WALIS stands for “World Atlas of Last Interglacial Shorelines”. It is a database collecting data on Last Interglacial (70-125 ka) sea-level proxies. Each data point in WALIS follows a standard template that can be filled from an online interface. WALIS is part of the WARMCOASTS project, funded by the European Research Council, and falls under the purview of the PALSEA working group (supported by PAGES and INQUA).
The data in WALIS is organized in a Zenodo Community. A series of manuscripts in a Special Issue of the journal Earth System Science Data describes each region included in the database. The latest version of the global database is also included in the GitHub repository linked at this page and archived in Zenodo.
WALIS data can be queried and visualized via a ShinyApp interface. The R code used to develop the app is available in Github and Zenodo. In addition, we developed other query and plotting tools in a series of Jupyter notebooks, available at the GitHub repository linked on the side of this page and archived in Zenodo.
Anyone can create an account and work with our interface to insert data on sea-level proxies and associated dated samples. Our interface is (and will remain) free, only requiring registration. If you already have the data standardized in WALIS format and want to submit them to Zenodo, the link below resolves directly to the data submission page for our community.
We know that, for less experienced users, the large number of fields in WALIS might appear intimidating. For this reason, we prepared a ReadTheDocs page and a series of YouTube tutorials to facilitate data insertion and help the user to understand the database structure better. Both are a continuous work in progress, so don’t hesitate to get in touch with email@example.com for questions, bug reports, and requests. The ReadTheDocs files are also hosted in GitHub, and the latest docs version is stored in Zenodo.
We are constantly working to improve WALIS and the associated tools. One of the most extensive developments is extending the database and the interface to include Holocene sea-level datapoints. For this, we are working with the HOLSEA community, and we have been recently financed by PAGES via two Data Stewardship Scholarships.
WALIS is the result of the work of several people. For this reason, we kindly ask you to follow these simple rules to acknowledge those who worked on it correctly.
Example. The data used in this study were extracted from / compiled in WALIS, a sea-level database interface developed by the ERC Starting Grant “WARMCOASTS” (ERC-StG-802414), in collaboration with PALSEA (PAGES / INQUA) working group. The database structure was designed by A. Rovere, D. Ryan, T. Lorscheid, A. Dutton, P. Chutcharavan, D. Brill, N. Jankowski, D. Mueller, M. Bartz, E. Gowan and K. Cohen. The data points used in this study were contributed to WALIS by list names of database contributors here.
This software is part of a project that has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (Grant agreement No. ERC-StG-802414)
