Abstract

Arctic soil organic carbon (SOC), the largest terrestrial organic carbon reservoir (Tarnocai et al., 2009; Schuur et al., 2015), is typically locked up in permafrost (Tarnocai et al., 2009; Olefeldt et al., 2016; Turetsky et al., 2020), but is under threat. The mean annual air temperature in the Arctic is rising twice as fast as the global average (Schuur et al., 2015). Permafrost will further degrade, exposing significant quantities of SOC to decomposition and respiration, releasing greenhouse gases (GHG), like CO2 and CH4, into the atmosphere (Walter et al., 2006; Mackelprang et al., 2011; Cory et al., 2014; Turetsky et al., 2020), driving a feedback loop of increasing air temperatures and degrading permafrost (Schuur et al., 2015).
