We report on methane (CH 4) stable isotope (d 13 C and d 2 H) measurements from landfast sea ice collected near Barrow (Utqiagvik, Alaska) and Cape Evans (Antarctica) over the winter-to-spring transition. These measurements provide novel insights into pathways of CH 4 production and consumption in s...
