Relative sea level (RSL) predictions based on glacial isostatic adjustment (GIA) simulations and palaeotidal predictions generated by hydrodynamic models using GIA‐generated palaeotopographies are available in the published literature, and datasets are available via data repositories. However, these data are often difficult to extract for specific locations or timeslices, requiring users to request datasets from corresponding authors. To overcome the intractability of these data and to enable users to interrogate datasets themselves without requiring offline requests, we have developed PALTIDE, an online visualization tool with intuitive user interface accessible at https://shiny.bangor.ac.uk/paleotidal/. The model domain for this interactive visualization tool is the northwest European continental shelf, covering the period from the Last Glacial Maximum (LGM) to the present day, and is based on previous GIA simulations by Bradley and colleagues and hydrodynamic simulations using Regional Ocean Modelling System (ROMS) published by Ward and colleagues. The tool is developed in R and utilizes a number of packages including shiny and bslib for the frontend, and arrow, raster and the tidyverse for backend data processing. The tool enables visualizations and data downloads for RSL, tidal amplitude and tide‐dependent parameters for any location within the model domain over 1000‐year timesteps from the LGM to the present.

交互式可视化和数据门户工具 (PALTIDE)，用于自末次盛冰期以来欧洲西北部陆架海的相对海平面和古潮汐模拟

基于冰川均衡调整 (GIA) 模拟的相对海平面 (RSL) 预测和使用 GIA 生成的古地貌通过水动力模型生成的古潮汐预测可在已发表的文献中找到，并且可通过数据存储库获取数据集。然而，这些数据通常很难提取特定位置或时间片的数据，需要用户向相应作者请求数据集。为了克服这些数据的棘手性，并使用户能够在不需要离线请求的情况下自行查询数据集，我们开发了 PALTIDE，这是一种在线可视化工具，具有直观的用户界面，可在https://shiny.bangor.ac.uk/paleotidal/。该交互式可视化工具的模型域是欧洲西北部大陆架，涵盖从末次盛冰期 (LGM) 至今的时期，并且基于 Bradley 及其同事之前的 GIA 模拟以及使用区域海洋建模系统进行的水动力模拟（ROMS）由 Ward 及其同事出版。该工具是用 R 开发的，并利用了许多软件包，包括闪亮的和BS库对于前端，以及箭,光栅和整洁宇宙用于后端数据处理。该工具可以对从末次盛宴到现在 1000 年时间步长的模型域内任何位置的 RSL、潮汐幅度和潮汐相关参数进行可视化和数据下载。
