Nature and Extent of the Deep Biosphere

Creator:

Colwell, Frederick S. and D’Hondt, Steven

Abstract:

In the last three decades we have learned a great deal about microbes in subsurface environments. Once, these habitats were rarely examined, perhaps because so much of the life that we are concerned with exists at the surface and seems to pace its metabolic and evolutionary rhythms with the overt...

Bacterial dominance in subseafloor sediments characterized by methane hydrates

Creator:

Briggs, Brandon R., Inagaki, Fumio, Morono, Yuki, Futagami, Taiki, Huguet, Carme, Rosell-Mele, Antoni, Lorenson, Thomas D., and Colwell, Frederick S.

Abstract:

The degradation of organic carbon in subseafloor sediments on continental margins contributes to the largest reservoir of methane on Earth. Sediments in the Andaman Sea are composed of ~ 1% marine-derived organic carbon and biogenic methane is present. Our objective was to determine microbial abundance and diversity in sediments that...
