Bacterial diversity of autotrophic enriched cultures from remote, glacial Antarctic, Alpine and Andean aerosol, snow and soil samples

Autor: E. González-Toril, R. Amils, R. J. Delmas, J.-R. Petit, J. Komárek, J. Elster

Publikováno v: Biogeosciences, Vol 6, Iss 1, Pp 33-44 (2009)

Four different communities and one culture of autotrophic microbial assemblages were obtained by incubation of samples collected from high elevation snow in the Alps (Mt. Blanc area) and the Andes (Nevado Illimani summit, Bolivia), from Antarctic aer

Trace elements in South America aerosol during 20th century inferred from a Nevado Illimani ice core, Eastern Bolivian Andes (6350 m asl)

Autor: A. Correia, R. Freydier, R. J. Delmas, J. C. Simões, J.-D. Taupin, B. Dupré, P. Artaxo

Publikováno v: Atmospheric Chemistry and Physics, Vol 3, Iss 5, Pp 1337-1352 (2003)

A 137 m ice core drilled in 1999 from Eastern Bolivian Andes at the summit of Nevado Illimani (16º 37' S, 67º 46' W, 6350 m asl) was analyzed at high temporal resolution, allowing a characterization of trace elements in Andean aerosol trapped in th

Volcanic eruptions recorded in the Illimani ice core (Bolivia): 1918–1998 and Tambora periods

Autor: M. De Angelis, J. Simões, H. Bonnaveira, J.-D. Taupin, R. J. Delmas

Publikováno v: Atmospheric Chemistry and Physics, Vol 3, Iss 5, Pp 1725-1741 (2003)

Acid layers of volcanic origin detected in polar snow and ice layers are commonly used to document past volcanic activity on a global scale or, conversely, to date polar ice cores. Although most cataclysmic eruptions of the last two centuries (Pinatu

First results of 15N/14N ratios in nitrate from alpine and polar ice cores

Autor: H. D. FREYER, K. KOBEL, R. J. DELMAS, D. KLEY, M. R. LEGRAND

Publikováno v: Tellus B; Vol 48, No 1 (1996)

Isotopic analyses of nitrogen were performed in nitrate from alpine and polar snow and ice. Nitrate from recent alpine ice cores showed similar 15N/14N ratios and seasonal variations as continental rain nitrate. Nitrate from recent Summit (Greenland)

The Late Quaternary History of Atmospheric Trace Gases and Aerosols: Interactions Between Climate and Biogeochemical Cycles

Autor: Dominique Raynaud, Yugo Ono, T. Blunier, R. J. Delmas

Publikováno v: Paleoclimate, Global Change and the Future ISBN: 9783642626920

Human activities perturb the atmosphere and thereby influence the global climate. Prominent examples are greenhouse trace gases and sulfate aerosols which both affect the radiative balance at the surface of the Earth. This is also true for black carb
