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.

Message from the Director:

We hope this fall semester treats you safe and well. We also congratulate these C-DEBIers who have recently been promoted or are starting new positions: Brandon Briggs (Associate Professor at University of Alaska Anchorage); Joy Buongiorno (Assistant Professor at Maryville College); Jackie Goordial (Assistant Professor at the University of Guelph); Jeff Marlow (Assistant Professor at Boston University); Bill Orsi (Associate Professor at LMU Munich); Brandi Reese (Associate Professor at Dauphin Island Sea Lab); Haley Sapers (Assistant Professor at York University); Lauren Seyler (Assistant Professor at Stockton University); Jason Sylvan (Associate Professor at Texas A&M University); and Katrina Twing (Assistant Professor at Weber State University).

And stay tuned for our next season of Networked Speaker Series talks! Dr. Rose Jones (University of Minnesota) kicks it off with “Menu for a deep microbe: Attempts in understanding microbe-mineral interactions in the deep marine seafloor” on September 10 at 12:30PM Pacific Time. Our other distinguished speakers include Dr. Julia McGonigle (Bigelow), Dr. Jesse Colangelo-Lillis (CU Boulder), and Megan Mullis (Texas A&M Corpus Christi).

Cheers,

Jan Amend
C-DEBI Director
