RAPID: OOI-Industry Partnership to Install a Cabled 45 kHz ADCP at Axial Seamount Caldera

PI提议测试一种新的声学多普勒电流分析器（ADCP），该仪器首次有可能提供覆盖在轴向火山口上的整个约1500米水柱的实时电流监测。如果成功，该仪器将广泛应用于社区，重要的应用包括量化天然气水合物处不断上升的富含甲烷和生物的羽流，以及监测受海洋酸化和缺氧事件影响的大陆边缘洋流的变化。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The PI proposes to test a new acoustic Doppler current profiler (ADCP) which has the potential, for the first time, to provide real-time monitoring of currents throughout the entire ~1500 m of water column that overlies Axial caldera. If successful, this instrument will be of broad use to the community with important applications spanning quantification of rising methane-and biologically-rich plumes at sites of gas hydrates, to monitoring changes in currents along continental margins impacted by ocean acidification and anoxia events.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.
