Deep Life
We are exploring the frontier of the "deep biosphere" - microbial life in the rocks and sediments that makes up 70% of our planet's surface.

Novel Organisms
This previously unknown bacillus living 342 meters below the ocean floor is one of very few isolated from the subseafloor crust.

Studying these organisms will reveal important, novel, and basic insights into the unique metabolic features of microbes in the deep biosphere.

It's Slow Growing: Novel Approaches
Visualization methods like "BONCAT" reveal important, novel, and basic insights into the unique metabolic features of microbes in the deep biosphere, as in the slow-growing, archaeal-bacterial consortium anaerobically oxidizing methane in deep sea sediments pictured here.

Global Implications
About 0.6% of Earth's total living biomass is in subseafloor sediments. This finding updates previous estimates made in 1998.

Science & Technology
We require specialized technologies to collect and analyze samples from the deep biosphere, including sensors, samplers, and platforms, deep-sea submersibles, scientific drilling research ships, and ROVs (remotely operated vehicles).

Training & Outreach
Get involved with our education, outreach and diversity opportunities for teachers, K-12, undergraduates, graduate students, and postdoctorals in our quest to train and foster the next generation of deep biosphere researchers.

Science communication semifinalists, next Virtual Meeting and Networked Speaker
Posted: March 15, 2021

Message from the Director:

Congratulations to the Reach Out Science Communication Challenge semi-finalists from C-DEBI: Sabrina Elkassas (MIT-WHOI) and Rachel Weisend (Texas A&M Corpus Christi)! Cheer them on as they compete among 18 others in the Reach Out Semifinals live tentatively on April 13 (4PM Pacific) to the panel of expert science communicator judges: Raven Baxter, Emily Calendrelli, Jorge Cham, and Melissa Cristina Márquez. More details to come.

We are also pleased to announce the inaugural event for our C-DEBI Virtual Meeting Series based on your enthusiasm for C-DEBI community activities at our last annual meeting. Ben Tully (USC) and Jake Weissman (USC) will kick off the series on new tools in bioinformatics on Monday April 5 (10:30AM – 12:00PM Pacific). Save the date for this first of our virtual events to be held monthly during the first week of each month, with a regular rotation of science workshops and professional development workshops. Each workshop will contain about 90 minutes of programming, including invited speakers to give plenary tutorials and presentations, breakout sessions, and plenary Q&A sessions. Stay tuned for more information.

Don’t forget to also tune in to our final C-DEBI Networked Speaker Series talk “Outwit, Outplay, Outlast: A microbial tale of survival within the marine deep subsurface” presented by Megan Mullis (Texas A&M University at Corpus Christi) on March 18 at 12:30PM Pacific Time.
