Reconnaissance Glacio-Chemical Studies In The Indian Himalayas, Paul Andrew Mayewski, William Berry Lyons, Nasseruddin Ahmad
Earth Science Faculty Scholarship
Analysis of reactive silicate, ammonium, phosphate, iron and sodium from cores taken from three glaciers in the Kashmir portion of the Himalayas are reported as the first in a series of glacio-chemical studies designed to produce proxy paleoclimatic data for this region. This study stresses the elevation dependency of such studies and for the chemical species analyzed which are most reliable for the purpose of the study.

Surface snows collected at various elevations in the Indian Himalayas were analyzed in the field for pH as part of a broader study of the chemistry. The pH values are lower than the predicted ≅5.6 for unpolluted precipitation. Analysis of NO3 + NO2, Cl, SO4 and NH4 indicate that these low pH values are not completely due to the presence of strong mineral acids. The strong correlation of pH with elevation (i.e. temperature) suggests that the low pH values are due to the snow being supersaturated with CO2.

[From the introduction] During the 1980-81 field season we conducted a two-part program: the first part was spent on the Rennick Glacier in northern Victoria Land, and the second in the ice-free valleys of southern Victoria Land. The primary objective of the program was to help elucidate the glacial and climatic history of Transantarctic Mountains ice masses by interpreting the records available from the spectrum true glaciers to rock glaciers.
