This project supports a workshop in April 2019 at the Flathead Lake Biological Station (Montana) involving researchers from the United States of America and China. The cryosphere is the frozen part of the Earth and involves glacier ice, snowpack, and permafrost. Around the world, cryosphere melt is accelerating, including in mountain regions. These changes are important because mountain regions supply water to 40% of the world's population. However, in many situations it is not well-understood how the changing cryosphere impacts aquatic ecosystems such as lakes and rivers and the organisms that live in them. Furthermore, research conducted in different countries is often not well-integrated and data platforms for sharing of similar data are not well-developed. This workshop will support a 5-day meeting of researchers from the USA and China who are studying how the changing cryosphere affects aquatic ecosystems in mountain regions. An emphasis will be on how underlying biological similarities (Rules of Life) can help draw connections between regions and how data platforms can be developed to maximize efficiency and effectiveness in scientific investigations of these changes. This workshop will involve about 20 USA researchers at a broad range of career stages (graduate students to professors) and a similar cohort of Chinese counterparts. Mountain regions are experiencing rapid transitions in the cryosphere, losing permanent snow and ice that buffer discharge, shape regional environmental and habitat conditions, and provide diverse ecosystem services for humanity. The ongoing changes in the cryosphere are widespread, complex, and affect a variety of key parameters of alpine lakes and streams such as temperature, transparency, discharge, and nutrient supply. Documenting, understanding, and forecasting these impacts is challenging and requires broad interdisciplinary collaborations. Building off of the success of a first workshop held at Qinghai Lake in China in August 2017, a second workshop to be held in the USA has two goals: 1. assessing how fundamental similarities in biota (such as the temperature dependence of metabolism or the stoichiometric signature of biomass) can help understand the impacts of cryosphere loss on aquatic ecosystems and 2. establishing a framework for US/China joint data centers, producing a database across multiple sites in both countries. This workshop will foster international cooperation via collaboration across US and Chinese researchers working on a common, pressing environmental issue in both regions, establishing conceptual frameworks and building precedents for data sharing and collaboration. The highly interdisciplinary nature of the collaboration workshop will also provide important professional development opportunities and training for participants of all career stages including graduate students and postdocs.

该项目支持 2019 年 4 月在弗拉特黑德湖生物站（蒙大拿州）举办的研讨会，参与者包括来自美国和中国的研究人员。冰冻圈是地球的冰冻部分，包括冰川冰、积雪和永久冻土。在世界各地，冰冻圈融化正在加速，包括山区。 这些变化非常重要，因为山区为世界 40% 的人口供水。 然而，在许多情况下，人们并不清楚冰冻圈的变化如何影响湖泊和河流等水生生态系统以及生活在其中的生物。此外，在不同国家进行的研究往往没有很好地整合，用于共享类似数据的数据平台也没有得到很好的开发。该研讨会将支持来自美国和中国的研究人员举行为期 5 天的会议，他们正在研究冰冻圈的变化如何影响山区的水生生态系统。 重点将放在潜在的生物相似性（生命规则）如何帮助建立区域之间的联系以及如何开发数据平台以最大限度地提高对这些变化的科学研究的效率和有效性。本次研讨会将有大约 20 名处于不同职业阶段（研究生到教授）的美国研究人员以及类似的中国同行参加。 山区正在经历冰冻圈的快速转变，失去了永久的冰雪，而这些冰雪可以缓冲排放，塑造区域环境和栖息地条件，并为人类提供多样化的生态系统服务。冰冻圈正在发生的变化是广泛而复杂的，影响着高山湖泊和溪流的各种关键参数，如温度、透明度、流量和养分供应。记录、理解和预测这些影响具有挑战性，需要广泛的跨学科合作。继 2017 年 8 月在中国青海湖举办的第一届研讨会取得成功之后，即将在美国举办的第二届研讨会有两个目标： 1. 评估生物群的基本相似性（例如新陈代谢的温度依赖性或生物量的化学计量特征）可以帮助了解冰冻圈损失对水生生态系统的影响；2. 建立中美联合数据中心框架，在两国多个地点建立数据库。本次研讨会将通过美国和中国研究人员的合作来促进国际合作，这些研究人员致力于解决两个地区共同的、紧迫的环境问题，建立概念框架并为数据共享和合作创造先例。合作研讨会的高度跨学科性质也将为包括研究生和博士后在内的所有职业阶段的参与者提供重要的专业发展机会和培训。有关研讨会的更多信息，请访问 https://renzedyk.wixsite.com/us-china-workshop2 该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
