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

0203555伊什曼美洲奖将支持南伊利诺伊大学卡本代尔分校的Scott E.Ishman博士和Nicholas Pint博士与智利大学的Jacobus 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博士就智利北部和中部新生代古海洋和古气候演变所做的工作进行合作研究。该项目将在智利北部安托法加斯塔附近的梅吉洛内斯半岛(MP)地区和圣地亚哥西南部智利中部的纳维达德地区进行。智利北部地区提供了独特的地理环境，以调查南太平洋东部对根据海平面记录解释的南极冰量显著变化的海洋学和气候敏感性。梅吉洛内斯盆地是进行这项研究的理想之地。它代表了在活动边缘发展起来的浅海环境，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有助于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现象等反复发生的海洋和气象事件的影响，这些事件具有全球和经济意义。

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.
