Sample text

The role of these electrolytic forces at these depths is not yet understood, but it does appear that a smooth transition from bacteria that dominate primarily at the oxidation–reduction interface and the bacteria below occurs. At these greater depths, the bacteria become aggressively reductive, fundamentally stripping various nutrients (phosphorus, nitrogen, and sulfur) from the descending organics and leaving various hydrocarbon (CxHy) compounds, primarily in the form of methane and petroleum.

Not only is water essential to life on Earth but of its two elements, oxygen dominates the oxidative zone and hydrogen dominates the reductive zone. The oxygen and hydrogen dominances meet at the oxidation–reduction interface, generating a constant and measurable electrical output measured in millivolts that are positive in the oxidative environment and negative in the reductive. It could be conjectured that the oxidation–reduction interface commonly located in water provides a natural focal point for electrolysis.

There is an old adage that “what goes down then comes up” and this applies to the completion of the organic carbon cycle within planet Earth. Reduced forms of carbon as gases and hydrocarbons may now move upward through the crust as volatiles, gases, or seepages of the lighter density fractions of oils. Another interfacial layer of biomass forms and follows one of two alternative functions: (1) volatile and gaseous hydrocarbons along with seepage are broken down at the oxidation–reduction interface to generate biomass; or (2) gaseous hydrocarbons (specifically methane) are accumulated at the oxidation–reduction front along with ice to form energy-rich gas hydrates (clathrates).
