Support for a U.S.-Taiwan Workshop on the Feedbacks Among Climate, Erosion and Tectonics

认识到气候调制侵蚀行为管理活动山脉的发展，可以说是板块构造革命之后地球科学中最具变革性的概念转变之一。构造活动区的地形是气候、构造和地表过程相互作用的结果。山脉的建造增加了地形坡度，直接影响侵蚀过程的速度和效率。上升的陆地也可以通过改变气流和加热模式来影响气候，从而影响降水的大小和模式。气候驱动的侵蚀造成的质量再分布之间的反馈可以影响应力状态、热结构和随后的山区变形模式，这些正是驱动地形增长的机制。然而，这些不同的相互作用和耦合的强度仍然存在争议。此外，这些过程对生活在山区的人类的福祉产生了强烈影响。该项目支持美国-台湾研讨会，将评估研究的现状，并确定未来的跨学科研究方向。该研讨会的一个主要目标是通过发展受益于两国研究专业知识的合作研究项目，加强美国和台湾之间的伙伴关系，从而加强每个国家的研究活动，同时促进对造山运动，气候和地表过程之间复杂联系的理解。学生和早期职业科学家参加研讨会将确保长期合作的发展，从科学劳动力发展和科学思想交流的角度来看，这是互利的。该项目支持美国科学家参加将于2017年在俄勒冈州州立大学举行的美国台湾研讨会。本次研讨会的总体目的是促进对造山、气候和地表过程之间的联系和反馈的跨学科研究。活跃的海岸和喀斯喀特山脉将在会前和会后的实地考察中进行探索，为讲习班提供背景。具体来说，研讨会的目标有四个方面：（1）评估目前的理解状态，在气候，造山运动和景观演化之间的反馈如何管理造山系统的轨迹;（2）确定和完善研究目标，利用跨学科的方法，这将导致我们对耦合的固体和流体地球系统的理解的下一组进展;（3）加强美国和台湾科学家之间正在出现的合作，并促进制定具体的研究战略，以实现研究目标;（4）扩大研究目标的范围，以包括台湾以外的系统，并增加更广泛的美国研究人员的参与。该研讨会围绕两个关键主题组织：该项目得到了构造计划和地貌学和土地利用动力学（均在地球科学司，地球科学理事会）以及NSF国际科学与工程办公室的支持。

The recognition that climatically modulated erosion acts to govern the development of active mountain ranges is arguably one of the most transformative conceptual shifts in the geosciences subsequent to the plate tectonic revolution. Topography in tectonically active regions results from an interplay among climatic, tectonic, and surface processes. The building of mountains increases topographic slopes, which directly influences the rate and efficiency of erosional processes. Rising landmasses can also influence climate by altering patterns of airflow and heating, influencing the magnitude and pattern of precipitation. Feedbacks between the redistribution of mass by climate-driven erosion can influence the state of stress, thermal structure, and subsequent deformation patterns within mountain belts, the very mechanisms that drive the growth of topography. The strength of these various interactions and coupling, however, is still contested. Furthermore, these processes have strong impacts on the well being of humans living in mountainous terrains. This project supports a U.S.-Taiwan workshop that would assess the current state of research and identify future interdisciplinary research directions. A key objective of the workshop is to increase partnerships between the U.S. and Taiwan through the development of collaborative research projects that benefit from research expertise in both countries, thereby strengthening research activities within each country while advancing understanding of the complex linkages among mountain building, climate, and surface processes. The participation of students and early-career scientists in the workshop will ensure the development of long-term collaborations that are mutually beneficial both from the perspective of the development of the scientific workforce and the exchange of scientific ideas. This project supports the participation of U.S. based scientists in a U.S. Taiwan workshop, which will be held at Oregon State University in 2017. The overarching purpose of this workshop is to promote interdisciplinary research on the linkages and feedbacks among mountain building, climate, and surface processes. The active Coast and Cascade Ranges, which will be explored during pre- and post-meeting field trips, will provide the backdrop for the workshop. Specifically, the workshop goals are four-fold: (1) evaluate the current state of understanding in how feedbacks among climate, mountain building, and landscape evolution govern the trajectory of orogenic systems; (2) identify and refine research goals that capitalize on transdisciplinary approaches that will lead to the next set of advances in our understanding of coupled solid and fluid earth systems; (3) strengthen emerging collaborations between U.S. and Taiwan scientists and to foster the development of specific research strategies to address research goals; and (4) broaden the scope of research goals to include systems beyond the Taiwan orogeny and to increase participation from a broader swath of U.S. researchers. The workshop is organized around two key themes: This project is supported by the Tectonics Program and the Geomorphology and Land Use Dynamics (both in the Earth Sciences Division, Geosciences Directorate) and NSF's Office of International Science and Engineering.
