  1. Current Status of USArray and EarthScope Thanks to Bob Woodward USArray Director

  2. EarthScope Components • Plate Boundary Observatory (PBO) • GPS measurements at ~900 stations in western US • Strain meter installations • 71 borehole strainmeters • 5 laser strainmeters • 75 borehole seismic stations • San Andreas Fault Observatory at Depth (SAFOD) • Instrumented borehole • Core Samples • High Sample Rate Seismic Recordings • US Seismic Array (USArray) • Transportable Array • Flexible Array • Reference Network • Magnetotelluric Network

  3. Data Management EarthScope Portal • Portal is launched All Time series data are available at the IRIS DMC from all EarthScope Components In FDSN SEED format

  4. Transportable Array • As of December 9, 2008 • 693 commissioned • 449 operating • 244 removed November 2007 November 2008

  5. Canada Collaboration • POLARIS-USArray collaboration:

  6. Flexible Array Equipment: • 326 broadband • 120 short period • 1700 active source

  7. Reference Network > 100 stations in contiguous US USGS ANSS, Regional Networks, USArray Permanent Array, TA

  8. Magnetotellurics Transportable Array Backbone • 170 campaign sites (2006, 2007, 2008) • Backbone is complete • 7 backbone sites MBB06 Miles City, MT

  9. DMC Data Holdings • The DMC manages • 84 terabytes of waveform data • 14 terabytes of EarthScope data • 9 terabytes of USArray data

  10. Gigabytes Shipped by Category

  11. Composite USArray Performance

  12. DMC USArray Products • ANF Phase Picks (4/13/04 - 8/31/08) • SPADE by month • ISF, XML, Report View • SeismiQuery • ISF, CSV, XML

  13. DMC Products: Tomographic Models • Approach: • Convert existing models to the common format • Simple text format • Luca Postpischi compact format • netCDF format • Currently Supported Models: • NA04 - VanDerLee, S3D - Romanowicz, A1D - Romanowicz, • CUB - Shapiro, and SEND2 – Lees • REM 2/4 degree (UNAVCO) • Next Step • Compilation of GMT scripts to slice models • Browser based front-end to drive GEON-IDV to produce slices through the models • Coordination with FDSN • FDSN Working Group III • Tuesday 13 January 2009 at 5PM
