项目摘要
Intellectual Merit: The PIs propose to investigate last glacial maximum through Holocene glacial change on the northeastern Antarctic Peninsula, an area distinguished by dramatic ice shelf collapses and retreat of upstream glaciers. However, there is a lack of long-term context to know the relative significance of recent events over longer time scales. The PIs will obtain data on former ice margin positions, ice thicknesses, glacier retreat and thinning rates, and Holocene glacier change in the James Ross Island Archipelago and areas near the former Larsen-A ice shelf. These data include maximum- and minimum-limiting 14C and cosmogenic-nuclide exposure dates integrated with geomorphology and stratigraphy. Understanding the extent, nature, and history of glacial events is important for placing current changes in glacial extent into a long-term context. This research will also contribute to understanding the sensitivity of ice shelves and glaciers in this region to climate change. Records of changes in land-terminating glaciers will also address outstanding questions related to climate change since the LGM and through the Holocene. The PIs will collect samples during cooperative field projects with scientists of the Instituto Antártico Argentino and the Korea Polar Research Institute planned as part of existing, larger, research projects.Broader impacts: The proposed work includes collaborations with Argentina and Korea. The PIs are currently involved in or are initiating education and outreach activities that will be incorporated into this project. These include interactions with the American Museum of Natural History, the United States Military Academy at West Point, and undergraduate involvement in their laboratories. This project provides a significant opportunity to engage the public as it focuses on an area where environmental changes are the object of attention in the popular media.
学术价值:PIs建议在南极半岛东北部研究末次冰盛期到全新世的冰川变化,该地区以剧烈的冰架崩塌和上游冰川退缩为特征。然而,缺乏长期背景来了解近期事件在较长时间尺度上的相对重要性。pi将获得詹姆斯罗斯岛群岛和前拉森a冰架附近地区以前的冰缘位置、冰厚度、冰川退缩和变薄速度以及全新世冰川变化的数据。这些数据包括最大和最小限制14C和宇宙成因-核素暴露日期,并结合地貌和地层学。了解冰川事件的范围、性质和历史对于将当前冰川范围的变化置于长期背景下是很重要的。这项研究还将有助于了解该地区冰架和冰川对气候变化的敏感性。陆地末端冰川的变化记录也将解决自LGM以来和整个全新世有关气候变化的突出问题。pi将在与安泰研究所的科学家合作的实地项目中收集样本。rtico Argentino和韩国极地研究所计划将其作为现有的更大研究项目的一部分。更广泛的影响:拟议的工作包括与阿根廷和韩国的合作。私人机构目前正在参与或正在发起将纳入本项目的教育和外联活动。其中包括与美国自然历史博物馆、美国西点军校的互动,以及本科生参与他们的实验室。这个项目为公众提供了一个重要的机会,因为它关注的是一个环境变化是大众媒体关注的对象的地区。
