Glaciochemical Studies and Estimated Net Mass Balances for Rennick Glacier Area, Antarctica
Two snow and ice cores from the Rennick Glacier area, Antarctica (study area center point lat 71° 15' S, long 162° 30' E) were analyzed for the chemical species: chloride, sodium, reactive silicate, sulfate and nitrate. Core E1O (6.35 m) was taken from Evans Névé, a large accumulation basi...
