New Science Plan Considerations from New Science Plan Considerations from IWG+ to the SPWCIWG+ to the SPWC

30-40 pages, including implementation plan

Aimed at broad scientific community to excite many

Mix of exciting basic science and societally relevant science

Should fit with strategic and national priorities of members

Assume 8-12 months JR; 5 months Chikyu, 1 MSP per year

Identify specific high priority riser projects for Chikyu

Include borehole experiments

Highlight linkages to other large programs

Incorporate education and outreach throughout the Plan

Grand Challenges for the New Drilling Program

• Climate Change: Records from the Past; Lessons for the Future

• Deep Life: Exploration of the Marine Intraterrestrials

• Renewing the Lithosphere: Consequences for our Planet

• Earth in Motion on Human Timescales: Plate Boundaries, Fluid Flow and Active Experimentation

Proposed Activities to Foster Community Support

Step 1: Develop a 3-person support team to assist in this effort (in

negotiation)

• Develop 1-pagers on major accomplishments for each theme/discipline

• Develop presentation content on Science Plan for new drilling program

• Presentations:

- universities (can USAC DLS speakers assist?)

- professional societies of other fields

• Workshop for post-docs and early career scientists

• Visits to NSF for briefings

• Visits to Congressional staff for briefings

• Encourage scientists to talk to Presidents, Deans, etc.

• Section on renewal in re-launched IODP Newsletter
