MARHYS Database 1.0

MARHYS (MARine HYdrothermal Solutions) database is a global compilation of marine hydrothermal vent fluid compositions. The database includes data presented in journal publications, book chapter and monographs and includes compositions of hydrothermal fluids, end members and background seawater. Detailed sample information (metadata) is provided along with the chemical composition and enables unique identification of discrete vent fluid samples. The database contains concentrations of major-, minor- and trace elements, as well as, reduced carbon compounds and isotope compositions. All concentrations are converted into units per kg of vent fluid and chemical data of unique samples reported in different publications are merged to unique sample entries.
