摘　　要：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 novel self-contained benthic environmental observation system （called Benvir） for in-situ monitoring of the deep-sea benthic boundary layer was designed and implemented. The system has a modular, open architecture and a self-contained data storage, with the smaller size and air-weight compared to other in-situ benthic monitoring sys- tems. The Benvir can integrate a variety of sensors and devices for in-situ measurement, including chemical sensors of methane, CO2, dissolved oxygen （ DO）, pH, conductivity, etc. , and physical sensors of temperature, pres- sure, turbidity, as well as the acoustic Doppler current profile （ADCP） for measuring of flow velocity and the acoustic Doppler velocimeter （ADV） for measuring of turbulence, with the function of in-situ, continuous, and synchronous measurements in the water depth up to 4000m and the unique capability of profiling across the water- sediment interface. The Benvir is an effective tool for monitoring of the process of benthic methane seepage and study of biogeoehemical processes in the benthic boundary layer.
