Isotopic and related studies of antarctic ice samples
The ice samples obtained from Dakshin Gangotri, Antarctica show the presence of nuclear debris, attributed mainly to French nuclear explosions. Cosmogenic7Be occurs at levels of 30 dpm/L. The vertical profile ofdD in 6 m long drill core ranges between -130 and -180% compared to Standard Mean Ocean W...

The ice samples obtained from Dakshin Gangotri, Antarctica show the presence of nuclear debris, attributed mainly to French nuclear explosions. Cosmogenic7Be occurs at levels of 30 dpm/L. The vertical profile ofdD in 6 m long drill core ranges between -130 and -180% compared to Standard Mean Ocean Water (SMOW). No systematic change with depth is seen. Small amounts of dust obtained by filtering melt water show presence of metallic spherules. Absence of elements characteristic of meteoritic or cometary debris suggests that most of them are of volcanic or industrial origin. |
