Over the past six decades, the scientific ocean drilling (SOD) programs have collected vast and invaluable data for Earth history research. However, the scattered state of these data across multiple repositories, along with inconsistent standards, methodologies, and terminologies, have increased the complexity of data processing and posed barriers to its effective utilization. While several databases have been developed to consolidate and improve access to SOD data, each has limitations in scope. To address these challenges, we introduce the Sediment Spatial and Temporal Database (SedST, http://sedst.org), a new platform designed to aggregate chronological data from the extensive archives of SOD, including postcruise literature, and provide tools for data accessibility. SedST standardizes biostratigraphic, magnetostratigraphic, and radiometric dating records, aligning them with the latest Geologic Time Scale 2020, to ensure consistency and coherence. Employing the Bchron methodology, SedST establishes age-depth models for >1000 SOD boreholes. Presently, SedST encompasses 37,329 entries from 181 expeditions and 1300 holes, covering the world's ocean basins and including records as old as the Late Jurassic. The platform provides powerful tools for sample ID to depth conversions and individual hole to composite site depth transformation. Accessible via user-friendly graphical interfaces, SedST simplifies data queries and allows the export of search results in CSV format. As a constantly developing platform under the umbrella of the Deep-time Digital Earth program, SedST is committed to enhancing the accessibility and discoverability of marine sediment data, fostering new insights into Earth's geological history.
