ESA Coastal Erosion Space for Shore CCN #3

The ESA Coastal Erosion project has been a productive and collaborative effort, yielding significant results and strengthening the partnership between i-Sea and NORCE. Over the course of the project, we produced an impressive set of 676 products in Norway, including 470 results this year alone. These outputs represent a valuable contribution to the understanding of coastal dynamics in Arctic regions, particularly through the innovative use of radar imagery for monitoring changes over different time scales. One notable achievement is the effectiveness of our method for measuring atmospheric exposure in the intertidal zone, which has proven particularly valuable for assessing glacier fronts. This approach provides a new metric for understanding glacier calving dynamics and underscores the potential of combining remote sensing techniques with targeted geophysical analyses. However, the project was not without its limitations. Time constraints prevented us from fully exploring some of the more ambitious research objectives initially outlined. Furthermore, while we have successfully produced a robust base of products, a deeper analysis of the observed changes remains necessary. This next phase of work will require close collaboration with end-users to ensure the relevance and applicability of the findings to real-world challenges. Looking ahead, the groundwork laid by this project offers a strong foundation for future research and operational applications. Continued efforts to refine and interpret the datasets will provide valuable insights into coastal processes, glacier dynamics, and the impacts of climate change on Arctic environments. By building on the achievements of this project, we aim to further enhance the scientific understanding and practical management of these critical and rapidly changing regions.
