Abstract

A methane concentration alteration experiment was performed to test the influence of methane concentration on methane oxidation rate. Together with the oxygen concentration alteration experiment, the purpose of this experiment was to test the assumption that methane oxidation in the Santa Barbara Basin deep water column follows first order kinetics.

Methodology: 

Sampling and analytical procedures: 

Methane concentrations were measured by headspace equilibration method, modified from Kinnaman et al., 2007.

Fractional methane turnover rates were analyzed based on the 3H-labeled methane incubation protocol by Bussmann et al., 2015.

Methane oxidation rates were calculated assuming adherence to the first-order rate law, by multiplying fractional methane turnover rate and ambient methane concentration (Valentine et al., 2001).


Samples were collected from R/V Connell.

Dataset: Initial Oxygen Concentration Alteration Data
Relationship Description: Initial methane concentration alteration experiment, together with initial oxygen alteration experiment and time course experiment, serve as supports for the assumptions of the methane oxidation rate measurement method. Initial methane and oxygen alteration experiments also help to identify the relevance of methane and oxygen as direct controls on the kinetics of methane oxidation rates.
