U.S.-Chile Program Planning Visit: Research on Late Cenozoic Paleoceanographic Evolution of Northern Chile

0119298伊什曼这个美洲奖将支持斯科特E.伊什曼与鲁本·E·卡宾达博士完成了一项合作研究项目。国家自然历史博物馆的马丁内斯、圣佩德罗诺拉斯科学院的鲁道夫马丁内斯和路易斯A。丰克博物馆的奇里诺，分别位于智利。 研究人员将在智利的安托法加斯塔和圣地亚哥举行会议，并将对智利的梅希隆地区进行实地考察。智利的北方地区提供了一个独特的地理环境，以调查南太平洋东部对南极冰量变化的海洋和气候敏感性。 Mejillones盆地是这项研究的理想地点。 它代表了在活动边缘上发育的浅海环境，附近有火山活动和其他重要的构造特征。 这一拟议项目的结果将使人们更好地了解南极冰量变化、海洋和大气环流之间的相互联系，以及这些变化对厄尔尼诺等具有全球和经济意义的经常性海洋和气象事件的影响。

0119298IshmanThis Americas award will support a planning visit by Dr. Scott E. Ishman of Southern Illinois University-Carbondale to finalize a cooperative research project with Drs. Ruben E. Martinez of the National Museum of Natural History, Rodolfo Martinez of San Pedro Nolasco College and Luis A. Chirino of Museo Fonck, all in Chile, respectively. The researchers will meet in Antofagasta and Santiago, Chile and will do site visits to localities in the Mejillones region of Chile.The northern region of Chile provides a unique geographic setting to investigate the oceanographic and climatic sensitivity of the eastern South Pacific to significant changes in Antarctic ice volume change as interpreted from sea-level records. The Mejillones Basin is ideal for this research. It represents a shallow marine setting developed on an active margin with nearby volcanism and other significant tectonic features. Results from this proposed project will provide a better understanding of the interconnection between Antarctic ice volume change, oceanographic and atmospheric circulation, and the impacts these have on recurring oceanographic and meteorological events such as El Nino, which have global and economic significance.
