The Keys Marine Laboratory (http://keysmarinelab.org) is awarded a grant to upgrade and expand its existing seawater system to provide a state of the art research capability on-site. The Keys Marine Laboratory (KML), in the Florida Keys, is an educational and research laboratory serving researchers, faculty and students from around the world. This enhanced seawater system will provide KML users with year-round high quality, on-demand seawater to conduct laboratory experiments and hence allow on-site research not previously possible. The upgraded system provides the ability to recirculate and manipulate water quality, temperature, and pH into a variety of tanks, allowing for recirculation and effluent treatment, including filtration and UV sterilization. The proposal leverages prior improvements supported by the Florida Fish and Wildlife Conservation Commission (FWC). Water from the treatment facility (built with FWC funds), will flow into a series of head tanks where temperature and pH adjustments take place. A set of heaters and chillers provide temperature control and similarly, injected carbon dioxide regulates pH to desired levels. The head tanks then deliver water, via pumps, to the experimental tanks. The experimental tank setup will allow for experiments requiring replicate ability at varying volumes and a variety of temperature and pH combinations. Larger tanks will be equipped with the capacity for water recirculation. Recirculation allows for further control and manipulation of water, increased filtration, and provides a safeguard against upstream failures or contaminations. The new seawater system will provide a basis for research on tropical and sub-tropical ecosystems, including living marine resources, with global implications. In particular the ability to manipulate water quality to represent past, present, and future conditions will provide an improved scientific understanding and anticipation of the range of impacts to systems and living marine resources. In this way, forecasts can provide best case and worst case scenarios in addition to intermediate scenarios, which will guide resource management actions. For example, research on coral under future climate scenarios will provide new insights into coral productivity and vulnerability. It is estimated that coral reefs support a $4.4 billion industry in South Florida alone by providing a habitat for fishery resources for recreational and commercial fishing and through recreational snorkeling and diving activities. As such, they are not only of scientific curiosity, but are also of economic importance and a means of educational outreach to a broader audience.

海洋重点实验室（keysmarinelab.org）获得了一笔赠款，用于升级和扩大其现有的海水系统，以提供现场最先进的研究能力。凯斯海洋实验室（KML）位于佛罗里达凯斯，是一个教育和研究实验室，为来自世界各地的研究人员、教师和学生提供服务。这一增强的海水系统将为KML用户提供全年高质量的按需海水，以进行实验室实验，从而实现以前无法实现的现场研究。升级后的系统能够将水质、温度和pH值再循环和控制到各种水箱中，从而实现再循环和污水处理，包括过滤和紫外线灭菌。该提案利用了佛罗里达鱼类和野生动物保护委员会（FWC）支持的先前改进。来自处理设施（由FWC基金建造）的水将流入一系列高位水箱，在那里进行温度和pH值调节。一组加热器和冷却器提供温度控制，同样，注入的二氧化碳将pH值调节到所需水平。然后，高位水箱通过泵将水输送到实验水箱。实验罐设置将允许在不同体积和各种温度和pH组合下进行需要重复能力的实验。较大的水箱将配备水再循环能力。再循环允许进一步控制和操纵水，增加过滤，并提供对上游故障或污染的保护。新的海水系统将为研究热带和亚热带生态系统，包括具有全球影响的海洋生物资源提供基础。 特别是操纵水质以代表过去、现在和未来状况的能力，将提供对系统和海洋生物资源影响范围的更好的科学理解和预测。这样，预测可以提供最佳情况和最坏情况，以及指导资源管理行动的中间情况。 例如，在未来气候情景下对珊瑚进行研究，将为珊瑚的生产力和脆弱性提供新的见解。 据估计，仅在南佛罗里达，珊瑚礁就为休闲和商业捕鱼提供了渔业资源栖息地，并通过休闲浮潜和潜水活动，支持了价值44亿美元的产业。因此，它们不仅具有科学好奇心，而且具有经济重要性，是向更广泛的受众进行教育宣传的一种手段。
