智力优势:PI将收集样品,以扩大南极洲詹姆斯罗斯盆地晚白垩世沉积物的磁性地层记录。迅速的支持将使他能够利用南极研究所的邀请,参加到南极半岛的詹姆斯罗斯岛的旅行。PI希望收集样本,以改善白垩纪长正常Chron结束和Chron 31R下部之间的几次地磁反转的位置。这次考察的目标白兰地湾的地方是在盆地中校准的白垩纪长正常的Chron,这是在整个地质时间Scale.broader影响最可靠的相关视野的顶部的生物地层位置的最佳场所:白垩纪长正常的Chron的顶部是不正确相关的南半球生物地层。确定这一事件的位置将是了解地质时间的一个重要补充。这次探险将为本科生提供机会。该项目是在与一名阿根廷科学家进行富有成效的合作的基础上开展的。
英文摘要
Intellectual Merit: The PI will collect samples to extend the magneto-stratigraphic record of late Cretaceous sediments of the James Ross Basin, Antarctica. RAPID support will allow him to take advantage of an invitation from the Instituto Antartico Argentino (IAA) to participate on an excursion to James Ross Island in the Antarctic Peninsula. The PI hopes to collect samples that will refine the position of several geomagnetic reversals between the end of the Cretaceous long normal Chron and the lower portion of Chron 31R. The Brandy Bay locality targeted by this expedition is the best place in the basin for calibrating the biostratigraphic position of the top of the Cretaceous Long Normal Chron, which is one of the most reliable correlation horizons in the entire Geological Time Scale.Broader impacts: The top of the Cretaceous long normal Chron is not properly correlated to southern hemisphere biostratigraphy. Locating this event will be a major addition to understanding geological time. This expedition will provide opportunities for an undergraduate student. This project is based on a productive collaboration with an Argentine scientist.
