Margaret S. LeinenAssistant Director for Geosciences

Incorporated Research Institutionsfor Seismology(IRIS)Action Item NSB/CPP-2006-13Award RecommendationMay 10, 2006


  • Governance and management of the IRIS facilities

  • Snapshots of IRIS facility programs

  • Management and proposal review

  • Implications for NSF oversight

  • Recommendation

Science enabled by the gsn deep earth structure
- Science Enabled by the GSN -Deep Earth Structure

Three-dimensional Earth tomography from seismic wave speeds

Anomalous hot - buoyant (orange) & cold - dense (blue) regions

Structure of mantle heterogeneity, subduction zones &

core-mantle boundary zone (earth dynamics)

Science enabled by passcal imaging lithospheric structure
- Science Enabled by PASSCAL -Imaging Lithospheric Structure

Supporting researchon high-resolution structure of the lithosphere

Cross-section from the southern Rocky Mountains reveals “fossil” subduction structures remnant from ancient continental construction

An example of dms data mining glacial earthquakes
- An Example of DMS “Data Mining” -Glacial Earthquakes

A previously unknown class of low frequency “earthquakes” revealed through exploration of the GSN data archive (noise)

Produced by sudden glacial sliding - strong seasonality & increasing frequency may be indicative of glacial response to climate change

Proposal Review Analysis

  • 11 of 15 reviewers judged proposal excellent

  • Ambitious proposal with significant expansion of the IRIS facilities

  • Review revealed that some of these enhancements were justified while others need further study prior to reconsideration

  • Important for IRIS & NSF to consider carefully the timing of these new activities & the potential to leverage resources

Implications for NSF Oversight

  • The next cooperative agreement will stipulate the following activities to aid NSF in its management of the IRIS facilities:

  • IRIS will consult broadly with the research community to develop a new long-range plan that will guide potential future improvements & enhancements to the IRIS facilities.

  • IRIS will conduct a review of the PASSCAL Program.

  • IRIS will implement an external evaluation of the E&O Program; follow-up review by NSF.

  • NSF will conduct an interim management review. We will inform the NSB of the results of this management review.

  • NSF staff will work with IRIS & other Federal agencies to address the critical issue of STS-1 sensor replacement (GSN refresh).


RESOLVED, that the National Science Board authorizes the Director, at his discretion, to make an award to the Incorporated Research Institutions for Seismology (IRIS) for renewed support of the seismology facilities and programs operated by IRIS for an amount not to exceed $86,000,000 for a period of 60 months. - May 10, 2006

Strategic Planning Exercise

Complement 2001 NRC-BROES report as well as 2006 NRC study of “Grand Research Questions in the Solid-Earth Sciences”.

Led by a community working group (6-10) endorsed by NSF.

CHARGE: “To guide the science community in the development of a long-term vision & a recommended strategy for global seismology at NSF” (EAR, OCE, OPP communities).

TASK: Identify broad scientific challenges in seismology (5-10 years) with strategic priorities staged assuming limited resources.

OUTCOME: Final report that will aid the process of setting priorities for improvements & enhancements to the IRIS facilities.

Seek advice from the community, from within NSF, & from other organizations; brief your scientific colleagues (AGU); maintain reports at open web site to invite comments from community.

Separate proposal to EAR/IF from WG chair – final report by December 2007.
