8. Status Mostly: Salary for IS management team – Note: some are fractionally supported from other awards (USArray, Polar, GLISN, etc.) Small amounts for travel, M&S, Pubs & Printing Revised downwards from previous projections – Mostly due to lower than expected salary for Fowler – Delayed hiring (all planned hiring now complete) Note that this will change substantially for FY14-18 due to inclusion of full salaries

9. Instrumentation Services: FY14-18 IRIS CoCom Meeting Chicago April 9-10, 2012

10. WBS 3.1 – IS Management Same structure as at present – Salaries, travel, M&S, Pubs and printing Salaries will include 100% of IS managers – Some fine tuning of this required

11. WBS 3.1.7 - Magnetotellurics Scoped a slightly more ambitious plan than asked Should achieve three significant “footprints” Proposed structure and activities are essentially the same as today – But – may need to trade some field work against buying replacement equipment – No sensors replaced in nine years (running the same 20 instruments the whole time) 11

12. WBS 3.1.7 – Magnetotellurics – New Initiatives Presented two concepts for new initiatives at last BoD meeting – Full-48 Expanding the MT TA to cover the full 70 x 70 km grid in the lower 48 Cost: ~ double the base MT budget (additional ~$600-700K / year) – Prototype Alaska transect A road-based transect of up to MTsite in Alaska Setting stage for post-2018 MT activities Cost: ~$150-170K / year BoD meeting takeaways – These new initiatives are non-starters 12
