FIGURE 1.3 Graphical representation of DSDP, ODP, and IODP holes drilled between 1974 and 2005 that extend more than 200 m into ocean crust. The most striking observation on this diagram is that most of the holes are shallower than 500 m and sample only the volcanic section (pillows and sheeted dikes) of the basement below the sedimentary cover.

system and their importance in developing new fields of inquiry, and identification of goals not yet accomplished. The report also examined capacity building, education, and outreach conducted through DSDP, ODP, and IODP (Chapter 5).

For the second task, the committee relied upon presentations by the science plan writing team, discussions with representatives from IODP and NSF, and review of the plan itself. The committee was presented with several versions of Illuminating Earth’s Past, Present, and Future: The International Ocean Discovery Program Science Plan for 2013-2023 (IODP-MI, 2011) during the course of the study. The draft plan was released in June 2010; the committee met with science plan writing team members during the September 2010 meeting. The committee also received some revised chapters in September and October 2010, which were significantly different in both content and style from the June 2010 version. Revisions continued throughout the rest of 2010, and the revised document was reviewed by an external panel of eight international scientists in early 2011 (IODP-MI, 2011). The final science plan was released in June 2011 and provides the basis for the committee’s assessment of future opportunities for transformative science through scientific ocean drilling (Chapter 6). The committee also identified linkages between scientific ocean drilling, other NSF-supported programs, and non-NSF programs.
