Impuretés solubles contenues dans la glace de l'Antarctique
International audience Ionic concentrations in the ice (down to 100 meters deep) and in the firn of the costal region of Term Adelie have been studied. The results show that the concentration found in the upper layers of the ice is sensibly the same as that found in locally accumulated layers of the...

International audience Ionic concentrations in the ice (down to 100 meters deep) and in the firn of the costal region of Term Adelie have been studied.

The principal ions, of which average concentration is always less than 1 mg/l, are in order of their importance C1, Na, and SO, and then K and Ca.
