Coastal survey GPS data, historic sea ice extent, nearshore wave data, historical flood history, tidal datums, and infrastructure risk for western Alaska including Goodnews Bay and St. Paul Island 2020-2025

As part of NSF Project 1848542, we assessed the impacts of Bering Sea storms on western Alaskan communities, focusing on Goodnews Bay and St. Paul Island. Field campaigns collected high-resolution coastal datasets to document storm-driven flooding and shoreline change. Cross-shore profiles were surveyed using a Trimble real-time kinematic global navigation satellite system (RTK-GNSS), extending from upland features to the waterline and repeated over time to capture coastal change. High-water marks (HWMs) were also recorded, providing elevation data for present and historic flooding events, including detailed measurements of Typhoon Merbok impacts in 2022. Indicators such as debris lines, seed lines, foam lines, and wet/dry lines were used to approximate total water levels, which integrate astronomical tide, storm surge, and wave runup. This dataset contains supporting tables and measurements from these surveys, which complement a broader assessment of storm flooding impacts on regional infrastructure. We encourage researchers to contact us with questions or requests for additional data.

作为美国国家科学基金会（National Science Foundation, NSF）项目1848542的一部分，本研究评估了白令海风暴对阿拉斯加西部社区的影响，研究重点关注古德纽斯湾（Goodnews Bay）与圣保罗岛（St. Paul Island）。野外科考活动采集了高分辨率海岸数据集，用于记录风暴引发的洪涝灾害与海岸线变化情况。研究团队采用天宝（Trimble）实时动态全球导航卫星系统（real-time kinematic global navigation satellite system, RTK-GNSS）开展跨岸剖面测量，剖面范围从高地地貌延伸至水岸线，并进行多次重复观测以捕捉海岸动态变化。研究同时记录了高水位标记（high-water marks, HWMs），可为当前及历史洪涝事件提供高程数据，其中包含2022年梅尔博克台风（Typhoon Merbok）影响的详细测量结果。研究人员以碎屑带、种子带、泡沫带及干湿边界等标识为依据，估算得到整合天文潮汐、风暴潮与波浪爬高效应的总水位值。本数据集包含上述科考活动产生的配套表格与测量数据，可作为区域基础设施风暴洪涝影响全面评估的补充支撑材料。我们欢迎研究人员就相关问题或额外数据需求与我们取得联系。
