项目摘要

In this project the researchers plan to develop a novel, new sensor package capable of measuring rates of aquatic carbon cycling. In the coastal and open ocean, rates of carbon cycling processes are not completely understood. This project will pave the way for future full-scale development of the sensor package that could substantially improve our confidence in the marine carbon cycle measurements and predictions for how the ocean may respond to human stressors in the future. The proposed work will advance the careers of two early career scientists. In addition, they plan to recruit undergraduate students through the Woods Hole Oceanographic Institution Summer Student Fellow Program, the semester at WHOI program, and the Woods Hole Partnership ProgramThe PIs will develop a prototype sensor package to resolve technical challenges and conduct preliminary tests of the quantification of photosynthesis rates, bacterial respiration rates and quotients, and photochemical oxidation rates and quotients. The focus of this EAGER proposal will be on overcoming critical technical challenges in order to develop this prototype. The development work proposed will pave the road for future development and testing of a full-scale, deployable in-situ device. If successful they will develop a prototype of a first of its kind to sensing system to simultaneously measure the in-situ rates of photosynthesis, microbial respiration, and photochemical oxidation in any surface water. The risk areas are in the pumping and plumbing systems and mitigation of biofouling. They have been working on a number of ways to resolve these issues but will have to do a lot of testing to see what works best.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在这个项目中，研究人员计划开发一种能够测量水生碳循环速率的新型传感器套件。在沿海和开阔的海洋中，碳循环过程的速率尚未完全了解。该项目将为未来传感器包的全面开发铺平道路，这将大大提高我们对海洋碳循环测量和预测海洋未来如何应对人类压力的信心。这项提议的工作将推动两位早期职业科学家的事业。此外，他们计划通过伍兹霍尔海洋研究所暑期学生研究员计划、WHOI计划学期和伍兹霍尔合作伙伴计划招收本科生。pi将开发一个原型传感器包，以解决技术挑战，并对光合作用速率、细菌呼吸速率和商数、光化学氧化速率和商数进行量化的初步测试。这个EAGER提案的重点是克服关键的技术挑战，以开发这个原型。拟议的开发工作将为未来开发和测试全尺寸、可部署的原位设备铺平道路。如果成功，他们将开发出同类传感系统的第一个原型，以同时测量任何地表水的光合作用，微生物呼吸和光化学氧化的原位速率。风险区域在抽水和管道系统以及减轻生物污染。他们一直在研究解决这些问题的多种方法，但还需要进行大量的测试，看看哪种方法最有效。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
