WAIS Divide ice core chemistry 2710 to 1300 m depth
Listed in NASA Earthdata CMR
A continuous analytical system was used to analyze longitudinal samples from the WAIS Divide (79 28 5S, 112 4 1W, 1759 m)deep ice core between 1300 and 2710 m depth corresponding to ~6000 to ~27000 years before present.
Description
Analytical instruments included two high-resolution Inductively Coupled Plasma Mass Specrometers operating in parallel, a black carbon analyzer, and a number of spectrophotometers and fluorimeters. Analytes included a range of elements (e.g., Na,Mg,S,Ca,Sr,Ce)and chemical species (e.g., NH4, NO3-).
