  • Carbon burial offsets by CH 4 emissions should therefore be highest at midlatitudes, where burial rates were ~200 g C m −2 year −1 and CH 4 emissions were ~800 μmol m −2 day −1 . Measurements of carbon burial rates, sediment, and water CH 4 emissions are available for the same mangrove system in southern Moreton Bay (Australia) (23, 42).
