West Antarctica's sensitivity to natural and human‐forced climate change over the Holocene

Journal of Quaternary Science (2012)

Paul A. Mayewski Kirk A. Maasch Simon Dixon Sharon B. Sneed Robert J. Oglesby

Abstract The location and intensity of the austral westerlies strongly influence southern hemisphere precipitation and heat transport with consequences for human society and ecosystems. With future warming, global climate models project increased aridity in southern mid‐latitudes related to continued poleward contraction of the austral westerlies. We utilize Antarctic ice cores to investigate past and to set the stage for the prediction of future behaviour of the westerlies. We show that Holocene West Antarctic ice core reconstructions of atmospheric circulation sensitively record naturally forced progressive as well as abrupt changes. We also show that recent poleward migration of the westerlies coincident with increased emission of greenhouse gases and the Antarctic ozone hole has led to unprecedented penetration, compared with >100,000 years ago, of air masses bringing warmth, extra‐Antarctic source dust and anthropogenic pollutants into West Antarctica.

Monitoring Of Trace Gas Emissions From Space: Tropospheric Abundances Of BrO, NO2, H2CO, SO2, H2O And O4 As Measured By GOME

WIT Transactions on Ecology and the Environment (2002)

Thomas Wagner Steffen Beirle C. von Friedeburg J. Hollwedel Stefan Kraus

The Global Ozone Monitoring Experiment (GOME) was launched in April 1995 and is since then continuously operating. GOME consists of four separate channels covering the spectral range from 240 to 790 nm with a moderate spectral resolution of 0.2 to 0.4 nm (FWHM). Originally designed for the measurement of ozone it was also possible to identify a large variety of trace gas absorption of additional atmospheric species in the spectrp recorded by GOME. These include several species which are located mostly or at least partly in the troposphere like BrO, N02, HCHO, S02, and H20, 02, and 04. Here we present an overview on the analysis and the interpretation of these measurements. While some products (like BrO and N02) are already analysed on a routine basis, some others like S02 and HCHO are investigated in case studies. Because of the large size of the ground pixels observed by GOME (40 x 320 km’) nearly all GOME measurements are at least partly cov~red by clouds which strongly affect the analysis of the tropospheric absorbefs! Examples of a cloud correction based on several parameters measured by GOME including e.g. the absorption of atmospheric oxygen (OJ and the oxygen dimer (OJ are presented.

Serpentinites and chromitites from La Cabaña, Coastal Range of Central Chile.

Andean geology (2010)

Las serpentinitas del area de La Cabana forman parte de la Serie Occidental del Basamento Metamorfico de la Cordillera de la Costa de la IX Region y corresponden a dunitas de grano grueso parcial a totalmente serpentinizadas. Contienen cromita como mineral accesorio, la que generalmente esta alterada en grado variable a ferricromita. En cambio, las cromitas presentes en las cromititas de Centinela Bajo, preservan su composicion original con un minimo grado de alteracion, lo que permite su uso como indicadores petrotectonicos. Sus valores de 'numero de cromo' (#Cr= Cr/Cr+Al) entre 0,65 y 0,90, de 'numero de magnesio' (#Mg=Mg/ Mg+Fe+2) entre 0,40 y 0,70, indican un ambito de arco de islas para el emplazamiento de las peridotitas estudiadas.
