  4. Summary • Broadband seismogram database http://www.jamstec.go.jp/pacific21/ • Network Data Center system by using web services http://www.jamstec.go.jp/pacific21/ • Earth science data viewer using Google Earth http://www.jamstec.go.jp/pacific21/ • XML SEED for broadband seismograms http://www.jamstec.go.jp/pacific21/xmlninja • XML SEED for synthetic seismograms http://www.jamstec.go.jp/pacific21/ninja_synth

  5. Earth Science data onGoogle Earth • Multi purpose geoscience data viewer • Integration of geochemical and geophysical data. • Efficient use of various format data. • Tool to convert geoscience data to a KML file • We adopted Google Earth.

  6. Target data • Navigation data of JAMSTEC vessels. • Geochemical rock data. • Tomography model data.

  7. KAIREI 2003

  8. Zoom up KAIREI 03-08

  9. Information of KAIREI 03-08

  10. Information of KAIREI 03-08 (2)

  11. Landscape of sea floor

  12. Navigation data on Google Earth • Multiple routes. • Detail path. • Information ( contain link to Database ). • Date. • Temperature and sea depth.

  13. Geochemical rock data • PetDB and GEOROC. • Excel file from PetDB. • CSV file from GEOROC.

  14. SiO2 at Pacific Ocean from PetDB Red ~ Blue

  15. Main compositions blue:SiO2, dark blue: TiO2, light green: Al2O3, purple: Cr2O3, green: Fe2O3, dark green: FeO yellow green: MnO, orange: MgO, emerald: CaO, gray blue: Na2O, light blue: K2O, violet: P2O5 black: residual

  16. Geochemical rock data on Google Earth • Color, Height, Thickness of bar graph. • Various composition data. • Shape of bar graph. • Ratio between compositions. • Main compositions. • PetDB + GEOROC.

  17. Tomography model • Text data. • Data file at each depth.

  18. Global tomography model Obayashi et al., 2006

  19. Global tomography model (model information) Obayashi et al., 2006

  20. Vertical cross section Obayashi et al., 2006

  21. Tomography model on Google Earth • Global / Local model. • Information of the model. • A part of original model. • Vertical cross section along any profile. • http://www.jamstec.go.jp/pacific21/

  22. Development of conversion tool • Original data to a KML file. • Navigation data, geochemical rock data and tomography model. • Easy and quick data plotting. • Various data on Google Earth together.
