Abstract. Over the past 60 years, scientists have strived to understand the past, present and future of the Antarctic Ice Sheet. One of the key components of this research has been the mapping of Antarctic bed topography and ice thickness parameters that are crucial for modelling ice flow and hence for predicting future ice loss and ensuing sea level rise. Supported by the Scientific Committee on Antarctic Research (SCAR), the Bedmap3 Action Group aims not only to produce new gridded maps of ice thickness and bed topography for the international scientific community, but also to standardize and make available all the geophysical survey data points used in producing the Bedmap gridded products. Here, we document the survey data used in the latest iteration, Bedmap3, incorporating and adding to all of the datasets previously used for Bedmap1 and Bedmap2, including ice-bed, surface and thickness point data from all Antarctic geophysical campaigns since the 1950s. More specifically, we describe the processes used to standardize and make these and future survey and gridded datasets accessible under the ‘Findable, Accessible, Interoperable and Reusable’ (FAIR) data principles. With the goals to make the gridding process reproducible and to allow scientists to re-use the data freely for their own analysis, we introduce the new SCAR Bedmap Data Portal (bedmap.scar.org, last access: 18 October 2022) created to provide unprecedented open access to these important datasets, through a user-friendly webmap interface. We believe that this data release will be a valuable asset to Antarctic research and will greatly extend the life cycle of the data held within it. Data are available from the UK Polar Data Centre: https://data.bas.ac.uk.

南极床图数据：FAIR 共享 60 年的冰床、表面和厚度数据

摘要。在过去的 60 年里，科学家们努力了解南极冰原的过去、现在和未来。这项研究的关键组成部分之一是绘制南极床地形和冰厚度参数的地图，这些参数对于模拟冰流至关重要，因此对于预测未来的冰损失和随后的海平面上升至关重要。在南极研究科学委员会 (SCAR) 的支持下，Bedmap3 行动小组的目标不仅是为国际科学界制作新的冰层厚度和床层地形网格图，而且还旨在标准化和提供所有使用的地球物理调查数据点在生产 Bedmap 网格化产品时。在这里，我们记录了最新迭代 Bedmap3 中使用的调查数据，合并并添加到之前用于 Bedmap1 和 Bedmap2 的所有数据集，包括自 1950 年代以来所有南极地球物理活动的冰床、地表和厚度点数据。更具体地说，我们描述了根据“可查找、可访问、可互操作和可重用”(FAIR) 数据原则使这些和未来的调查和网格化数据集标准化和可访问的过程。为了使网格化过程可重现并允许科学家自由地重复使用数据进行他们自己的分析，我们推出了新的 SCAR Bedmap 数据门户（bedmap.scar.org，最后访问时间：2022 年 10 月 18 日），旨在提供通过用户友好的网络地图界面，前所未有地开放访问这些重要数据集。我们相信，此次数据发布将成为南极研究的宝贵资产，并将大大延长其中所含数据的生命周期。
