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

PI建议测试一种新的声学多普勒海流剖面仪(ADCP)，该海流剖面仪首次有可能对Axial火山口上覆盖的整个~1500米水柱的海流进行实时监测。如果成功，该仪器将被社区广泛使用，其重要应用包括量化天然气水合物地点上升的甲烷和富含生物的羽流，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NSF的法定使命，并通过使用基金会的智力优势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.
