The amount of methane released to the atmosphere from Nord Stream subsea pipeline leaks remains uncertain, as reflected in a wide range estimates1–18. A lack information regarding temporal variation atmospheric emissions has made it challenging reconcile volumetric (bottom-up) estimates1–8 with measurement-based (top-down) estimates8–18. Here we simulate rupture emission rates and integrate these dissolution sea-surface outgassing estimates9,10 model evolution leaks. We verify our modelled...
