Scientific Data in the Digital Age“It is exceedingly rare that fundamentally new approaches to research and education arise. Information technology has ushered in such a fundamental change. Digital data collections are at the heart of this change.”
US National Science Board, Report to the US National Science Foundation,, 2005

Access to Data
“Effective access to research data, in a responsible and efficient manner, is required to take advantage of the new opportunities and benefits offered by new information and communication technologies.”
Organization for Economic Co-operation & Development:
“Principles and Guidelines for Access to Research Data from
Public Funding”
May 2007

Open Access to Data: Benefits Democratize access to research resources
Ensure broad dissemination of results Facilitate new cross-disciplinary approaches - access for non-
specialist users Enable verification of research results Provide new research opportunities
Provide access to data from variety of sources and enable integration across fields
Provide foundation for use of automated tools Facilitate more efficient use of resources
Data are often expensive to collect (especially marine!) often/usually unique, repeat collection/analysis rare

Sharing Research Data: USA
“GAO recommends the agencies explore opportunities in the grants process to better ensure the availability of data to other researchers and determine if additional archiving strategies are warranted.”

Improving Global Data Access
Agreed on statements of principle and recommendations to address technical, procedural, and organizational issues of open global data sharing.
“Building a Global Data Network for Studies of Earth Processes at the World’s Plate Boundaries”International Workshop, Kiel (Germany), May 2007. Attended by 71 people from 14 countries.Sponsored by the MARGINS, Ridge2000, InterMARGINS, InterRIDGE programs.

Workshop Recommendations Science User Needs
Access to all data needed to reproduce scientific results Access to multidisciplinary & integrated marine & terrestrial data
Data Documentation & Publication Uniform best practices & standards for data acquisition, data
submission to data centers & data publication Easy procedures for metadata creation & data submission
Data & Metadata Interoperability Minimize proliferation of metadata standards Development of a data discovery service across distributed data
resources Opportunities & Obstacles for International Data
Sharing Leverage international bodies & programs (e.g. GEOSS, eGY, ICSU,
IPY) Establish dedicated task group & special interest groups to advance
implementation of a global data network
