The Chemical and Isotopic Characteristics of Some Northeast Greenland Surface and Pingo Waters

Abstract

Water samples have been collected in Scoresby Land, northeast Greenland, from glacier, meltwater, stream, river, and pingo sources in the Delta Dal; from pingo sources in the Schuchert Dal and on Traill Island; and from fiords adjoining these areas. The samples were analyzed chemically for their principal solute ions, and isotopically for their deuterium and oxygen-18 contents. The combined results are examined in an attempt to elucidate the origins of waters from individual sources, with particular reference to the problem of pingo genesis. It is concluded that all the waters discharging from these pingos are of recent meteoric origin, and that waters discharging from a group of related pingos do not necessarily have a common aquifer source.
