Deskripsi

Oxygen contained within cosmic spherules is sourced from the atmosphere, making micrometeorites a possible archive for past atmospheric conditions. Here, Packet al. compare the isotopic composition of oxygen in cosmic spherules from Antarctica with that of the troposphere, and validate the value of this archive.
