The concentration variation features of sea salt ions and non sea salt ions in a firn recovered from Princess Elizabeth Land, East Antarctica
A 51.85m firn core drilled in Princess Elizabeth Land, Antarctica, during the 1996-1997 Chinese First Antarctic Inland Expedition, has been measured for δ(18) and major ions. Based on the high quality data of the seasonal variations of major ions, the firn core was dated with errors within ±3 years....
