Influence of carbon source and iron oxide minerals on methane production and magnetic mineral formation in salt marsh sediments
Abstract. Salt marshes can emit significant methane to the atmosphere. These emissions are highly variable, but the cause of this variability is not well understood. Although methanogenesis should be…

Zinc stimulation of phytoplankton in a low-carbon-dioxide, coastal Antarctic environment: evidence for the Zn hypothesis
Abstract. The ocean acts as a carbon sink, absorbing carbon from the atmosphere and resulting in substantial uptake of anthropogenic CO2 emissions. As biological processes in the oceans such as net…
