Margaret S. LeinenAssistant Director for Geosciences
Incorporated Research Institutionsfor Seismology(IRIS)Action Item NSB/CPP-2006-13Award RecommendationMay 10, 2006
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)
Supporting researchon high-resolution structure of the lithosphere
Cross-section from the southern Rocky Mountains reveals “fossil” subduction structures remnant from ancient continental construction
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
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
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.
