Abiotic Nitrous Oxide Production From Sediments and Brine of Don Juan Pond, Wright Valley Antarctica, at Mars Analog Temperatures (−40°C)

The presence of biogenic gases such as oxygen, methane, and nitrous oxide (N2O) in the atmospheres of extraterrestrial bodies has been postulated as a biosignature of life. Abiotic N2O production was documented recently in Don Juan Pond (DJP), Antarctica, a cold, hypersaline Mars analog environment....
