Presentation given at the EGU 2015 General Assembly in session "Methods for Understanding Volcanic Hazards and Risks" (NH2.2), describing EarthChem data systems that make accessible and synthesize geochemical data of volcanic rocks and gases, and the System for Earth Sample Registration that catalogs sample metadata and provides persistent unique sample identifiers (International Geo Sample Number IGSN). It also mentions EarthChem's plans and ongoing work to link geochemical data with other volcanological databases, and the IEDA data rescue initiative.

Coalition for Publishing Data in the Earth &
Space Sciences (COPDESS)
13
Joint initiative of Earth Science publishers and Data Facilities to help
translate the aspirations of open, available, and useful data from
policy into practice.
Reaffirm and ensure adherence to existing journal and publishing policies and
society position statements regarding open data sharing and archiving of data,
tools, and models.
Ensure that Earth science data will, to the greatest extent possible, be stored in
community approved repositories that can provide additional data services.
Statement of Commitment signed by all major Earth & Space Science
publishers.
Build an online community directory of appropriate Earth science
community repositories for data, tools, and models that meet
leading standards on curation, quality, and access

IEDA Data Rescue
Mini-awards (<$7,000) to compile data at risk
Example: “Geochemistry of volcanic gases from Kamchatka”
Tobias Fischer (DCO DECADE; University of New Mexico, USA), with
expert Russian gas geochemist Yuri Taran (Universidad Autonoma de
Mexico), Elena Kalacheva (IVS, Kamchatka) and Nicole Thomas (UNM)
20 datasets extracted from old Russian literature and formally published
in the EarthChem Library
