Abstract:

Direct measurements of methane concentrations, microbially mediated aerobic methane-oxidation rates (for example, methanotrophy) and particulate methane monooxygenase gene abundance were made in the water column. Concentrations of inorganic nutrients were also quantified to explore the factors potentially regulating methanotrophic activity.

Purpose:

To report spatially extensive measurements of methane concentration and oxidation rates in the nine months following the Macondo blowout and to shed light on the response dynamics of methanotroph.
