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

[19298 . Ishman]本美洲奖将支持南伊利诺伊大学卡本代尔分校的Scott E. Ishman博士的计划访问，以完成与Scott E. Ishman博士的合作研究项目。国家自然历史博物馆的鲁本·e·马丁内斯、圣佩德罗·诺拉斯科学院的鲁道夫·马丁内斯和丰克博物馆的路易斯·a·奇里诺，他们分别来自智利。研究人员将在智利的安托法加斯塔和圣地亚哥会面，并对智利梅吉罗内斯地区进行实地考察。智利北部地区为研究南太平洋东部的海洋学和气候敏感性提供了一个独特的地理环境，这是根据海平面记录解释的南极冰量变化的显著变化。梅吉罗内斯盆地是进行这项研究的理想地点。它代表了一个在活动边缘发育的浅海环境，附近有火山活动和其他重要的构造特征。该项目的研究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，以及它们对厄尔尼诺等具有全球和经济意义的反复出现的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.
