Short summary
Methyl halides, compounds that contribute to stratospheric ozone destruction, have both anthropogenic and natural sources, but their natural sources are poorly characterized. The manuscript reports large emissions of methyl chloride and methyl bromide from subtropical salt marshes on the Gulf Coast of Texas, USA. The emission rates, including some of the largest observed from a natural source, contrast the much lower emission rates reported from higher-latitude salt marshes.
