Measurements of the fixation of nitrogen by auroras and the chemical composition of snow at the south pole

Measurements were made of the chemical constituents to determine how much nitrogen is fixed by auroral air glow and solar particulate bombardment. Other constituents were also determined to discover how much material reaches this point from the sea.

This is of interest in interpreting the atmospheric contribution to the centres of other continents where the position is confused by biological contamination and cyclic dust, both of which are absent at the South Pole.
