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

拟议的工作涉及购买十 (10) 台新型高温（高温）深海热液喷口流体记录仪，供参与海洋观测计划 (OOI)、国际海洋发现计划 (IODP)、国家深潜设施 (NDSF) 和 NSF-EAR 研究计划的美国海洋学界科学家进行短期和长期部署。这些排放流体记录仪是由 PI 和 WHOI 工程师在过去 25 年中通过 WHOI-MISO 设施 (http://www.whoi.edu/miso) 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，以及增强对热液流动过程、与大洋中脊研究地点岩浆作用和构造作用的联系以及浅海地壳渗透性的理解的关键信息。新型 MISO 高温记录仪现由位于美国马萨诸塞州波卡塞特的海洋仪器公司 EP Oceanography, LLC (EPO) 制造，作为开发小型企业创新以及向私营部门转让海洋学研究所需的新技术和想法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.
