Methods to improve data discoverability have become increasingly important as new datasets proliferate in the Earth sciences. One of the cornerstones of data discoverability is metadata, especially metadata that is of high quality (correct, complete, consistent), as high-quality metadata is most effective when leveraged in data discovery interfaces and tools. The goal of this session is to explore innovative efforts to improve Earth science data discoverability. This could include metadata stewardship tools or processes, controlled vocabularies and ontologies, or collaborative/crowd-sourced metadata creation and maintenance. The path to data discovery can have many different sources whether it be a specialized data discovery portal or broader search engines like Google’s Dataset Search. Stewardship and management practices that help connect users to data are welcomed. Aspects of these practices that help improve data accessibility and usability will also be explored. This session continues the discussion started at last year’s 2020 AGU fall meeting.
