Ice core analysis of dissolved organic carbon (DOC) and monocarboxylic acids (RCOOH) over depth and time from the Mount Elbrus (ELB), Caucasus glacier site. ELB ice cores were analyzed using the low analyser for dissolved organic carbon and the ion chromatography system at the Institute of Environmental Geosciences. The detection limits, defined as 3 times the standard deviation of the blank, were 5 ppbC for DOC, and close to 0.1 ppb for monocarboxylates. In addition, the calculated water-soluble organic carbon (WSOC) is also given. Provided Keywords: Caucasus ice core, organic carbon aerosol, biogenic sources ABSTRACT SUPPLIED BY ORIGINATOR: To reconstruct the history of organic carbon (OC) aerosol over south-eastern Europe, dissolved organic carbon (DOC) and its 14C signature (DO14C) were investigated along an ice core drilled at the Mount Elbrus (ELB) in Caucasus. In summer, compared to pre-1945 levels, the DOC concentrations increased by 45% after 1960, the mean DO14C depletion in recent ELB ice relative to atmospheric 14CO2 of 32% being attributed to fossil-fuel sources. DO14C content of ice deposited during the bomb-peak era (1955–1980) closely followed atmospheric 14CO2 changes caused by atmospheric nuclear tests, suggesting the living biosphere as the main biogenic source of DOC in summer in this region. ELB data contrast with those previously obtained in summer Alpine (western Europe) ice in which a post-1950 doubling of DOC was observed and attributed to enhanced emissions of organic compounds from vegetation in France. This regional difference is discussed with respect to changes of biogenic organic compound emissions in response to past change of use-land and global warming. ELB data document, for the first time, changes of DOC and DO14C in winter mountain ice showing an increase by 44% of DOC levels associated with a 14C signature being 47% lower than that of atmospheric 14CO2 in ELB ice deposited after 1960. The 14C winter ELB ice record followed atmospheric 14CO2 changes with a delay of ~3 years, suggesting that remaining emissions from the living biosphere, together with a small contribution from wood burning, are the main biogenic sources of DOC in winter in this region.
