Interactive effects of salinity, redox, and colloids on greenhouse gas production and carbon mobility in coastal wetland soils
Abstract
Coastal wetlands, including freshwater systems near large lakes, rapidly bury carbon, but less is known about how they transport carbon either to marine and lake environments or to the atmosphere as greenhouse gases (GHGs) such as carbon dioxide and methane. This study examines how GHG production and organic matter (OM) mobility in coastal wetland soils vary with the availability of oxygen and other terminal electron acceptors. We also evaluated how OM and redox-sensitive species varied across different size fractions: particulates (0.45–1µm), fine colloids (0.1–0.45µm), and nano particulates plus truly soluble (Published: January 3, 2025
