美国国家科学基金会海洋技术和跨学科协调（OTIC）计划资助了工程开发和连接声纳仪器包到位于Juan de Fuca Ridge北部的主要奋进场（MEF）的区域电缆天文台（RCO）的NEPTUNE加拿大阶段1组件的奋进节点，作为海洋观测站倡议（OOI，图1）的一部分。加拿大NEPTUNE RCO在MEF的主干电缆于2007年安装，节点于2008年安装，天文台于2009年开始运行。声纳系统将利用创新的声学成像方法监测海底热液流动，提供变化几何形状（大小、形状、方向、膨胀率、夹带率）和从矿化烟囱中喷出的黑烟浮力热液柱的流量（流量和体积通量）的时间序列测量。
The National Science Foundation Oceanographic Technology and Interdisciplinary Coordination (OTIC) program funded the engineering development and connection of the sonar instrument package to the Endeavor node of the NEPTUNE Canada Stage 1 component of the Regional Cabled Observatory (RCO) in the Main Endeavour Field (MEF) on the northern Juan de Fuca Ridge as part of the Ocean Observatories Initiative (OOI, Figure 1). The backbone cable of the NEPTUNE Canada RCO in the MEF was installed in 2007, the node was installed in 2008, and the observatory began operation in 2009. The sonar system will monitor seafloor hydrothermal flow using innovative acoustic imaging methods to provide time series measurements of changing geometry (size, shape, orientation, expansion rate, entrainment rate) and discharge (flow rate and volume flux) of buoyant hydrothermal plumes of black smokers venting from mineralized chimneys.
