This project will, through the development of a sensor to measure the concentration of organic carbon dissolved in water, reveal information on the export of carbon from terrestrial landscapes to aquatic environments. At present, this understanding, generally constructed from grab samples, lacks detail. Dependent on sampling frequency, important periods of carbon export may remain undetected. Capturing detail, through high frequency in-situ measurement, will inform the calculation of accurate budgets of dissolved organic carbon export and provide insight into how the environment controls loss of carbon from the landscape. Such insights will offer societal and scientific advances in many ways, ranging from calculating how long for a windfarm takes to payback carbon expended in construction (construction may impact on terrestrial storage of carbon, later reflected in aquatic export), to incorporating rigourous models of how much carbon is transferred by rivers from land to sea, into global carbon cycle models. Accompanying development of the sensor to quantify DOC export will be contemporaneous characterisation of DOC composition by application of Raman spectroscopy. Should this approach prove viable, if time permits (ultimately dependent on student progress) the doctoral training programme will also explore development of field deployable sensors for logging of in-situ Raman spectra. On the short-term timescale (of this studentship), the research programme proposed will further our understanding of several NERC fundamental research priorities, namely, 'What are the sources, sinks and transportation processes of C within the earth system?', 'How is the carbon cycle influenced and integrated by other major biogeochemical cycles?', and thus is appropriate for NERC's key strategic and scientific priorities. However as the research programme will require training and expertise development across disciplines (biogeochemistry, statistical modelling and electronics), and this will be intellectually challenging, the longer term return from such NERC training investment is an intellectually flexible individual, positioned to address future emerging, inter-disciplinary research challenges. Indeed this doctoral training programme develops six of the fifteen key skills recently indentified as critical skill gaps for the environment sector (ERFF Report Number, Most Wanted Skill Needs in the Environment Sector), namely expertise in modelling (of time series), data management, numeracy, multi-disciplinarity, fieldwork and freshwater science.

该项目将通过开发传感器来测量溶解在水中的有机碳的浓度，揭示有关从地面景观出口到水生环境的碳的信息。目前，这种理解通常是由抢购样本构成的，缺乏细节。取决于采样频率，碳输出的重要时期可能仍未发现。通过高频原位测量捕获细节将为溶解有机碳出口的准确预算计算，并提供有关环境如何控制景观中碳损失的洞察力。这种见解将在许多方面提供社会和科学进步，包括计算风能需要多长时间的投资回收碳在建筑中消耗的碳（施工可能会影响碳的地面存储，后来反映在水上出口中），到结合河流从陆地转移到海上，将多少碳转移到全球碳循环模型中。伴随传感器来量化DOC导出的开发将是通过应用拉曼光谱法对DOC组成的同时表征。如果这种方法可行，如果时间许可（最终取决于学生的进步）博士培训计划还将探索可部署传感器的开发，以记录原地拉曼光谱。在短期时间尺度（该学生验证的）中，提出的研究计划将进一步理解地球系统中C中C的来源，下沉和运输过程是什么？”，“碳循环的来源，下沉和运输过程是什么？但是，由于研究计划将需要跨学科（生物地球化学，统计建模和电子设备）跨学科的培训和专业知识发展，这将在智力上具有挑战性，因此从这种NERC培训投资中获得的长期回报是一个智力灵活的人，定位于应对未来新兴的跨学科，跨学科的研究挑战。确实，该博士培训计划开发了最近将15个关键技能缩减为环境领域的关键技能差距（ERFF报告编号，环境领域中最想要的技能需求），即（时间序列），数据管理，算术，多学科，多学科，现场工作，现场工作和淡水科学方面的专业知识。
