REPORT ORGANIZATION

The committee evaluated the five assessments contracted by DOE (tides, waves, ocean currents, marine thermal gradients/OTEC, and rivers and in-stream). Each of the assessments is presented in a separate chapter, which introduces the basic resource, describes the project, comments on assessment methodology and validation, and offers conclusions and recommendations. The discussion of tides can be found in Chapter 2, waves in Chapter 3, ocean currents in Chapter 4, OTEC in Chapter 5, and riverine and in-stream flows in Chapter 6. A discussion of the practical MHK resource and constraints posed by socioeconomic and environmental filters is included in Chapter 7, and overarching conclusions and recommendations are presented in Chapter 8.

Evaluations of the resource assessments are based on presentations by the assessment groups and DOE to the committee at each of its six meetings (meetings and presentations to the committee are detailed in Appendix D). The committee also received written responses to its questions from each of the groups. Chapters 2 and 3 are based on information initially discussed in the committee’s interim report (NRC, 2011). These chapters have been updated to include information that had not been available at the time of the interim report release. For this report, the committee reviewed final assessment reports for the waves, tides, and OTEC assessment groups and a July 2012 draft final report from the riverine assessment group.6 No final report was available for review from the ocean currents resource assessment group; its report is expected to be complete by June 2013. Instead, the committee based its evaluation on presentations from and discussions with the assessment group.
