“…Overall, GHG fluxes in BCEs need more attention given that they are not often assessed and are difficult to quantify, as lateral exchange in these open systems can remove large amounts of GHGs in dissolved form during high tide and via porewater exchange (Fuentes & Barr, ; Maher, Santos, Golsby‐Smith, Gleeson, & Eyre, ; Santos, Maher, Larkin, Webb, & Sanders, ; Sippo et al, ). Studies concentrating on surface‐to‐atmosphere GHG exchange will therefore not be able to accurately capture sediment carbon cycling, a factor which is as of yet largely unaccounted for in BCE monitoring (but see Maher, Call, Santos, & Sanders, ).…”
