  1. Introduction to the International Continental Scientific Drilling Program Uli Harms, ICDP, GFZ Potsdam, Germany ulrich@gfz-potsdam.de

  2. ICDP is an international funding program providing: Financial and logistical drilling support for inter-national Earthscience teams with a need for drilling

  3. Themes of the ICDP

  4. Positive International Review 20 projects, 40 workshops, ~ 1000 scientists involved

  5. ICDP: Organization and Function

  6. ICDP Membership Member Countries • Germany • USA • Japan • China • Canada • Austria • Norway • Mexico • Poland • Czech Republic • Iceland • Finland • South Africa • Member Organizations • UNESCO • Schlumberger • Negotiations • Russia • Italy • Spain • New Zealand • Sweden • Interests • Korea • Chile • Israel • Netherlands • Great Britain • France • Argentina • Ireland

  7. Global Criterion Problem of Global Significance “World-Class” Geological Site International Criterion Broad International Collaboration Best Possible Science Team Pooling of Resources and Technology Societal-Needs Criterion Relevance of Problem to Society Collaboration with Industry Need-for-Drilling Criterion Proof of Necessity for Drilling Depth-to-Cost Criterion Balancing of Costs and Drilling Design Criteria for Selection of ICDP Projects

  8. Project Development Procedure

  9. Funding Strategy ICDP funds are granted for project development and drilling-related expenses, but not for science support • Foster International Co-operation and Project development through Workshops (seed money to lift projects) • Form partnerships with other scientific, private, governmental or industry groups for project funding • Direct money to drilling operations, scientific-technical on-site support, facilities and data management • Fund science proposals on sites of global significance

  10. ICDP Workshops Goals • Formulate focussed ScientificObjectives • Define specific Operational Targets • Form an active and convincing Scientific Team and Project Structure • Draft Plans incl. Funding-, Budget-, Operations-, Management- Plan • Write and Submit a Full Drilling Proposal to ICDP and other agencies

  11. ICDP Workshops Fault Zone Drilling, Japan Mar ´06 Lake Van, Turkey, Apr. ´06 HOTSPOT, USA, May ´06 Chicxulub, Germany, Sep. ´06 Mutnovsky Volc., Russia, Sep. ´06 Campi Flegrei, Italy, Nov. ´06 COREF Coral Reef, Japan, Jan. ´07 Anatolian Fault, Turkey, Apr. ´07 Nankai on-land Drill, Japan, Aug ´07 Mjölnir Crater, Norway, Sep. ´07

  12. Prerequisites for Success • A bright scientific idea to study processes or/and test important hypothesis that are only accessible through drilling • Drilling at Sites of Global Scientific Importance and Societal Relevance as Examples for Comparable Settings • Excellent geophysical and geological Site Surveys to justify drilling target, drilling depth, and to reduce drilling risks • Technical Feasibility and Budget Realities • Environmental and Societal Compliance.

  13. Organizational Prerequisites • Successfull application to ICDP plus other agencies to collect Commingled Funding / Cooperation with Industry • Scientific Leadership coupled with Team Capabilities of Lead PIs • Home Institutes and NationalSupport andAcknowledgement • Formation of a Workable Scientific Team • Communication and Planning Skills in PI Group and in the Scientific Team - Constant information, reminders, commendations • Experience with Drilling Projects and Large / International Projects • Engineering Support and good Relation to Drilling Contractors • Sufficient Contingency Funding / Risk Margin

  14. Operational Support Through ICDP Operational Support Group • Main OSG Personell Functions: • Provide technical and managerial assistance to PI´s • Support for scientific and engineering drill site operations • Support for field facility for sample description, scanning and handling • Provide a readily accessible ICDP data management system • Training and Courses for all of the above

  15. Operational Support (cont.) Main OSG Equipment and IT Support: • Drilling equipment and engineering. • Downhole logging tools, instruments, cables, winches. • Drill site science and tools, mobile field lab, core logging, core scanning, on-line fluid analysis (mud gas logging). • Information and data management system, Drilling Information System, WWW

  41. SAG Review Guidelines (Guide to Presenters) • Overview of project/workshop goals and strategy (What are they proposing to do and why?). • Proposal history (previous submissions as pre or full proposals. Is proposal result of ICDP-funded workshop?). • Quality of science to be addressed (fundamental issues of global significance; also considering need for drilling and societal relevance). • Qualifications of proponents (experience and productivity of PIs, breadth and international diversity of science team/workshop attendees, sound project management plan). • Adequacy of site characterization (Is drilling target already well defined? Are permitting and environmental approvals in hand?). • Technical feasibility (Are we confident project will succeed? Is operational plan logical and well thought through? Is prior experience of PIs or input from OSG well utilized?). • Cost effectiveness (Is the budget carefully prepared? Is there an efficient drilling/testing/sampling plan? Does it take advantage of existing holes, cost sharing or linkages to industry?). • Summary recommendation by SAG (approve, approve with caveats, modify and resubmit, reject).
