An Autonomous Bottom-Transecting Instrument for Making Long Time-Series Measurements of Phytopigment Fluorescence & Acoustically Detectable Sediment Structure to Abyssal De

9732353史密斯克里普斯海洋学研究所将继续开发深海自主航行器的能力，这将为海洋科学界感兴趣的各种传感器提供平台。这项建议建立在罗孚汽车开发过程中的工作和经验的基础上。该项目涉及开发先进的Rover II，对仪器组装和有效载荷配置进行了重大修改，以适应光声成像系统和顺序多取心系统。这些新的传感和采样系统还需要修改中央控制器组件。Rover II被设想为一种自主的海底横断面仪，用于对植物膜荧光和可声探测的沉积物结构进行时间序列测量。这一工具解决了海洋生物地球化学家和底栖生物学家广泛关注和关注的问题。对底栖生物群落对脉冲颗粒有机质(POM)输送的响应以及由此产生的有机质在表层沉积物中的分布和去向的时间序列测量，对于我们理解底栖-远洋耦合在整个盆地化学循环收支中的作用至关重要。

9732353 Smith Scripps Institution of Oceanography will continue development of a deep sea autonomous vehicle (AUV) capability that will provide a platform for a variety of sensors of interest to the ocean science community. This proposal builds on the work and experience gained during development of the ROVER vehicle. The project involves development of an advanced ROVER II, with major modifications in the instrument assembly and payload configuration to accommodate an optical acoustic imaging system and a sequential multiple coring system. These new sensing and sampling systems also will require modification of the central controller package. ROVER II is envisioned to be an autonomous bottom-transecting instrument for making time-series measurements of phytopigmnet fluorescence and acoustically detectable sediment structure. This vehicle addresses questions of significant interest and concern to a broad spectrum of marine biogeochemists and benthic biologists. Time-series measurements of the responses of benthic communities to pulsed Particulate Organic Matter (POM) delivery, and the resultant distribution and fate of organic matter within surface sediments, is critical to our understanding of the role of benthic-pelagic coupling in basin- wide chemical cycling budgets.
