SGER - µ-Raman Analysis of Ice-Core Samples
Entry ID: barletta_0828786

Abstract: Analysis of material preserved in glaciers and ice-sheets can provide a window into the climatological and environmental history of our planet. Current analytical methodology involves sectioning of core samples followed by destructive analysis, precluding simultaneous analysis of the same ice sample for microbial, and chemical content. Sample sizes required for each of these analyses limit the ... View entire text

Purpose: This project is a novel extension of Raman into the area of polar and climatic research, providing data on chemical speciation hitherto unavailable of critical importance to the understanding of the biology present in glacial ice as well as the sources of particulate material found in ice cores. Since the availability of ice-core material at critical horizons is limited, this non-destructive technique helps to maximize the information obtained from these samples. The application of µ-Raman spectroscopy to the analytical problems of trace environmental analysis at this level of spatial resolution is unique, and demonstrates the feasibility an integrated approach to ice core analysis, while addressing specific problems in glaciology.
