  1. IC GS Introduction to the geological specification Harvey Thorleifson, Association of American State Geologists Harvey Thorleifson, 13 March 2007

  2. Geological maps • an essential service

  3. CLIMATE CHANGE • we require geological mapping to fulfill our objectives NGDC

  4. Climate change: the need for geological mapping • geology explains earth system linkages, climate processes, & carbon sources/sinks • geology guides work on natural records that document variability, drivers, extreme events, & regional impacts • geology will guide carbon capture and storage by deep geologic sequestration • geology identifies thresholds & vulnerabilities in coastal zone dynamics, sea level change, permafrost degradation, reduced glacier cover, groundwater quality and quantity, flooding, dust storms and landslides

  5. geological mapping plays an essential role in addressing the full range of human needs • Heritage • Health • Security • Wealth

  6. Role of geological mapping • Heritage • Earth • Oceans • Land • Life

  7. Role of geological mapping • Health • Toxic substances • Waste disposal

  8. Role of geological mapping • Security • Hazards

  9. Role of geological mapping • Wealth • Materials • Energy • Engineering

  10. Role of geological mapping • Water • Heritage • Aquatic ecosystem integrity

  11. Role of geological mapping • Water • Health • groundwater protection • source water composition

  12. Role of geological mapping • Water • Security • Flooding • Shoreline erosion

  13. Role of geological mapping • Water • Wealth • water resources

  14. Role of geological mapping • Heritage • Health • Security • Wealth • an essential service

  19. Benefits to our agencies • Increased awareness of our role • Increased awareness of our products • Increased use of our products • Increased support for our role • Increased benefits for our users

  20. 1G goal • Coordinated web accessibility of existing ~1:1M mapping, in its current geologic format Our task • produce the 1st version of the 1G geological specification & establish a process to revise it

  21. Question: • What sort of geological specification will OneGeology require?

  22. OneGeology geological specification • National scale, commonly 1:500k - 1:5M • Your principal geological map, whether bedrock, surficial, or combined • Ownership & control remains with you; credit to your agency is clear • You have already written the geological specification for your map • Is that enough?

  23. Considerations • Topographic base • Language • Time scale • Lithology • Structure • Genesis • Cover – offshore, lakes, ice, sediments

  24. Discussion required • Throughout the meeting • This afternoon • Wednesday morning breakout • Thursday morning presentation • Post-meeting discussions

  25. Geological maps • an essential service
