Ice Core Records of Recent Climatic Variability: Grigoriev
Ice cores, 16.5 and 20-meters in length, were recovered under the auspices of a cooperative USSR US glaciological research program on the Grigoriev and It-Tish ice caps in the Tien Shan, Central Asia. These have been analyzed for microparticle concentrations and size distributions, stable isotopic ratios (o18Q and 80), selected chemical species, and Beta radioactivity. The 1)18Q records reveal ...
متن کاملFour Centuries of Climatic Variation across the Tibetan Plateau from Ice- Core Accumulation and 80 Records
The Tibetan Plateau is an important component of the South Asian Monsoon system, but there are relatively few long, high-resolution records of precipitation and temperature variability from the Plateau itself. Only recently has it been recognized that the distribution and the chemistry of the precipitation across this large, elevated landmass is not unifonn (AraguasAraguas et al. , 1999; Tian e...
متن کاملSeasonal Deuterium Excess in a Tien Shan Ice Core: Influence of Moisture Transport and Recycling in Central Asia
[1] Stable water isotope (dO, dD) data from a high elevation (5100 masl) ice core recovered from the Tien Shan Mountains, Kyrgyzstan, display a seasonal cycle in deuterium excess (d = dD 8*dO) related to changes in the regional hydrologic cycle during 1994–2000. While there is a strong correlation (r = 0.98) between dO and dD in the ice core samples, the regression slope (6.9) and mean d value ...
متن کاملSynchronization of ice core records via atmospheric gases
To interpret new high resolution climate records it becomes more and more important to know about the succession of climate events. Such knowledge is hard to get especially when dealing with different types of climate archives. Even for ice cores a direct synchronization between ice cores from Greenland and Antarctica has not been pos-5 sible so far due to the lack of time markers occurring in ...
متن کاملReconstructing interannual climate variability from tropical and subtropical ice-core records
The patterns and sources of interannual, decadal, and century-scale climatic and environmental variability are of greatest relevance to human activities. Ice-core records from tropical and subtropical ice caps provide unique information about the chemical and physical character of the atmosphere. Annual variations in the amount and chemical composition of precipitation accumulating on these ice...
