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.

PI申请资助开发一个名为PHORCYS（光合作用、呼吸和碳平衡产生系统）的原位培养箱。PHORCYS将包括开发一个简单、模块化、低成本的PHORCYS系统，该系统能够在现场部署的透明和不透明的培养室中进行高精度的氧气测量;配置PHORCYS系统，用于漂流阵列，以研究上层水柱初级生产;配置PHORCYS系统，用于沉积物收集器，以评估下沉颗粒呼吸率;建立一个具有扩大能力的PHORCYS实验版，可用于原地修正孵化实验;在沿海沃茨的短途航行和在公海的机会航行中测试不同的配置;将PHORCYS结果与使用其他技术收集的结果进行比较;并建立一个独立的教育单位。目标是创建一个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将有很大价值，因为它们相对便宜，便于携带，最终可广泛使用，并可在全世界范围内进行相互比较。除了MSc和PhD的培训。学生这项活动将针对高中生的教育。PI的有一个成功的长期承诺，扩大海洋教育（如海洋调查项目），以社区以外的选民，这将进一步在这项活动。激发年轻科学家对海洋的兴趣既是招募该领域的工具，也是提高公众科学和海洋素养的工具。
