Vanillic 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 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...
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 کاملGases in ice cores.
Air trapped in glacial ice offers a means of reconstructing variations in the concentrations of atmospheric gases over time scales ranging from anthropogenic (last 200 yr) to glacial/interglacial (hundreds of thousands of years). In this paper, we review the glaciological processes by which air is trapped in the ice and discuss processes that fractionate gases in ice cores relative to the conte...
متن کاملMicroparticle concentration variations linked with climatic change: evidence from polar ice cores.
The microparticle concentrations in three deep ice cores reveal a substantial increase in the concentration of insoluble particles in the global atmosphere during the latter part of the last major glaciation. The ratio of the average particle concentration in the late glacial strata to that in the Holocene strata is 6/1 for the core from Dome C, Antarctica, 3/1 for the core from Byrd Station, A...
