Biological oxygen production from oxygen-to-argon ratios and oxygen isotopologues in the Atlantic Ocean
… measure net community production (N) and gross oxygen production (G) in two different areas relevant for the marine C cycle: the South Atlantic subtropical gyre and the North Atlantic during a spring bloom. The former despite small rates of production it is relevant for the global marine C cycle …

Oxygen-oxygen bonds : catalytic redox pathways in energy storage
… intimately tied to the chemical bond between two oxygen atoms. The common theme that ties my research projects in the Nocera group in the past four years is an interest in systems that transfer energy through the making and breaking of oxygen-oxygen bonds. 0-0 bonds are some of the weakest …

Sediment Oxygen Demand Kinetics
Hypolimnetic oxygen diffusers increase sediment oxygen demand (SOD) and, if not accounted for in design, can further exacerbate anoxic conditions. A study using extracted sediment cores, that included both field and laboratory experiments, was performed to investigate SOD kinetics in Carvin's Cove …
