“…Over the past decade, several field studies reported methane release from the shallow seafloor of the Arctic Ocean (e.g., Mau et al, 2017; Shakhova et al, 2014, 2010; Thornton et al, 2016; Veloso‐Alarcón et al, 2019; Westbrook et al, 2009). Their sources, sinks, and potential connection to gas hydrate dissociation have been the focus of several follow‐up studies and discussions (Berndt, Dumke, et al, 2014; Berndt, Feseker, et al, 2014; Graves et al, 2017, 2015; James et al, 2016; Myhre et al, 2016; Platt et al, 2018; Riedel et al, 2018; Ruppel & Kessler, 2017; H. Sahling et al, 2014; Steinle et al, 2015; M Torres & Colwell, 2018; Wallmann et al, 2018). Different models have also been applied to investigate past, current, and future methane releases from the Arctic seafloor (Biastoch et al, 2011; Crémière et al, 2016; Marín‐Moreno et al, 2015, 2013; Reagan & Moridis, 2009; Thatcher et al, 2013).…”
