"abstract": "Ice wedge degradation is a widespread occurrence across the circumpolar Arctic causing extreme spatial heterogeneity in water distribution, vegetation, and energy balance across landscapes. These heterogeneities influence carbon dioxide (CO2) and methane (CH4) fluxes, yet there is little understanding of how they effect change in landscape\u2010level carbon (C) gas flux over time. We measured CO2\u00a0and CH4\u00a0fluxes in an area undergoing ice wedge degradation near Prudhoe Bay, Alaska, and combined with repeat imagery analysis to estimate seasonal landscape\u2010level C flux response to geomorphic change. Net CO2\u00a0and CH4\u00a0emissions changed by \u221225% and\u00a0+42%, respectively, resulting in a 14% increase in seasonal CO2\u2010C equivalent emissions over 69\u00a0years as ice wedge degradation formed water\u2010filled troughs. The dynamic ice wedge degradation/stabilization process can cause significant changes in CO2\u00a0and CH4\u00a0fluxes over time, and the integration of this process is important to forecasting landscape\u2010level C fluxes in permafrost regions abundant in ice wedges.",
