Seasonal variations in the concentration of 10 Be, Cl - , NO 3 - , SO 4 2- , H 2 O 2 , 210 Pb, 3 H, mineral dust, and δ 18 O in Greenland snow
A detailed snow pit study at Dye 3, South Greenland, has been carried out in order to investigate the seasonal variations of 10 Be, Cl - , NO 3 - , SO 4 2- , H 2 O 2 , 210 Pb, 3 H, Mn and δ 18 O. Special emphasis was placed on understanding the causes of 10 Be variations because this isotope can be...
