Rocky coasts make up over half of the world’s coastlines. Each day, these coastlines are hammered by the force of thousands of crashing waves, causing the coastline to retreat, sometimes catastrophically. As climate changes and ocean waves become more extreme, potential acceleration of coastal retreat poses significant threats to natural habitats, cultural heritage, coastal communities, and critical infrastructure. However, the influence of extreme waves on rocky coast erosion is not well-known, limiting the prediction of evolving coastal hazards. This project will synthesize environmental, topographic, and geologic datasets, use innovative seismic monitoring techniques, and develop new models to understand the sensitivity of rocky coast erosion and coastal hazards to extreme waves. The project will integrate research activities into public-facing outreach and university education, including newly developed educational modules and online interactive tools, both leveraging publicly accessible, live-streamed datasets. This project aims to understand how variable wave action translates to coastal erosion and sea cliff retreat on rocky coastlines. The work is structured around three components: (1) quantifying how tectonics and near-shore morphology control wave energy delivery to rocky shores, (2) measuring near-shore wave transformation and sea cliff response across a range of settings, and (3) piloting a coastal erosion model that accounts for wave climate, wave filtering effects, and cliff erosion thresholds. The project's main contributions include a probabilistic description of wave energy delivery, direct field measurement of wave climate translation to coastal geomorphic work, and a novel erosion model quantifying coastal sensitivity to shifting environmental extremes.This 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.

岩石海岸占世界海岸线的一半以上。每天，这些海岸线都会被数千次撞波的力量锤击，导致海岸线撤退，有时是灾难性的。随着气候变化和海浪变得越来越极端，沿海撤退的潜在加速对自然栖息地，文化遗产，沿海社区和关键基础设施具有重大威胁。但是，极端海浪对岩石海岸侵蚀的影响并不是众所周知，这限制了不断发展的沿海危害的预测。该项目将综合环境，地形和地质数据集，使用创新的地震监测技术，并开发新的模型，以了解岩石沿岸侵蚀和沿海危害极端波的敏感性。该项目将将研究活动整合到面向公共的外展和大学教育中，包括新开发的教育模块和在线互动工具，既利用了公开访问，实时流程的数据集。该项目旨在了解可变的波动动作如何转化为岩石海岸线上的沿海悬崖和海悬崖撤退。这项工作围绕三个组成部分进行结构：（1）量化构造和近岸形态控制波能量向岩石海岸传递，（2）测量一系列环境中近岸波转换和海悬崖响应的测量，（3）驾驶沿海侵蚀模型，这些模型是波动气候，波气候，波浪气候，波浪气候效应，和含量效果，以及含量，以及含量，和含量。该项目的主要贡献包括对波动能量传递的概率描述，波动气候转化为沿海地质形态工作的直接现场测量以及一种新颖的侵蚀模型，量化了沿海对环境极端变化的敏感性。这奖反映了NSF的法定任务，并通过使用基础的智力效果评估来评估，以评估良好的支持。
