Rocky coastlines around the world often show signs of storm or tsunami inundation in the form of long-lived coastal boulder deposits. However, their interpretation remains controversial. It is still not possible to infer the magnitude of inundation with any accuracy, or in some cases even to determine whether the deposits were generated by storm waves or by tsunamis. The Inundation Signatures on Rocky Coastlines (ISROC) Research Coordination Network will bring together researchers from the United States and other countries around the world to define the field as a whole, establish standards, bring together existing and new data into a central database, and define priority research topics. Collaborations may be both virtual and in-person, all dependent on safety protocols. Student training will be a priority during this 5 year project, with the HBCU University of the Virgin Islands serving as the home site for the Year 3 Student Conference and Workshop, and a second Workshop in Year 5 at a different site. Short-term research exchanges and student visits will take place throughout the project. Coastal boulder deposits (CBD) are signatures of extreme marine inundation found on many rocky shorelines worldwide. However, their interpretation remains contentious, with debate extending to whether clasts were deposited by storm waves or tsunamis, and the immediate implications for risk and planning. Reconstruction of the hydrodynamic conditions and climatology leading to CBD generation has even greater uncertainty. Nevertheless, these long-lived deposits provide what are sometimes the only records of historic and prehistoric inundation, so reconstructions have direct application to understanding past and present conditions, and high predictive value for future inundation regimes. Here, the Inundation Signatures on Rocky Coastlines (ISROC) Research Coordination Network is proposed to (1) Define the overall CBD problem chain and associated research gaps by developing a network of researchers from different disciplines, locations, and backgrounds; (2) Extend and train the community of researchers, in particular to include groups underrepresented in STEM at locations where CBDs are found; (3) Develop CBD disciplinary standards for gathering and archiving data; (4) Develop and implement cyberinfrastructure for researchers to upload, visualize, and analyze CBD data; and (5) Create opportunities for cross-disciplinary, in-person, and online collaboration and exchange.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.

世界各地的岩石海岸线经常以长期存在的海岸巨石沉积的形式显示出风暴或海啸淹没的迹象。然而，他们的解释仍然存在争议。人们仍然无法准确地推断出洪水的大小，在某些情况下甚至无法确定这些沉积物是由风暴波还是海啸产生的。洛基海岸线淹没特征研究协调网络（ISROC）将汇集来自美国和世界其他国家的研究人员，将该领域定义为一个整体，建立标准，将现有和新数据汇集到一个中央数据库中，并确定优先研究主题。合作可以是虚拟的，也可以是面对面的，都依赖于安全协议。在这个为期5年的项目中，学生培训将是一个优先事项，维尔京群岛的HBCU大学将作为三年级学生会议和研讨会的主会场，五年级的第二个研讨会将在不同的地点举行。短期研究交流和学生访问将贯穿整个项目。海岸巨石沉积（CBD）是全球许多岩石海岸线上极端海洋淹没的标志。然而，他们的解释仍然存在争议，争论延伸到碎屑是由风暴波还是海啸沉积的，以及对风险和规划的直接影响。导致CBD产生的水动力条件和气候学的重建具有更大的不确定性。然而，这些长期存在的沉积物有时提供了历史和史前淹没的唯一记录，因此重建可以直接应用于了解过去和现在的情况，并对未来的淹没制度具有很高的预测价值。在此，建议建立岩质海岸线淹没特征（ISROC）研究协调网络：(1)通过建立一个由不同学科、地点和背景的研究人员组成的网络，界定CBD的整体问题链和相关研究缺口；(2)扩展和培训研究人员群体，特别是在发现cbd的地区纳入STEM中代表性不足的群体；(3)制定CBD数据采集和归档的学科标准；(4)开发和实施网络基础设施，供研究人员上传、可视化和分析CBD数据；(5)创造跨学科、面对面和在线协作与交流的机会。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
