About
Kevin Manganini is a biogeochemist whose research focuses on the cycling of greenhouse gases in Arctic coastal systems, with a particular emphasis on methane (CH₄) dynamics. His most impactful work, the 2020 paper “River Inflow Dominates Methane Emissions in an Arctic Coastal System” (57 citations), provides a critical year-round time series of dissolved CH₄ and CO₂ in a river and estuary near Cambridge Bay, Nunavut. This study revealed that river inflow during the spring freshet is the dominant driver of methane emissions in ice-covered Arctic estuaries—a process previously under-observed due to a strong summer bias in Arctic field campaigns. By capturing the brief but intense ice-melt period, Manganini demonstrated that conventional measurements significantly underestimate the region’s greenhouse gas flux. His 2019 companion paper (4 citations) extended this work to include nitrous oxide (N₂O), further highlighting the seasonal complexity of Arctic biogeochemistry. Manganini’s contributions are vital for refining climate models, as they fill a major observational gap in high-latitude carbon cycling. His work underscores the outsized role of freshwater inflow in shaping Arctic coastal greenhouse gas budgets, making him a key voice in understanding how a rapidly warming Arctic alters global methane emissions.
