A facilities program for collection and distribution of seismological data for research and education related to: Earthquakes Earth Structure Earth Dynamics David Simpson, IRIS CIDER Marconi Conference Center May 19, 2009

Facilitate and conduct geophysical investigation of seismic sources and Earth properties using seismic and other geophysical methods. Promote exchange of geophysical data and knowledge, both through use of standards for network operations, data formats and exchange protocols, and through pursuing policies of free and unrestricted data access. Foster cooperation among IRIS Members, Affiliates, and other organizations in order to advance geophysical research and convey benefits from geophysical progress to all of humanity. IRIS Mission

IRIS - Consortium and Facilities (with possible connections to CIDER) Let science lead Close links between science and facilities No in-house research CIDER as intellectual driver Engage and renew community involvement Respond to community leadership and advice Renew through E&O Links to CIDER education and training Build facilities that facilitate Carefully spec’ed, designed and tested instrumentation Data management that works for research community “24 bits wide - 70 terabytes deep” Links to COMPRES and other geophysical and geological databases Emphasis on quality and service Extension into services and products Links to CIDER, CIG Develop multi-use, multi-agency, multi-national support Links to CIDER interdisciplinary science

NSF Support for Seismology and Deep Earth Evidence for Optimism Invitation for Response IRIS and GSN 25 years of sustained support for development and operation Recent 2009 ARRA - Stimulus actions NSF and USGS combined support of $10M for GSN revitalization EarthScope O&M support through 10/10 Cascade Initiative - “on-shore - off-shore” Significant increases in R&RA science support - FY’09 & beyond Science Planning NSF request for Long Range Science Plan for Seismology IRIS - refreshed GSN Science Plan - early 2010 EarthScope - ESSC Science Plan - January 2010 IRIS Proposal submission - fall 2010 Dynamic Earth Initiative at GEO level Led by Bob Detrick 2010 and beyond

Long Range Science Plan for Seismology Background From the IRIS- NSF Cooperative Agreement: “The IRIS Consortium will consult broadly with the research community to develop a new long-range science plan for global seismology that will guide potential future improvements and enhancements to the IRIS facilities.”

Seismological Grand Challenges Prepared by the Seismological Grand Challenges Writing Group Thorne Lay, Editor Richard C. Aster, workshop tri-chair Donald W. Forsyth, workshop tri-chair Barbara Romanowicz, workshop tri-chair Richard M. Allen Vernon F. Cormier Joan Gomberg John A. Hole Guy Masters Derek Schutt Anne Sheehan Jeroen Tromp Michael E. Wysession The long-range plan is based on a workshop held in September 2008 and attended by ~120 members of the seismological and geophysical community.

Seismological Grand Challenges in Understanding Earth’s Dynamic Systems Ten Grand Challenges for Seismology 1.How do faults slip? 2.How does the near-surface environment affect natural hazards and resources? 3.What is the relationship between stress and strain in the lithosphere? 4.How do processes in the ocean and atmosphere interact with the solid Earth? 5.Where are water and hydrocarbons hidden beneath the surface? 6.How do magmas ascend and erupt? 7.What is the lithosphere-asthenosphere boundary? 8.How do plate boundary systems evolve? 9.How do temperature and composition variations control mantle and core convection? 10.How are Earth’s internal boundaries affected by dynamics?

Seismological Grand Challenges in Understanding Earth’s Dynamic Systems Sustaining a Healthy Future for Seismology –Building and sustaining the professional pipeline –Enhancing access to high-performance computing capabilities –Sustaining global observatories –Advancing portable instrumentation –Providing controlled seismic source support –Producing advanced seismological data products –Enhancing free and open access to data –Enhancing interdisciplinary coordination
