研制了一个可移动的自容式深海海底边界层原位监测装置(简称Benvir)。该装置采用模块化、开放式结构设计,自容式数据存储,较国际上其它海底原位监测装置具有较小的体积和空气重量,最大工作水深4000m。Benvir可集成一系列原位环境监测传感器,包括监测甲烷、二氧化碳、溶解氧、pH、电导率的化学传感器和监测温度、压力、浊度的物理传感器以及测量流速的声学多普勒流速剖面仪(ADCP)和测量湍流的声学多普勒流仪(ADV),具备近海底边界层多环境参数的原位、定点、连续和同步观测,以及近海底微尺度剖面的监测功能。Benvir在观测海底冷泉活动与甲烷渗漏过程和进行海底界面生物地球化学研究方面具有良好的应用前景。
A movable self-contained deep sea bottom boundary layer in-situ monitoring device (Benvir for short) was developed. The device uses a modular, open structure design, self-contained data storage, compared with other international seabed in situ monitoring device has a smaller volume and air weight, the maximum working depth of 4000m. Benvir can integrate a series of in situ environmental monitoring sensors including chemical sensors to monitor methane, carbon dioxide, dissolved oxygen, pH, conductivity and physical sensors to monitor temperature, pressure, turbidity and acoustic Doppler flow velocity profiler to measure flow rate ADCP) and Acoustic Doppler Flow Meters (ADVs) for measuring turbulence with in situ, fixed-point, continuous and simultaneous observations of multi-environmental parameters in the near-sea boundary layer and the monitoring capabilities of the near-sea micro-scale profiles. Benvir has good application prospects in the observation of seafloor cold spring activities and methane seepage process and the biogeochemical research of the seafloor interface.
