C-DEBI (Center for Dark Energy Biosphere Investigations) is a National Science Foundation (NSF) Science and Technology Center on the deep subseafloor biosphere. Our mission is to explore life beneath the seafloor and make transformative discoveries that advance science, benefit society, and inspire people of all ages and origins. We are a multi-institutional distributed center establishing the intellectual, educational, technological, cyber-infrastructural and collaborative framework needed for transformative experimental and exploratory research on the subseafloor biosphere. C-DEBI is led by Drs. Jan Amend (C-DEBI Director, University of Southern California), Julie Huber (Marine Biological Laboratory), Steven D’Hondt (University of Rhode Island), Andrew Fisher (University of California, Santa Cruz), and C. Geoffrey Wheat (University of Alaska, Fairbanks). Connect with us via our mailing list on Facebook and on our twitter!

Application for Teacher Small Grants to open January 5, 2014!
Deadline: February 16, 2015

The K-12 Teacher Small Grants program supports K-12 teachers who have attended a C-DEBI teacher-training program and have incorporated C-DEBI content into their classrooms. These awards up to $2500 support items including but not limited to the following: funds for student field trips, classroom supplies, travel for presenting C-DEBI curriculum at educator meetings, or additional professional development directly related to C-DEBI research. Proposals for funding should indicate how C-DEBI research content is being translated into the classroom and how the proposed activities connect to that content. [Read More]

 Now receiving applications for the Global Environmental Microbiology (GEM) Summer Course!
Deadline: February 3, 2015

The GEM Course is an all-expenses paid, four-week intensive introductory course in Global Environmental Microbiology (GEM) geared for early career undergraduates from 2 and 4 year colleges/universities that focuses on microbes found in aquatic environments investigated through authentic research experiences (students collect, process & interpret data). This residential course includes lectures, labs and fieldwork at USC, the Eastern Sierra Mountains, and on Santa Catalina Island. [Read More]

 Special Call for Deep Biosphere Research Proposals
Deadline: January 15, 2015

The NSF Science and Technology Center for Dark Energy Biosphere Investigations (C-DEBI) invites proposals for one-year projects that will significantly advance our central research agenda—to investigate the subseafloor biosphere deep in sediments and the crust. C-DEBI intends to fund 2-3 proposals in response to this call, up to $100,000 each. C-DEBI has a deep appreciation of the specific challenges that accompany microbiological investigations and the study of biogeochemical processes in the deep subsurface, and encourages research that addresses these challenges through approaches such as timely analyses of perishable samples, experiments with live samples, refining or adapting difficult techniques, or applying well-established methods to the analysis of substantial sample sets. C-DEBI also encourages basic research on biogeochemical processes that will lead to better understanding of subsurface microbial activities, and marine hydrogeological studies performed in the context of C-DEBI research themes.
