Collaborative Research: Development of a Low-cost PHOtosynthesis, Respiration, and Carbon Balance Yielding System (PHORCYS)

PI申请资金用于开发一个名为PHORCYS（光合作用、呼吸作用和碳平衡生产系统）的原位孵化器。PHORCYS将包括开发一种简单、模块化、低成本的PHORCYS系统，该系统能够在原位部署的透明和不透明孵育室中进行高精度氧气测量；用于研究上部水柱初级生产的漂流阵列上的PHORCYS配置；PHORCYS配置与沉积物捕集器一起使用，以评估下沉颗粒呼吸速率；创建具有扩展功能的PHORCYS实验版本，可用于原位修正孵育实验；在沿海水域的短途巡航和前往公海的机会巡航中测试不同的配置；PHORCYS结果与其他技术所得结果的比较；建立一个独立的教育单位。目标是建立一个PHORCYS系统，该系统将被海洋学界广泛采用，并用于各种过程研究。更广泛的影响：这些仪器对海洋学界有很大的价值，因为它们相对便宜和便携，最终将允许广泛使用和世界范围内的相互比较。超越了硕士和博士的训练。本次活动将针对高中学生进行教育。PI长期致力于将海洋教育（例如海洋调查项目）扩展到社区以外的群体，这将在此次活动中得到进一步发展。鼓舞人心的年轻科学家对海洋的了解，既是招聘该领域的人才的工具，也是提高公众对科学和海洋知识的工具。

The PI's request funding to develop an in situ incubator called PHORCYS (PHOtosynthesis, Respiration, and Carbon balance Yielding System). PHORCYS will include development of a simple, modular, low-cost PHORCYS system capable of making high-precision oxygen measurements in clear and opaque incubation chambers deployed in situ; configuration of PHORCYS for use on a drifting array in order to study upper water column primary production; configuration of PHORCYS for use with sediment traps in order to assess sinking particle respiration rates; creation of an experimental version of PHORCYS with extended capabilities that can be used for in situ amendment incubation experiments; testing different configurations on short cruises in coastal waters and on cruises of opportunity to the open ocean; comparison of PHORCYS results with those collected using other techniques; and creation of a standalone unit for education. The goal is to create a PHORCYS system that will be widely adopted by the oceanographic community and used for a variety of process studies.Broader Impacts: These instruments would be of great value to the oceanographic community since they are relatively cheap and portable and would eventually permit widespread use and worldwide intercomparisons. Beyond the training of MSc and PhD. students this activity will target the education of high school students. The PI's have a successful long term commitment to broadening ocean education (e.g. the Ocean Inquiry project) to constituents outside the community and this will be furthered in this activity. Exciting young scientist about the ocean is both a vehicle of recruitment to the field as well as a vehicle to enhance science and ocean literacy in the greater public.
