In summer 2005, two pilot snow/firn cores were obtained at 5365 and 5206 m a.s.l. on Fedchenko Glacier, Pamirs, Tajikistan, the world's longest and deepest alpine glacier. High-resolution Major and Trace Element data were measured on the two cores, from the upper accumulation zone of the Pamir. Fedchenko Glacier ice cores: Core 1: 38.55°N, 72.26°E, 5365m elev., 12.58m core length Core 2: 38.55°N, 72.26°E, 5206m elev., 9.14m core length
