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

大陆表面沃茨代表了独特的环境，是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通道。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，对人类活动的影响高度敏感。如果没有来自有机化学和物理化学、生态系统科学、沉积学、景观演变、水-岩相互作用以及元素和物质循环（风化产物、微量元素、碳埋藏、养分通量、矿物颗粒等）等各种学科的数据，不可能对这些重要的地表水系统建立切实可行的模型，也不可能了解其各种物理和生物组成部分之间复杂的相互作用。填充这些模型所需的数据来自实地，实验，实验室和理论工作，涉及短期研究项目，长期研究观测站和水质监测系统。本次研讨会的目标是为一项重大的新的NSF数据和知识管理倡议（即，EarthCube），致力于通过提供对来自地球和环境科学的数据的轻松访问、发现和可视化来彻底改变地球科学。本次研讨会将汇集来自美国各地的约60名来自相关学科的地球科学家，包括网络/计算机科学专家，各方的联盟将共同确定这一重要竞技场的未来科学目标。它还将用于确定地表水和淡水生物地球化学问题工作者共同的最关键、最广泛的需求，并指导NSF EarthCube网络基础设施的开发。研讨会还将重点关注帮助科学家和他们需要跨越子学科障碍的数据的战略。讨论将涵盖实验，现场，地理空间和建模数据的各个方面，以及解决与定量分析和缩放方法，使观测的整合相关的问题。讲习班参加者还将讨论诸如沿沿着流动路径的处理率等专题，这些流动路径从沉积物-水界面等短尺度到大陆尺度流域。以跨学科的协调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领域取得变革性的进步。工作中心主要对科学基础设施建设产生更广泛的影响。

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.
