口测量的化学趋势,预计该事件的发生与可观测到的地壳动力学变化有关。具体来说,多个热液喷口及其流体对潮汐强迫的地球化学特性和热响应,热响应和加载信号之间的相位滞后和振幅比可用于跟踪下一个火山的启动。为了监测岩浆补给及其对热液流动的影响之间的关系,该项目将应用数值方法来利用利用自记录高温记录仪获得的出口流体温度记录中观察到的潮汐变化的结果。该分析将限制地壳的孔隙弹性特性,为了实现这些目标,该项目将在间隔大约一年的连续三次航行中收集多个相关数据集,每次阿尔文或杰森 ROV 潜水七次。数据集包括 i) 以大约 15 分钟的间隔记录的通风口出口流体温度;ii) 使用等压气密采样器记录的每个通风口的年度流体样本;iv) 由系泊传感器记录的潮汐压力和水流强度数据; ) 已安装仪器的喷口结构的高分辨率静止图像和 4k 分辨率视频图像,以及 v) 将于 2019 年 12 月使用自主水下航行器获取基线近海底测深和侧扫数据集这些数据将成为支撑整个洋中脊社区在 EPR 9°50' 喷发工作的关键资源。该奖项反映了 NSF 的法定使命,并被认为是值得的。通过使用基金会的智力优势和更广泛的影响审查标准进行评估来提供支持。
