This data relates to the calculation of bio-energetics for South Pacific Gyre marine sediment (site U1370).
BCO-DMO Processing Notes:
– added conventional header with dataset name, PI name, version date
– modified parameter names to conform with BCO-DMO naming conventions
Estimated age of an organism or a sample. Units and methods vary by dataset (e.g. years, months, days); values are numeric.
wet weight of a specific taxa/group identified; refer to dataset for units of measurement.

Microorganisms buried in marine sediments endure prolonged energy-limitation over geological timescales. This C-DEBI project will investigate energy and activity levels among microbial communities in the marine subsurface. We use thermodynamic and microbial-biogeochemical modelling principles to explore and quantify:
– The energy sources to deeply buried microorganisms and their demand for energy.
– The activity of microorganisms and the factors that determine physiological transitions between active and dormant states.
– The varying energy requirements of active and dormant microbes and the allocation of energy between maintenance and growth.
– The cell-specific energy utilization (i.e. power) of subsurface life on a global scale.
