摘要：tephra is a unique volcanic product with an unparalleled role in understanding past eruptions, long- term behavior of volcanoes, and the efects of volcanism on climate and the environment . Tephra deposits also provide spatially widespread, high-resolution time-stratigraphic markers across a range of sedimentary settings and thus are used in numerous disciplines (e.g., volcanology, climate science, archaeology). Nonetheless, the study of tephra deposits is challenged by a lack of standardization that inhibits data integration across geographic regions and disciplines. We present comprehensive recommendations for tephra data gathering and reporting that were developed by the tephra science community to guide future investigators and to ensure that sufcient data are gathered for interoperability. Recommendations include standardized feld and laboratory data collection, reporting and correlation guidance. these are organized as tabulated lists of key metadata with their defnition and purpose . They are system independent and usable for template, tool, and database development. this standardized framework promotes consistent documentation and archiving, fosters interdisciplinary communication, and improves efectiveness of data sharing among diverse communities of researchers.
