Data Science in Cosmochemistry: Using all data for original research with an example from chondrule-matrix complementarity

Dominik Hezel
GU Frankfurt

The past years have seen various and significant efforts to make cosmochemical data FAIR (Findable, Accessible, Interoperable, Reproducible). The MetBase database has been founded almost 30 years ago, but we only recently could transformed it to a paywall-free database. Last year, the NFDI4Earth (nfdi4earth.de) consortium started as part of the national research data infrastructure (nfdi.de), an almost 1 billion Euro initiative. At the GU Frankfurt, we are Co-Spokesperson of the NFDI4Earth. The NFDI4Earth seeks to build an infrastructure to connect Earth System Science (ESS) databases and repositories, accessible via a single OneStop4All. Cosmochemical databases are regarded as part of ESS, and access to cosmochemical databases will be integrated into the NFDI4Earth. In a pilot project within the NFDI4Earth, we currently align the database schema of MetBase with NASA’s Astromaterials database, and build a Web-Interface for quick data-access, -visualisation, -modelling, and -download. The starting point will be the existing, comprehensive MetBase web-interface. Together with our colleagues from Astromaterials, we are also in the process to merge MetBase and Astromaterials into one single database. Desperately required standards and metadata for cosmochemical data are planned to be provided – although not necessarily developed – by the just started, global OneGeochemistry initiative, which is part of the EU funded WorldFAIR project. The OneGeochemistry initiative includes cosmochemistry and is led by e.g., our colleagues from Astromaterials, as well as us. I will present a short overview of these efforts and initiatives. More importantly, I will use two examples to illustrate the potential of cosmochemical data science. In these, I will show that chondrules as well as chondrules and matrix were not formed independently at different locations in the protoplanetary disk and later mixed together, but rather locally from the same reservoir.
