High-resolution continuous-flow analysis setup for water isotopic measurement from ice cores using laser spectroscopy
Here we present an experimental setup for water stable isotope (δO and δD) continuous-flow measurements and provide metrics defining the performance of the setup during a major ice core measurement campaign (Roosevelt Island Climate Evolution; RICE). We also use the metrics to compare alternate systems. Our setup is the first continuousflow laser spectroscopy system that is using off-axis integ...
متن کاملHigh speed, high resolution, and continuous chemical analysis of ice cores using a melter and ion chromatography.
Measurement of trace chemical impurities in ice cores contributes to the reconstruction of records of the atmospheric environment and of the climate system. Ion chromatography (IC) is an effective analytical technique for ionic species in ice cores but has been used on discretely prepared ice samples, resulting in extensive and slow sample preparation and potential for contamination. A new tech...
متن کاملVanillic acid in polar ice cores
This discussion paper is/has been under review for the journal Climate of the Past (CP). Please refer to the corresponding final paper in CP if available. Abstract Biomass burning generates a wide range of organic compounds that are transported via aerosols to the polar ice sheets. Vanillic acid is a product of conifer lignin combustion , which has previously been observed in laboratory and amb...
متن کاملA method for analysis of vanillic acid in polar ice cores
Biomass burning generates a wide range of organic compounds that are transported via aerosols to the polar ice sheets. Vanillic acid is a product of conifer lignin combustion, which has previously been observed in laboratory and ambient biomass burning aerosols. In this study a method was developed for analysis of vanillic acid in melted polar ice core samples. Vanillic acid was chromatographic...
متن کاملFrom Polar Ice Cores to Better Climate Models ?
Thomas Stocker, Professor of Climate and Environmental Physics and Co-Director of the Physics Institute at the University of Bern in Switzerland, spent his 2006 sabbatical at the IPRC. He worked with IPRC research team leader Axel Timmermann and postdoctoral fellow Oliver Timm on modeling the abrupt climate changes in the past that have resulted from changes in the Atlantic meridional overturni...
