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

PI要求提供资金，以开发一种名为PHORCYS(光合作用、呼吸作用和碳平衡产生系统)的原位孵化器。PHORCYS将包括开发一个简单、模块化、低成本的PHORCYS系统，该系统能够在现场安装的清澈不透明的孵化箱中进行高精度的氧测量；PHORCYS系统的配置用于漂流阵列，以研究上层水柱的初级生产力；PHORCYS系统的配置，用于与沉积物捕捉器一起使用，以评估下沉颗粒呼吸率；创建一个实验版本，其功能扩大，可用于现场修正孵化实验；在沿海水域的短途航行和前往公海的机会邮轮上测试不同的配置；将PHORCYS系统的结果与使用其他技术收集的结果进行比较；创建一个独立的教育单位。目标是创建一个将被海洋学社区广泛采用并用于各种过程研究的PHORCYS系统。广泛影响：这些仪器对海洋学社区将非常有价值，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。不只是硕士和博士的训练。学生这项活动将针对高中生的教育。国际海洋研究所成功地长期致力于将海洋教育(例如海洋调查项目)扩大到社区以外的成员，并将在这次活动中进一步推动这一点。关于海洋的激动人心的青年科学家既是招募到该领域的工具，也是提高广大公众的科学和海洋素养的工具。

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.
