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，该实验室是位于弗朗西斯科以北70英里的索诺马海岸的加州大学戴维斯分校的研究单位。实验室现有的海水系统包括海水取水口、泵房、储罐、处理系统以及通往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、消毒、温度调节、曝气和混合等要素。 BML的常驻和访问科学家对海水的研究需求的增长已经使现有系统的容量不堪重负，该系统现在存在过饱和，生物污染以及过滤，温度控制和灭菌不足的问题。 由该合同资助的改进将包括增加进水管;增加泵送能力;一个新的大型海水澄清器，通过重力引起的颗粒沉降和过滤介质撞击进行脱气、过滤和澄清;使用两阶段臭氧和氯工艺对离开海洋病理学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却器容量;以及系统的计算机化控制的扩展。BML位于博德加海洋保护区（BMR）内;这是一个占地362英亩的保护区，拥有各种海洋和陆地沿海栖息地。邻近的潮下带地区受到保护，可在博德加海洋生物保护区内进行研究。 该实验室为在实验室建筑附近对丰富的植物群和动物群进行实地和实验室研究提供了机会。BML拥有设备齐全的实验室，强大的现场支持人员和加州大学戴维斯分校校园的坚定承诺，继续开发越来越多的居民和访问研究人员所需的设施和支持。BML居民和访问科学家对海水的研究需求增长，使现有系统的容量增加，该系统也存在过饱和，生物污染和过滤不足的问题，温度控制和灭菌。 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水管;增加泵送能力;一个新的大型海水澄清器，通过重力引起的颗粒沉降和过滤介质撞击进行脱气、过滤和澄清;使用两阶段臭氧和氯工艺对离开海洋病理学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却器容量;以及BML监控网络的扩展。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，并将提供研究人员使用BML网络和互联网远程监控单个实验室中生命支持系统的选项。

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.
