3. FY13-14 New Initiatives PIF-GSN-2012-01 – Infrasound - $90K – Procurement and integration effort to incorporate ~4 – 4 element infrasound arrays into GSN station. – Prep for 5 year larger deployment PIF PIF-GSN-2011-09 – OBS Installation - $250K – Coordinate with OBS community to improve non-ROV emplacement techniques to improve horizontal performance – Pan-IRIS – coordinate with OMO PIF-GSN-2011-11 – Array workshop - $95K – Facilitate a workshop on science and design associated with broadband arrays. – In preparation for pan-IRIS proposal initiative

5. GSN 5 year budget (2013-2018) Target level is reduced to $2.4M – No more to cut but personnel. What are the implications for target? Equipment rich, people poor Slow deployments and responsiveness Reduction in Quality Inflation (salary/fringe) further cuts with time Loss of personnel – experience that is not easy to get back SC requests base equivalent to FY13 base – Still requires FTE reduction, but sustainable. – Mandatory California inflation still a factor

6. GSN-Programmatic Initiatives 1.Site Refurbishment (PIF-GSN-2012-09) – WBS 3.1.4.3.2.1 – Quality improvements at GSN stations – $150K per year for all GSN 2.Strategic Densification/relocation (PIF-GSN-2012-02) - WBS 3.1.4.3.2.2 – Years 3-5 to allow use of quality initiative 3.Infrasound (PIF-GSN-2012-10) – WBS 3.1.4.4.2 – Expansion of FY13 developments to GSN – $300K/year for 5 years - ~50 stations 4.Met Packages (PIF-GSN-2012-11) – WBS 3.1.4.4.3 – Enhancement to Infrasound and adds to Geophysical Observations at GSN 5.Next Gen Primary Sensors (PIF-GSN-2012-07)– WBS 3.1.4.3.1 – Continued procurements

7. Pan-IRIS Initiatives 1.Next Gen DAS (PIF-GSN-2012-06) – WBS 3.1.4.3.1 – Preparation for end of life of current GSN DAS – $200K in FY18 – Coordinate with PASSCAL and TA next gen DAS evaluation 2.Broadband Array Deployment (PIF-GSN-2012-03) - WBS 3.1.4.5 – 5 year plan for procurement, installation and operation – $7.2M total estimate – relies on array workshop for final costs – Possible implementation by PIC or some new facility 3.Subduction Zone Observatory (PIF-GSN-2012-04) – WBS 3.1.4.7 – 5 year plan for procurement, installation and operation – $2.16M total estimate – ties to Cascadia possible – Possible implementation by PIC or some new facility – tied to UNAVCO for GPS component 4.OBS BB experiment add-on (PIF-GSN-2012-05) – WBS 3.1.4.8 – Data mining and workshop to add-on to OBS experiment with long-term BB station, utilizing non-ROV enhanced emplacement (FY13 PIF). – Procure and test waveglider technology for low level telemetry – Ties to OMO

9. BACKGROUND – AS NECESSARY

10. External Sources of Funding Although the IRIS level of funding for the GSN has shown a sharp decline in recent years, we have been working for many years on seeking support from outside core IRIS funds for the recapitalization of the equipment for the network. Funding from external sources has been as follows: 2009 – NSF augmentation (facilitated by the American Recovery and Reinvestment Act (ARRA)) - ~$5M – These funds were for upgrading the GSN to the next generation field systems and secondary sensors. – We are spending down the last ~$500K of these funds this Spring 2009 – USGS ARRA funds - ~$5M – These funds are the USGS contribution to the GSN upgrade 2010 – Dept of Energy - $250K – Procurement of Secondary Sensors 2011 – Dept of State - $402K –Spare systems and site infrastructure to improve performance of the GSN station participating in the IMS (IRIS/IDA stations) 2011 – Dept of State - $215K - Spare systems and site infrastructure to improve performance of the GSN station participating in the IMS (IRIS/USGS stations) 2012 – Department of Energy - $5.7M – Procurement of Primary Sensors
