US-Japan Joint Seminar on Responses of Catchment Hydrology and Forest Biogeochemistry to Climatic and Environmental Change

将举行一次美日水文学联合研讨会，以促进思想交流，弥合研究方法的差距，并共同制定未来的研究方向。从历史上看，两国科学家之间的互动有限，因为语言，文化和研究重点将这些科学界分开。这些差异突出了科学发现的潜力，也是这次美日水文联合研讨会的原因。即将举行的研讨会的目的是扩大水文学和地球化学联系的主题，以考虑气候和环境变化的影响，以及流域科学研究中使用的新兴测量和分析技术，从而实现基础科学的进步。会议将邀请来自每个国家的大约20名科学家，包括学生和早期职业科学家，在一个开放的论坛上介绍和讨论集水科学的前沿研究，以促进合作和交流。 研讨会将侧重于水文和地球化学流域科学的以下方面：（1）面对气候和环境变化，水文连通性在调节碳和氮循环以及流域输出方面的作用;（2）沿着气候梯度进行综合和跨地点比较，以了解流域溶质产量的机制;（3）平衡营养物收支和更好地了解各种过程（反硝化、运输、吸收、矿化等）的技术（示踪气体通量、同位素质量平衡）的进展;和（4）将实地观测与理论相结合，为更好的模型预测提供信息美日联合研讨会将1）促进美国和日本流域科学家之间的互动，并开发新的合作研究，2）激励和吸引下一代科学家，他们将成为研究的领导者，并支持两国未来的互动，（3）促进对集水区如何响应气候和环境变化的理解。跨大陆综合是一项挑战，但对于确定集水区将如何应对全球环境变化来说却是必要的。为了迎接这一挑战，拟议的集水水文学和森林生态地球化学多角度研讨会将汇集资深研究人员和早期职业科学家，为集水科学的综合提供宝贵的机会。

A US-Japan Joint Seminar in hydrology will be held has to foster exchange of ideas, bridge gaps in research approaches, and to jointly develop prospective research directions. Historically, there has been limited interaction among scientists between the two countries because language, culture, and research foci separate these scientific communities. These differences highlight a potential for scientific discovery and are the reasons for this US-Japan Joint Seminar in hydrology. The purpose of this forthcoming seminar is to expand the theme of linking hydrology and biogeochemistry to consider effects of climatic and environmental change, as well as emerging measurement and analytical techniques used in catchment science research that allow fundamental scientific advancements. The meeting will host approximately 20 scientists from each country, including students and early career scientists, to present and discuss cutting-edge research in catchment sciences in an open forum to foster collaboration and exchange. The seminar will focus on the following aspects of hydrological and biogeochemical catchment sciences: (1) the role of hydrologic connectivity in regulating carbon and nitrogen cycling and export from catchments in the face of climatic and environmental change; (2) synthesis and cross-site comparison along climatic gradients to understand mechanisms of solute yields from catchments; (3) advances in techniques (trace gas fluxes, isotopic mass balances) for balancing nutrient budgets and better understanding processes (denitrification, transport, uptake, mineralization, etc.); and (4) integrating field observations with theory to inform better model predictions The US-Japan Joint Seminar will 1) foster interaction and develop new collaborative research between US and Japanese catchment scientists, 2) stimulate and engage the next generation of scientists who will become leaders in research and support future interaction between the two countries, and 3) advance understanding of how catchments respond to climatic and environmental changes. Cross-continental synthesis is a challenge, yet a necessity for determining how catchments will respond to global environmental change. To meet that challenge, the proposed multi-perspective seminar in catchment hydrology and forest biogeochemistry will bring together established researchers and early career scientists, providing invaluable opportunities for synthesis in catchment sciences.
