项目摘要
Due to the difficulty in working in the deep sea, especially around high-termperature hydrothermal vents that belch hot, corrosive, metal-rich fluids into ocean, novel instumentation needs to be developed and tested so important thermal and chemical fluxes associated with these systems can be determined. This research involves the testing, implementation, and data recovery from a unique acoustic sonar system (COVIS) that uses acoustic sonar and doppler phase shifts to make quantitative measurements of hydrothermal vent plume rise rates, volume fluxes, and plume shapes and distributions with time. Software will also be generated to enable processing of the resulting data and the extraction of heat fluxes, both in the plume emmanating from the hydrothermal vent and its rising thermal plume and from the diffuse flow of hot water along the seafloor around the vent. Field testing will occur at the Grotto hydrothermal vent cluster at the Endeavor vent field on the Juan de Fuca Ridge which is presently part of the Canadian mid-ocean ridge monitoring station. Resulting quantitative acoustic images of the plumes will be used to generate seafloor heat flux values that are fundamental to understanding the dynamics of hydrothermal venting. Three dimensional images of the hydrothermal plumes coming from the Grotto vents will also be generated. Project goals include determining linkages between time-varying flow measurements on the seafloor and fluxes higher in the water column. Broader impacts of the work include building infrastructure for oceanographic science in terms of developing hardware and software that will complement and potentially be implemented on NSF's newly installed Ocean Observing System infrastructure at the vent fields at Axial Volcano on the Juan de Fuca Ridge, which is slated to be instrumented in 2013. Additional impacts include international collaboration with Canadian scientists, support of an institution in an EPSCoR state (New Jersey), support of two PIs from groups under-represented in the sciences, training of graduate and undergraduate students, and public outreach through the NEPTUNE Canada and NOAA outreach engines.
由于在深海工作的困难,特别是在高温热液喷口周围,这些喷口将热的,腐蚀性的,富含金属的流体喷入海洋,因此需要开发和测试新的仪器,以便确定与这些系统相关的重要热和化学通量。这项研究涉及测试,实施和数据恢复,从一个独特的声学声纳系统(COVIS),使用声学声纳和多普勒相移进行定量测量热液喷口羽流上升速率,体积通量,羽流形状和分布随时间的变化。还将制作软件,以便能够处理由此产生的数据,并提取热通量,包括热液喷口及其上升热羽流发出的羽流以及喷口周围沿着海底的热水扩散流。将在胡安·德富卡海脊奋进喷口区的格罗托热液喷口群进行实地测试,该海脊目前是加拿大大洋中脊监测站的一部分。由此产生的羽流定量声学图像将用于生成海底热通量值,这些值对于了解热液喷发动态至关重要。还将生成来自石窟喷口的热液羽流的三维图像。项目目标包括确定海底随时间变化的流量测量与水柱高处的通量之间的联系。这项工作的更广泛影响包括建设海洋科学基础设施,开发硬件和软件,以补充国家科学基金会新安装的海洋观测系统基础设施,并有可能在该系统基础设施上实施,该系统位于胡安·德富卡海岭的轴向火山喷口区,定于2013年安装仪器。其他影响包括与加拿大科学家的国际合作,支持EPSCoR州(新泽西)的一个机构,支持科学领域代表性不足的两个PI,培训研究生和本科生,以及通过NEPTUNE Canada和NOAA外展引擎进行公众宣传。
