FSML: Seawater System Upgrade for Bodega Marine Laboratory

该奖项为博德加海洋实验室(BML)的海水系统改进提供支持，该实验室是加州大学戴维斯分校的一个研究单位，位于旧金山以北70英里的索诺马海岸。该实验室现有的海水系统包括海水进水口、泵房、储水罐、处理系统，以及通往整个BML数十个实验室的运输和分配线路网络。海水系统包括过滤、杀菌、温度调节、通风和混合等要素。BML常驻和来访的科学家对海水的研究需求不断增长，使现有系统的处理能力捉襟见肘，目前该系统存在过饱和、生物污垢以及过滤、温度控制和灭菌不足等问题。获得该奖项的改进将包括增加进水口；增加抽水能力；采用重力诱导颗粒沉降和过滤介质撞击进行脱气、过滤和澄清的新型大型海水净化器；使用两级臭氧和氯气工艺对离开海洋病理实验室的海水进行消毒的消毒升级；增加用于温度控制的冷冻机能力；以及扩大对系统的计算机控制。BML位于博德加海洋保护区(BMR)内；这是一个362英亩的受保护野外地点，拥有各种海洋和陆地沿海栖息地。邻近的潮下区域受到保护，可在博德加海洋生物保护区内进行研究。该实验室为实地和实验室研究靠近实验室大楼的丰富动植物提供了机会。BML拥有设备齐全的实验室、强大的现场支持人员以及加州大学戴维斯分校校区的坚定承诺，将继续开发越来越多的常驻和访问研究人员所需的设施和支持。BML常驻和访问科学家对海水的研究需求不断增长，使目前系统的处理能力陷入僵局，该系统还存在过饱和、生物污垢以及过滤、温度控制和灭菌不足等问题。该合同将使BML能够大幅扩展和升级海水系统，以满足当前和未来的需求。这些变化将包括增加进气管道；增加抽水能力；一个新的大型海水净化器，采用重力诱导颗粒沉降和过滤介质撞击的脱气、过滤和澄清；使用两级臭氧和氯气工艺对离开海洋病理实验室的海水进行灭菌升级；增加用于温度控制的冷风机能力；以及扩大BML的监测/控制网络。最后一个要素将简化日常维护，提高可靠性，并提供远程故障排除和控制，并将为研究人员使用BML网络和互联网远程监控各个实验室的生命支持系统提供选项。

This award provides support for the improvement of the seawater system at the Bodega Marine Laboratory (BML), a research unit of the University of California at Davis located on the Sonoma coast 70 miles north of San Francisco. The laboratory's existing seawater system consists of a seawater intake, pumphouse, storage tanks, treatment systems, and a network of transport and distribution lines to dozens of labs throughout BML. The seawater system incorporates elements of filtration, sterilization, temperature conditioning, aeration and mixing. Growth in research demand for seawater from resident and visiting scientists at BML has taxed the capacity of the present system, which now suffers from problems with supersaturation, biofouling, and insufficient filtration, temperature control and sterilization. Improvements aided by the award will include additional intake lines; increased pumping capacity; a new, large, Seawater Clarifier employing degassing, filtration and clarification through gravity-induced particle settlement and filtration media impaction; a sterilization upgrade using two-stage ozone and chlorine processes to sterilize seawater leaving the marine pathology lab; an increase in chiller capacity for temperature control; and an expansion of the computerized control of the system. The BML lies within the Bodega Marine Reserve (BMR); a 362-acre protected field site with a diverse set of marine and terrestrial coastal habitats. Adjacent subtidal areas are protected and available for study within the Bodega Marine Life Refuge. The laboratory provides opportunities for field and laboratory research on a rich flora and fauna in close proximity to the Laboratory buildings. BML has well-equipped laboratories, strong on-site support staff and a firm commitment from the UC Davis campus to continue developing the facilities and support needed by the growing number of resident and visiting researchersGrowth in research demand for seawater from resident and visiting scientists at BML hastaxed the capacity of the present system, which also suffers from problems with supersaturation, biofouling, and insufficient filtration, temperature control and sterilization. This award will allow BML to significantly expand and upgrade the seawater system to meet current and future needs. These changes will include additional intake lines; increased pumping capacity; a new, large, Seawater Clarifier employing degassing, filtration and clarification through gravity-induced particle settlement and filtration media impaction; a sterilization upgrade using two-stage ozone and chlorine processes to sterilize seawater leaving the marine pathology lab; an increase in chiller capacity for temperature control; and an expansion of BML's Monitoring/Control Network. This last element will simplify routine maintenance, increase reliability, and provide remote trouble-shooting and control, and will provide options for remote monitoring of Life Support Systems in individual labs by researchers using the BML network and the Internet.
