Collaborative Research: The Sedimentary Record of Tidewater Glacier Response to Holocene Climate Variability in the Antarctic Peninsula

该项目研究南极半岛的海洋沉积物岩心，以确定目前那里的冰架衰减是由全球变暖还是另一个循环引起的。一套全面的核心分析？从放射性碳到生物地层学？将用来描述过去两万年冰架的状态。这个项目吗?S的目标是评估冰架对海洋温度、降水和海冰范围等环境驱动因素的响应。这项研究得益于美国国家科学基金会最近支持的两次对该地区的考察，其中包括收集了长时间沉积物岩心的“shaldrill”。这些核心将支持开发高分辨率的半岛图片。冰川、气候和海洋学的历史。该项目的广泛影响包括研究生和本科生参与研究，支持早期职业研究人员，与主要本科院校合作，以及与英国和波兰科学家的国际合作。这对社会也有影响。因为这项工作提高了我们对冰盖行为及其与全球气候关系的理解。

This project studies marine sediment cores from the Antarctic peninsula to determine whether the current decay of ice shelves there is caused by global warming or another cycle. A comprehensive set of core analyses?from radiocarbon to biostratigraphy?will be performed to characterize ice-shelf status during the last 20,000 years. The project?s goal is to assess ice-shelf response to environmental drivers such as ocean temperature, precipitation, and sea ice extent. The study benefits from two, recent, NSF-supported expeditions to the area, including ShalDril, in which lengthy sediment cores were collected. These cores will support development of a high-resolution picture of the peninsula?s glacial, climactic, and oceanographic history. The broader impacts of this project include graduate and undergraduate participation in research, support for early career researchers, collaboration with primarily undergraduate institutions, and international collaboration with scientists in the UK and Poland. There are also implications for society?s understanding of climate change, since this work improves our understanding of the behavior of ice sheets and their links to global climate.
