Our primary research goal is to produce transformative, synergistic research through an inclusive collaborative culture that crosses disciplinary and institutional boundaries and is embedded throughout the Center’s activities. C-DEBI was established with a focus on three deep subseafloor biosphere projects (“Major Programs”), helping to coordinate activities associated with these projects in collaboration with U.S. and international partners. Each of these projects seeks to complete an integrated, scientific mission to resolve the nature, diversity, extent, and activity of the subseafloor biosphere in the deep sea. C-DEBI research projects address questions applied to two distinct subseafloor biosphere environments, igneous ocean crust and overlying sediments, that have historically been studied independently. C-DEBI is led by co-PIs from five U.S. universities, but seeks to build and leverage scientific, educational, and technological partnerships with numerous U.S. and international institutions (educational, research, outreach, engineering, not-for-profit). In addition, C-DEBI seeks to develop a community of multidisciplinary collaborators, to identify promising topics, and to develop new projects that will help to advance the Center's objectives.
Target 1: The initial three Major Programs are managed, and momentum is developed in new areas, to transform understanding of subsurface life.

Target 2: The research theme areas are developed in order to grow and cross fertilize between Major Programs and facilitate the development of new projects that would not have been realized without the mechanism of the STC.
Metric

Status/Problems
|
Develop 3 new themes based on past workshop reports and results to encourage synthesis and integration across themes and sites
Fluxes, Connectivity, and Energy: centering on subseafloor environmental conditions
Activities, Communities, and Ecosystems: emphasizing resident microbial communities
Metabolism, Survival, and Adaptation: concentrating on the actions and traits of individual activity in the deep subseafloor biosphere

4. Plans for the Next Reporting Period
The research plans for the next reporting period remain as initially stated. Considerable progress has been made with the three initial Major Programs (which include ongoing experiments and monitoring), and the new Major Program Dorado Outcrop has been launched. The STC is also focused on synthesis and integration across themes and sites. In 2015, we are holding two “synthesis and integrations” workshops for basements and sediments. Beyond examining scientific results across a variety of sites, we will also focus on “lessons learned” from different types of sample collection, experiments, and other important points related to this.
