Collaborative Research: An EarthCube Domain Workshop integrating the inland-waters biogeochemistry and fluvial sedimentology communities, April 22-24.

大陆地表水代表着独特的环境，是生物地球化学储存和转化的热点，也是大规模物质向海洋和大气输送的管道。这些系统是全球地球化学循环的组成部分，与人类健康和经济活动交织在一起，对人为影响高度敏感。没有来自各种学科的数据，如有机和物理化学、生态系统科学、沉积学、景观演化、水岩相互作用、元素和物质循环（风化产物、微量元素、碳埋藏、营养通量、矿物颗粒等），就不可能真实地模拟这些重要的地表水系统，也不可能理解它们的各种物理和生物成分之间的复杂相互作用。建立这种模型所需的数据来自实地、实验、实验室和理论工作，包括短期研究项目、长期研究观测和水质监测系统。本次研讨会的目标是提出河流和淡水生物地球化学研究领域的需求，以满足一项新的主要NSF数据和知识管理倡议（即EarthCube），该倡议致力于通过提供方便的访问、发现和可视化来自地球和环境科学的数据来彻底改变地球科学。本次研讨会将汇集约60名来自美国各地的地球科学家，他们来自相关学科，包括网络/计算机科学专家，这个各方联盟将有一个共同定义未来科学目标的工作在这个重要的领域。它还将用于确定地表水和淡水生物地球化学问题研究人员共有的最关键、最广泛的需求，并指导NSF EarthCube网络基础设施的发展。该研讨会还将侧重于帮助科学家和他们需要的数据跨越子学科障碍的策略。讨论将涵盖实验、原位、地理空间和建模数据的各个方面，并解决与定量分析和缩放方法相关的问题，从而实现观测的整合。讲习班参与者还将讨论诸如从沉积物-水界面等短尺度到大陆尺度盆地等流动路径上的过程速率等主题。以跨学科协调的方式解决这些需求的进展有可能在这个分散但关键的研究界交叉点带来变革性的进步。工作中心的广泛影响主要是为科学建设基础设施。

Continental surface waters represent distinct environments that are hot spots of biogeochemical storage and transformation, as well as conduits for large-scale material transport to the oceans and atmosphere. These systems are integral components of global geochemical cycles, are intertwined with human health and economic activity, and are highly sensitive to anthropogenic impacts. Without data from a wide variety of disciplines, such as organic and physical chemistry, ecosystem science, sedimentology, landscape evolution, water-rock interaction, and element and material cycles (weathering products, trace elements, carbon burial, nutrient fluxes, mineral particles, etc.), it is not possible to realistically model these important surface water systems and understand the complex interactions between their various physical and biological components. Data necessary to populate such models comes from field-based, experimental, laboratory, and theoretical work, involving short research projects, long-term research observatories, and water quality monitoring systems. The goal of this workshop is to surface requirements in the fields of river and fresh water biogeochemical studies for a major new NSF data and knowledge management initiative (i.e., EarthCube) that is dedicated to revolutionizing geoscience by providing easy access to, discovery of, and visualization of data from across the geo- and environmental sciences. This workshop will bring together ~60 geoscientists from across the US who come from relevant disciplines, including cyber/computer science experts, this coallition of parties will have a job to collectively define future science goals in this important arena. It will also be used to identify the most critical, widespread needs shared by those working on surface water and fresh water biogeochemical problems and to guide the development of NSF EarthCube cyberinfrastructure for this community. The workshop will also focus on strategies that help scientists and data that they need to cross sub-discipline barriers. Discussions will encompass all aspects of experimental, in-situ, geospatial, and modeling data as well as address issues related to quantitative analytical and scaling approaches that enable the integration of observations. Workshop participants will also address topics such as process rates along flow paths ranging from short scales such as sediment-water interfaces, to continental-scale basins. Progress addressing these needs in a coordinated fashion across sub-disciplines has the potential to lead to transformative advancements in this dispersed but critical intersection of research communities. Broader impacts of the work center primarily on building infrastructure for science.
