Abiotic nitrous oxide emission from the hypersaline Don Juan Pond in Antarctica

Abstract

Nitrous oxide is a potent atmospheric greenhouse gas1 that contributes to ozone destruction2. Biological processes such as nitrification and denitrification are thought to drive nitrous oxide production in soils, which comprise the largest source of nitrous oxide to the atmosphere1. Here we present measurements of the concentration and isotopic composition… (More)
