Concern: Reproducibility11
“The field sciences (e.g., geology, ecology, and archaeology), where each study is temporally (and often spatially) unique, provide exemplars for the importance of
preserving data and samples for further analysis.”

Data: Publishers’ PerspectiveMany have had supplements for some time.
Difficult to deal with, costlyPDF’s mostly (not searchable, poorly indexed, variable quality)
Require authors to comply with data availability policy; policing
Little guidance on community standards
Want to use and promote repositories, but not well integrated except for a few exceptions
Worried about repository funding and stability

Statement of CommitmentCOPDESS.orgreaffirm and ensure adherence to our existing journal and
publishing policies…regarding data sharing and archiving...
Signed by ~50 publishers & data facilities
“Earth and space science data should, to the greatest extent possible, be stored in appropriate domain repositories that ... follow leading practices, and can provide additional data services.”

Science question:Do convergent margin volcanoes really represent continental crust?
“As it is crucial to understand the extent and origin of the compositional difference between central Aleutian lavas and plutons through time and space, this project will map and sample plutonic rocks exposed on the central Aleutians and their coeval volcanic host rocks.”

“Observations commonly involve sampling of an ultimate feature of interest. This International Standard defines a common set of sampling feature types classified primarily by topological dimension, as well as
samples for ex-situ observations.” (OGC O&M 2.0.0 / ISO19156; editor: Simon Cox)
