Focused CoPe: Building Community Sensor Networks for Coastal Hazards and Climate Change Impacts in Southeast Alaska

该奖项的全部或部分资金来自《2021年美国救援计划法案》(公法117-2)。阿拉斯加东南部的高降雨率和陡峭的地形结合在一起，造成洪水和山体滑坡，危及生命和财产。这个重点关注的COPE中心将把地球科学家、大气科学家和当地居民聚集在一起，在整个地区部署和监测自然灾害传感器网络。该中心将在项目仪表盘中整合天气预报和实时传感器数据。在线仪表盘将使阿拉斯加六个部落社区的成员能够规划和准备应对极端降雨灾害及其对生计活动的影响。作为一个创新的、社区主导的项目，这个中心寻求回应与当地相关的研究问题，同时增加农村和阿拉斯加原住民学生和社区成员的参与度和体验式学习的机会，这些学生在STEM学科中的代表性不足。作为该枢纽基础的传感器网络包括倾倒斗式雨量计、流量计以及通过卫星遥测连接到区域仪表盘的土壤湿度和地下水传感器。该仪表板将结合机器学习和对实时传感器数据的贝叶斯分析，以创建一个滑坡预警系统，该系统可能会被修改，以用于其他容易发生灾害的美国社区。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2).The high precipitation rates and steep topography of Southeast Alaska combine to create flooding and landslides that endanger lives and destroy property. This Focused CoPe hub will bring geoscientists, atmospheric scientists, and local residents together to deploy and monitor a network of natural hazard sensors across the region. The hub will integrate weather forecasts with real-time sensor data in a project dashboard. The on-line dashboard will enable members of six Alaska tribal communities to plan and prepare for extreme rainfall hazards and the subsequent impacts on subsistence activities. An innovative, community-led project, this hub seeks to respond to research questions of local relevance while increasing engagement and opportunities for experiential learning among rural and Alaska Native students and community members, who are underrepresented in STEM disciplines. The sensor networks that are the foundation of this hub include tipping-bucket rain gauges, stream gauges, and soil moisture and groundwater sensors connected to the regional dashboard via satellite telemetry. The dashboard will incorporate machine learning and Bayesian analysis of real-time sensor data to create a landslide warning system that may be modified for use in other hazard-prone U.S. communitiesThis award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
