This award will help expand the temporal and spatial coverage of climate-sensitive tree-ring chronologies in the Gulf of Mexico region. These proxy climate records will be used with existing data to define decadal drought and wetness regimes over North America and examine its connections with climatic events and systems such as the El Nino Northern Oscillation, the Pacific Decadal Oscillation, and the North American Monsoon System.Paleoclimate data from Mexico will be examined for decadal climate variability. Tree-ring chronologies will be examined to reconstruct climate and climate related variables such as streamflow and crop yields. These records will be examined to assess the impact of climate extremes on past and current human cultures in the research area.This research will greatly expand the coverage of climate-sensitive tree-ring chronologies in the Gulf of Mexico region that will help document the existence and extent of many ancient forest remnants. The research will provide science experience and training for undergraduate and graduate students in the United States and Latin America and encourage research partnerships across national borders.

该奖项将有助于扩大墨西哥湾地区气候敏感树木年轮年表的时空覆盖范围。这些代用气候记录将与现有数据一起用于确定北美地区的十年干旱和湿润状况，并检查其与气候事件和系统（如厄尔尼诺北方涛动、太平洋年代际涛动和北美季风系统）的联系。将对墨西哥的古气候数据进行年代际气候变化研究。树木年轮年表将被检查重建气候和气候相关的变量，如河流和作物产量。研究人员将对这些记录进行检查，以评估极端气候对研究地区过去和现在人类文化的影响。这项研究将极大地扩大墨西哥湾地区对气候敏感的树木年轮年表的覆盖范围，这将有助于记录许多古代森林遗迹的存在和范围。这项研究将为美国和拉丁美洲的本科生和研究生提供科学经验和培训，并鼓励跨国界的研究伙伴关系。
