Providing Self-recording Temperature and Attitude Loggers for Hydrothermal Vent Fluid Monitoring at Seafloor and Lacustrine Study Sites

拟议的工作包括购买十(10)台新型高温(高温)深海热液喷口流体记录仪，供参与海洋观测倡议(OOI)、国际海洋发现计划(IODP)、国家深海潜水设施(NDSF)和NSF-EAR研究计划的美国海洋学界科学家在短期和长期部署中使用。这些喷口流体记录仪是由PI和WHOI工程师通过WHOI-MISO设施(http://www.whoi.edu/miso).)在过去25年中开发和改进的这些仪器提供了大洋中脊(MOR)热液喷口流体温度的最长时间序列记录，并提供了关键信息，以加强对热液流动过程、与大洋中脊研究地点的岩浆活动和构造的联系以及浅海地壳渗透率的了解。新型MISO高频记录仪现在由EP Ocean，LLC(EPO)制造，EP Ocean，LLC(EPO)是一家位于美国马萨诸塞州波卡塞特的海洋仪器公司，作为开发小企业创新和将海洋研究所需的新技术和想法转移到私营部门的合作努力的一部分。

The proposed work involves purchase of ten (10), new model, high-temperature (high-T), deepsea hydrothermal vent fluid loggers for use in short- and long-term deployments by scientists in the US oceanographic community involved in Ocean Observing Initiative (OOI), International Ocean Discovery Program (IODP), National Deep Submergence Facility (NDSF) and NSF-EAR research programs. These vent fluid loggers have been developed and improved upon over the past 25 years by the PI and WHOI engineers through the WHOI-MISO Facility (http://www.whoi.edu/miso). These instruments have provided the longest time series records of mid-ocean ridge (MOR) hydrothermal vent fluid temperatures, and key information that enhances understanding of hydrothermal fluid flow processes, linkages to magmatism and tectonism at mid-ocean ridge study sites, and shallow ocean crustal permeability. The new model MISO high-T loggers are now manufactured by EP Oceanographic, LLC (EPO), an oceanographic instrumentation company in Pocasset, MA (USA), as part of a collaborative effort to develop small-business innovation and transfer new technologies and ideas needed for oceanographic research to the private sector.
