About
Cara C. Manning is a biogeochemist whose research illuminates the critical role of Arctic coastal systems in the global greenhouse gas cycle. Her work focuses on quantifying the fluxes of methane (CH₄) and carbon dioxide (CO₂) from rivers and estuaries, particularly during understudied seasons like ice melt. Manning’s most influential contribution is her 2020 study, “River Inflow Dominates Methane Emissions in an Arctic Coastal System” (57 citations), which provided the first year-round time series of dissolved methane in a Canadian Arctic estuary. This work demonstrated that river inflow, not in-situ production, is the primary driver of methane emissions during the spring freshet—a finding that challenges previous assumptions about Arctic carbon budgets. Her complementary 2019 study extended this analysis to include nitrous oxide (N₂O), further highlighting the complexity of polar greenhouse gas dynamics. By capturing data during the critical ice-retreat period—a time often missed by summer-only campaigns—Manning has provided essential baseline measurements for modeling Arctic responses to climate change. Her research is vital for understanding how warming temperatures and shifting hydrology will alter the Arctic’s role as a carbon source or sink.
