The World Atlas of Last Interglacial Shorelines (Version 1.0)

Abstract

Abstract. In this manuscript, we present Version 1.0 of the World Atlas of Last Interglacial Shorelines (WALIS), a global database of sea-level proxies and samples dated to Marine Isotope Stage 5 (~80 to 130 ka). The database includes a series of datasets compiled in the framework of a Special Issue published in this journal (https://essd.copernicus.org/articles/special_issue1055.html). This manuscript collates the individual contributions (archived in Zenodo, https://zenodo.org/communities/walis_database/) into an open-access, standalone database (Rovere et al., 2022, https://doi.org/10.5281/zenodo.6623428). The release of WALIS 1.0 includes complete documentation and scripts to download, analyze, and visualize the data (https://alerovere.github.io/WALIS/). The database contains 4545 sea-level proxies, 4110 dated samples and 280 other time constraints, interconnected with several tables containing accessory data and metadata. By creating a centralized database of sea level proxy data for the Last Interglacial, the WALIS database will be a valuable resource to the wider paleoclimate community to facilitate data-model integration and intercomparisons, assessments of sea level reconstructions between different studies and different regions, as well as comparisons between past sea level history and other paleoclimate proxy data.
