Chemical and isotopic characteristics of a glacier-derived naled in front of Austre Grønfjordbreen, Svalbard
The chemical and stable isotope composition of a glacier-derived naled in front of the glacier Austre Grønfjordbreen, Svalbard, is examined to elucidate how secondary processes such as preferential retention and leaching affect naled chemistry. Internal candle ice layers have a chemical composition...
