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.

这个项目将从南极洲詹姆斯罗斯岛和西摩岛的上白垩纪到下古新世地层的角度，研究地球上最近的一次大灭绝，即K/T边界。它的目标是完善磁和化学地层学的全球相关性，以确定灭绝的原因。虽然K/T事件被广泛地与陨石撞击联系在一起，但有一些证据表明，它可能是由全球气候变化引起的。该地区可能包含证据表明，在南方高纬度地区的灭绝先于温带地区，这将支持气候起源。这项工作的更广泛影响包括研究生教育和通过科普书籍传播结果。
