项目摘要
ABSTRACTThe Uinta Mountains contain a well-preserved record of alpine glacier extents and behavior during the latestPleistocene. Yet, this record has not been studied in detail at the range-wide scale, and the timing of the Last GlacialMaximum (LGM) and subsequent deglaciation have not been determined. Documenting the spatial and temporalextent of late-Quaternary glaciation in the Uinta range is warranted for several reasons. First, the location of the range - central among well-dated alpine glacial localities and adjacent to the eastern edge of the Lake Bonneville basin - provides great potential for examining the regional effect of Lake Bonneville on paleoclimate and glaciation in northeastern Utah. Second, the orientation of the Uinta range provides a unique opportunity to study a record of large glaciers that flowed both north and south within a single mountain range. Finally, the excellent preservation of moraines and resistant lithology of erratic boulders provides ideal targets for cosmogenic surface-exposure dating. We propose to use a combination of conventional and advanced research methods to study the late-Quaternary glacial and paleoclimate record of the Uinta Mountains in pursuit of the following goals:1) Determine the extent and timing of glaciation in the Uinta Mountains during and since the LGM. Thiseffort will involve (1) detailed field and air photograph mapping of the surficial geology of the south flank ofthe Uinta Mountains (2) cosmogenic surface-exposure dating of moraines deposited during the LGM in thewestern, central, and eastern Uintas and (3) retrieval and study of lake sediment cores from lakes dammed by recessional moraines across the north and south slopes of the range.2) Reconstruct the latest Pleistocene paleoclimate from glacial records across the Uinta Mountains. Becausethe extents of glaciers are a function of temperature and precipitation, glacial records are excellent proxies of climate change. We will use the geomorphic records of latest Pleistocene glaciers to validate numericalmodeling experiments that simulate glacier growth based on climate input parameters; this will allow for aunique determination of LGM paleoclimate in the Uinta Mountains.Broader ImpactsThe research outlined in this proposal will yield benefits beyond pursuit of the core scientific objectives. First, it will further the ongoing relationship between the Ashley National Forest (ANF) and UW-Madison. Due to rising public use and more intensive management of National Forests, supervisors of the ANF have developed a greater interest in the geologic history of forest land and have supported graduate student research in the Uinta Mountains for the past 8 years (e.g., Douglass, 2000; Munroe, 2001; Carson, 2003) and continue to support current graduate research (B. Laabs, this study; see letter of support). Second, Ph.D. student B. Laabs will participate in the new NSF Center for the Integration of Research Teaching and Learning (CIRTL), an NSF-sponsored program that was launched at the UW-Madison to prepare the next generation of college science professors. He will participate in CIRTL courses and workshops focused on the effective use of research methods to disseminate scientific knowledge in the college classroom. Laabs will be among the first graduate students to receive a certificate acknowledging preparation for a career in academia and bring the fruits of this NSF-UW-Madison partnership into the U.S. higher education system. Finally, J. Munroe (Middlebury College) has built upon his graduate work in the Uintas and has begun including undergraduates in his current research on the late Quaternary history of the area. The proposed research provides the opportunity for three senior geology majors to pursue undergraduate theses on facets of theoverall research objectives (see RUI impact statement for more information).
摘要尤因塔山脉保存了更新世晚期高山冰川范围和活动的完整记录。然而,这一记录尚未在广泛的范围内进行详细研究,末次盛冰期(LGM)和随后的冰川消退的时间尚未确定。记录晚第四纪冰川在Uinta山脉的时空范围有几个原因。首先,该范围的位置-中央之间的良好日期的高山冰川的地方和毗邻的东边缘的湖博内维尔盆地-提供了巨大的潜力,研究区域影响的湖博内维尔在东北部犹他州的古气候和冰川作用。其次,尤因塔山脉的方位为研究在一条山脉内南北流动的大型冰川的记录提供了一个独特的机会。最后,冰碛的良好保存和不稳定漂砾的抗岩性为宇宙成因的表面暴露测年提供了理想的目标。我们建议采用传统和先进的研究方法相结合的研究晚第四纪冰川和古气候记录的Uinta山追求以下目标:1)确定冰川的范围和时间在Uinta山在LGM期间和自LGM以来。这项工作将包括(1)详细的现场和航空照片测绘的表面地质的南翼的尤因塔山脉(2)宇宙成因表面曝光测年的冰碛沉积在末次冰期在西部,中部,(3)从横跨山脉南北坡的后退冰碛筑坝的湖泊中提取和研究湖泊沉积物岩心。重建最新的更新世古气候从冰川记录横跨Uinta山脉。因为冰川的范围是温度和降水量的函数,冰川记录是气候变化的最佳代理。我们将使用最新更新世冰川的地貌记录来验证基于气候输入参数模拟冰川生长的numericalmodeling实验;这将允许在Uinta Mountains.Broader ImpactsThe研究中概述的研究将产生超出追求核心科学目标的好处。首先,它将进一步之间的阿什利国家森林(ANF)和威斯康星大学麦迪逊分校正在进行的关系。由于国家森林的公共使用和更密集的管理不断增加,ANF的主管对林地的地质历史产生了更大的兴趣,并在过去8年中支持研究生在Uinta山脉进行研究(例如,道格拉斯,2000年;门罗,2001年;卡森,2003年),并继续支持目前的研究生研究(B。Laabs,这项研究;见支持信)。第二,博士。学生B。Laabs将参加新的NSF研究教学与学习整合中心(CIRTL),这是一个由NSF赞助的项目,在威斯康星大学麦迪逊分校启动,为下一代大学科学教授做准备。他将参加CIRTL课程和研讨会,重点是有效利用研究方法在大学课堂上传播科学知识。Laabs将成为首批获得学术生涯准备证书的研究生之一,并将NSF-UW-麦迪逊合作伙伴关系的成果带入美国高等教育体系。最后,J. Munroe(Middlebury College)建立在他在Uintas的研究生工作的基础上,并开始在他目前对该地区第四纪晚期历史的研究中包括本科生。拟议的研究提供了机会,三个高级地质专业追求本科论文的方面,整体研究目标(见RUI影响声明的更多信息)。
