U.S.-Chile Cooperative Research on the late Cenozoic Paleoceanographic and Paleoclimatic Evolution of Northern and Central Chile

0203555伊什曼这个美洲奖将支持斯科特E。南伊利诺伊大学卡本代尔分校的Ishman和Nicholas Pinter、智利大学的雅各布斯Le Roux博士、安托法加斯塔天主教大学的Guillermo Chong博士和国家自然历史博物馆的Ruben Martinez-Pardo博士，以表彰他们在智利北方和中部新生代古海洋学和古气候演变方面的工作。 该项目将在北部靠近安托法加斯塔的梅希约内斯半岛地区和智利中部圣地亚哥西南部的纳维达地区进行，智利的北方地区提供了一个独特的地理环境，可以调查南太平洋东部对从海平面记录解释的南极冰量变化的重大变化的海洋学和气候敏感性。 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。

0203555IshmanThis Americas award will support collaborative research between Drs. Scott E. Ishman and Nicholas Pinter of Southern Illinois University-Carbondale and Dr. Jacobus Le Roux, University of Chile, Dr. Guillermo Chong, Catholic University of Antofagasta, and Dr. Ruben Martinez-Pardo, National Museum of Natural History for their work on the Cenozoic Paleoceanographic and paleoclimatic evolution of Northern and Central Chile. The project will be done in the Mejillones Peninsula (MP) region in the north near Antofagasta and the Navidad region in central Chile to the southwest of Santiago.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.
