Carbon is the seminal element of life and environment. Much is known about the forms, fluxes and geochemical pathways of carbon in surface reservoirs. Much less is known about carbon in the largest Earth reservoir, the Earth's interior (crust, mantle and core). This reservoir, through chemical geodynamic pathways into and out of the interior, has exerted the major control on the surficial form and budget of carbon through deep geological time (i.e. the Hadean to the present). Yet huge gaps in our knowledge exist in understanding the deep carbon reservoir and its relationship to the surface environment. In this proposal we will explore the potential for an NERC Programme to fund a directed research effort into the relationship between the deep carbon cycle and the Earth's surface - we call this Carbon Geodynamics. We will also explore the possibility of developing a program of carbon research to compliment the research objectives of the Deep Carbon Observatory (DCO). This program, funded privately by the Sloan Foundation and managed through the auspices of the Carnegie Institution of Washington (USA) is a "multidisciplinary, international initiative dedicated to achieving a transformational understanding of Earth's deep carbon cycle". The scoping study will centre on a 3-day workshop where a group of UK primary stakeholders (~20), together with members of the DCO (~4) and a select set of international advisors (~6), will discuss the best strategy for such a UK Programme.

碳是生活和环境的开创性元素。关于表面储层中碳的形式，通量和地球化学途径知之甚少。关于最大的地球储层，地球内部（地壳，地幔和核心），对碳的了解少得多。该储层通过化学地球动力学途径进入内部，通过深层地质时代（即Hadean到现在）对碳的表面形式和预算进行了主要控制。然而，我们知识的巨大差距在理解深碳储层及其与表面环境的关系中存在。在此提案中，我们将探索NEC计划的潜力，以为深碳循环与地球表面之间的关系提供指示研究工作 - 我们称之为碳地球动力学。我们还将探讨制定碳研究计划以补充深碳天文台（DCO）的研究目标的可能性。该计划由斯隆基金会私人资助，并通过华盛顿卡内基学会（美国）的主持人进行了管理，这是一项“多学科的国际倡议，致力于实现对地球深碳周期的变革理解”。范围研究将集中在为期3天的研讨会上，其中一组英国主要利益相关者（〜20）与DCO（〜4）的成员以及一组精选的国际顾问（〜6）一起讨论了此类英国计划的最佳策略。
