About

Dr. Brent Else is a leading Arctic biogeochemist whose research centers on greenhouse gas dynamics in polar coastal systems, with a particular focus on methane and carbon dioxide fluxes. His most impactful work, "River Inflow Dominates Methane Emissions in an Arctic Coastal System" (2020, 57 citations), provides a rare year-round time series of dissolved methane in a river and estuary near Cambridge Bay, Nunavut, revealing that river inflow during the spring freshet is the primary driver of methane emissions in ice-covered Arctic waters. This study challenges previous assumptions about summer-dominated emissions and highlights the critical role of seasonal ice retreat. Dr. Else also contributed to the landmark review "Polar oceans and sea ice in a changing climate" (2023, 36 citations), a Surface Ocean–Lower Atmosphere Study (SOLAS) synthesis that examines rapid environmental changes at both poles and their implications for ocean-atmosphere interactions. His work is instrumental in understanding how Arctic coastal systems respond to climate change, and his field-based approach—capturing data during ice melt and winter—fills crucial gaps in polar greenhouse gas budgets. Dr. Else’s research has significant implications for global climate models and Arctic policy.
