项目摘要

AbstractPI: John B. AndersonProposal Number: 0837925Title: History of, and Mechanisms Leading to, Post-LGM Retreat of the West Antarctic Ice SheetThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The West Antarctic Ice Sheet is believed to be vulnerable to climate change as it is grounded below sea level, is drained by rapidly flowing ice streams and is fringed by floating ice shelves subject to melting by incursions of relatively warm Antarctic circumpolar water. Currently, the most rapidly thinning glaciers in Antarctica occur in the Amundsen and Bellingshausen Sea sectors. This study seeks to place the present day observations into a longer-term geological context. Mechanisms that led to the retreat of the ice sheet from the West Antarctic continental shelf since the last glacial maximum will be investigated. This study will build on a number of previous investigations and fill in key data gaps in the region. Bathymetric mapping and direct sampling of relict glacial features on the continental shelves of the Bellingshausen (Marguerite Bay), Amundsen (Pine Island Bay) and eastern Ross Seas will be conducted via dedicated science time on the Swedish Icebreaker Oden. Sites for Kasten coring will be selected on the basis of detailed swath mapping. Radiocarbon dating of glaciomarine deposits in the new and existing cores will refine the timing of retreat events. Geomorphic features of paleo ice streams such as grounding line wedges and ice scours will be examined to assess whether the retreat occurred continuously and/or episodically. Sediments will be examined for paleontological evidence of warm ocean water intrusions during retreat as well as for mineral evidence of possible melt water origins.Broader impacts:This project is collaborative with colleagues from the US, Sweden, the UK, France, Japan and Poland. It will entail the training of three PhD students at Rice University and so afford them international field work experience. One of these will be transitioning to post-doc status in the course of this project. An undergraduate student will also be involved in the fieldwork phase of the research. The PI expects to continue to be active in Rice University's Houston area high school teacher outreach program as well as a separate program to convey science to elderly people confined in assisted living and retirement facilities.
摘要:约翰·B·安德森提议编号:0837925标题:西南极冰盖末次盛冰期后退缩的历史和机制该奖项由2009年《美国复苏和再投资法案》(公法111-5)资助。西南极冰盖被认为很容易受到气候变化的影响,因为它固定在海平面以下,被快速流动的冰流排干,并被漂浮的冰架环绕,这些冰架容易因相对温暖的南极环极海水的入侵而融化。目前,南极洲冰川变薄最快的地区是阿蒙森海和别林豪森海。这项研究试图将目前的观察放在更长期的地质背景下进行。将对自上一次冰川盛期以来导致西南极大陆架冰盖退缩的机制进行调查。这项研究将以以前的一些调查为基础,填补该区域的关键数据空白。对别林豪森(玛格丽特湾)、阿蒙森(松岛湾)和罗斯海东部大陆架上的残留冰川地貌进行水深测绘和直接采样将通过瑞典破冰船奥登上的专门科学时间进行。卡斯滕取心的选址将根据详细的条带测绘进行。对新的和现有的岩芯中的冰川玛利亚矿床进行放射性碳测年,将精炼出退缩事件的时间。将研究接地线楔形和冰川冲刷等古冰川的地貌特征,以评估退缩是否连续和/或断续发生。将对沉积物进行研究,以寻找在退缩过程中温暖的海水入侵的古生物学证据,以及可能来自融化水来源的矿物证据。广泛的影响:该项目与来自美国、瑞典、英国、法国、日本和波兰的同事合作。这将需要在莱斯大学培训三名博士生,从而为他们提供国际实地工作经验。其中之一将是在这个项目过程中过渡到博士后状态。一名本科生也将参与这项研究的实地考察阶段。PI预计将继续积极参与莱斯大学休斯顿地区的高中教师外展计划,以及一个单独的计划,向被限制在辅助生活和退休设施中的老年人传播科学。
