River-dominated Ocean Margins [RiOMar]: Workshop Management

河流是陆地和海洋环境之间的主要界面，在连接生物活性元素（特别是碳）的陆地和海洋循环中起着核心和多方面的作用。陆地上的风化和侵蚀过程、河流系统内的沉积物储存以及邻近海洋边缘的循环和掩埋过程的强度共同支持了河流和RiOMar环境在全球变化中发挥重要作用的前提。我们寻求支持在杜兰大学校园举行的社区研讨会（2001年秋季），大约50名来自地球和海洋科学界的科学家将参加。本次RiOMar研讨会的主要目标是：(1)评估河流及其相关边缘在全球碳和其他生物活性元素循环中的作用的现有知识状况。(2)通过社区共识，确定关于RiOMar环境及其在这些全球周期中的作用的主要未解决问题。突出的燃烧问题将被优先考虑，作为未来研究工作的重点。(3)确定需要跨学科和/或交叉研究方法的突出研究领域，并评估促进这些不同研究方法的方式。RiOMar的中心目标是评估河流和相关海洋边缘在全球碳循环和其他生物活性元素循环中的作用，并更好地表征这些环境中控制生物活性元素循环和命运的过程。

ABSTRACTRivers are the primary interface between terrestrial and ocean environments and play a central and multi-faceted role in linking the terrestrial and marine cycles of bioactive elements --- carbon in particular. The magnitude of weathering and erosion processes on land, sediment storage within the river system, and cycling and burial processes in adjacent ocean margins collectively support the premise that rivers and RiOMar environments play an important role in global change. We seek support for a community workshop, to be held on the Tulane University campus (Fall, 2001), in which approximately 50 scientists from the earth and ocean science communities will participate. Major goals to be addressed at this RiOMar workshop are: (1) To assess the current state-of-knowledge regarding the role of rivers and associated margins in the global cycles of carbon and other bioactive elements. (2) To identify, by community consensus, the major unresolved questions regarding RiOMar environments and their role in these global cycles. Outstanding iuburning questionslg will be prioritized as a means to focus future research efforts. (3) To identify salient areas of research in which interdisciplinary and/or cross-cutting research approaches will be needed, and to evaluate the manner in which these various research approaches can be facilitated.The central goal of RiOMar is to evaluate the role of rivers and associated ocean margins in the global cycles of carbon and other bioactive elements, and to better characterize the processes that govern the cycling and fate of bioactive elements in these environments.
