这项研究的一个关键组成部分是绘制南极海床地形和冰厚参数图，这些参数对于冰流模型的建立以及预测未来冰损失和随之而来的海平面上升至关重要。在南极研究科学委员会的支持下，Bedmap 3行动小组的目标不仅是为国际科学界制作新的冰厚和海床地形网格图，而且还将制作Bedmap网格产品所使用的所有地球物理调查数据点标准化并提供这些数据点。在这里，我们记录了最新迭代Bedmap3中使用的调查数据，合并并添加到以前用于Bedmap1和Bedmap2的所有数据集，包括自20世纪50年代以来所有南极地球物理活动的冰床，表面和厚度点数据。更具体地说，我们描述了用于标准化和使这些和未来的调查和网格化数据集可访问的过程，根据可查找，可扩展，可互操作和可重用（FAIR）的数据原则。为了使网格化过程具有可重复性，并允许科学家自由地重新使用数据进行自己的分析，我们引入了新的SCAR Bedmap数据门户网站（bedmap.scar.org，最后访问时间：2023年3月1日），旨在通过网络地图界面提供对这些重要数据集的前所未有的开放访问。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保存数据的生命周期。数据可从英国极地数据中心获取：https://data.bas.ac.uk（最后访问时间：2023年5月5日）。有关数据集的完整列表，请参见数据可用性部分。
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 the 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 surveys and gridded datasets accessible under the Findable, Accessible, Interoperable, and Reusable (FAIR) data principles. With the goals of making the gridding process reproducible and allowing scientists to re-use the data freely for their own analysis, we introduce the new SCAR Bedmap Data Portal (https://bedmap.scar.org, last access: 1 March 2023) created to provide unprecedented open access to these important datasets through a web-map 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 (last access: 5 May 2023 ). See the Data availability section for the complete list of datasets.
