该研究项目的目标分为3个方面:1)利用海底微生物燃料电池(BMFC)将海底有机沉积物转化为能量,驱动水下仪器;2)通过声传输的方式,在海底缆接观测站或水面船只之间准实时接力回传水下仪器采集的数据;3)研究协同工作的水下系统在布放期间的工作性能。在加利福尼亚州蒙特利湾加速研究系统(MARS)观测站附近水域,研究人员布放了2组BMFC水下传感/通信设备。MARS为缆接式观测站,布设水深约890 m,距蒙特利湾海洋生物研究所(MBARI)约37 km。布放的传感器所采集的数据通过水声传输至MARS节点和水面调查船,证明了这项技术的实用性。
The objectives of this research project are divided into three aspects: 1) Transforming the organic sediments of the seafloor into energy by means of the BMFC, driving the underwater equipment; 2) By means of acoustic transmission, Data collected by submarine instruments should be transferred back and forth between surface vessels in real time. 3) The performance of underwater systems during deployment should be studied. Researchers deployed two BMFC subsea sensing / communications equipment at waters near the MARS observation station in Monterey Bay, California. MARS is a cable-connected observatory with a water depth of about 890 m, about 37 km from the Institute of Marine Biology at the Bay of Maville (MBARI). The data collected by the deployed sensors is transmitted underwater to the MARS node and the surface survey vessel, proving the practicality of this technique.
