Abstract This project would address the Earth's most recent mass extinction ever, the K/T boundary, from the perspective of upper Cretaceous to lower Paleocene strata on James Ross and Seymour Islands, Antarctica. Its goal is to refine the magneto and chemostratigraphy for global correlations to determine the extinction's cause. While the K/T event is widely associated with a meteorite impact, there is some evidence that it may have been caused by global climate change. This field area may contain evidence that extinction in the high southern latitudes preceded that in more temperate locales, which would support a climactic origin. The broader impacts of this work include graduate education and dissemination of results through a popular science book.

摘要该项目将从上白垩纪至詹姆斯·罗斯（James Ross）和南极洲西摩群岛（Seymour Islands）上的白垩统到下古新世层的角度来解决地球最近的巨大灭绝，即K/T边界。它的目标是完善磁铁和化学地层学以确定灭绝的原因。尽管K/T事件与陨石的影响广泛相关，但有证据表明它可能是由全球气候变化引起的。该野外区域可能包含证据表明，高南纬度地区的灭绝是在更温和的地区，这将支持高潮起源。这项工作的更广泛影响包括研究生教育和通过流行的科学书籍传播结果。
