ABSTRACTWernerOPP-0244097The Arctic Natural Sciences Program and Paleoclimate Program in the Division of Atmospheric Sciences are jointly funding this three-year project. Mount Holyoke College is the host institution in collaboration with Principal Investigators at the Universities of Massachusetts and Northern Illinois, Bates College, Hampshire College, and the Norwegian University system (UNIS) and the Norwegian Polar Institute. The Arctic is particularly sensitive to climate change and because climatically-induced environmental changes in this region can instigate further changes of global consequences. Svalbard has warmed considerably during the last 90 years and climate proxies indicate even greater Holocene climate change. Despite this, little is known of sub-century climate change and virtually nothing is known of decadal scale variability in this region. Undergraduate students will do research on glacial-lacustrine and glacio-marine systems in order to establish linkages between climate, glacier mass balance, sediment transport, and lake and fjord sedimentation. Selected undergraduate students will: 1) quantify the response of the glacial, fluvial, lacustrine, and fjord systems to measured weather fluctuations; and 2) use these relationships to calibrate and interpret sediment records from lakes and fjords to reconstruct Holocene climatic changes. Students, working closely with student colleagues and faculty mentors, will design their own research questions, collect field data, and formulate hypotheses and conclusions. They will spend five weeks on Svalbard which will include orientation, safety training, and fieldwork. They will complete their research at their home institutions during the following academic year and will be invited the following spring semester to participate in a project symposium. The objective of this REU Site program is to expose students to the challenges and rewards of polar research. Six research positions will available in summer, 2004 for highly motivated undergraduate students having a strong interest in polar science and climate change research. Underrepresented groups and students without research opportunities at their home institutions will be actively recruited. Research results from this project will be incorporated into undergraduate courses at all of the institutions, will be made available to the broader scientific community, and will be used in presentations on arctic climate change for public audiences.

大气科学部的北极自然科学计划和古气候计划联合资助了这个为期三年的项目。 蒙特霍利奥克学院是与马萨诸塞州和北方伊利诺伊大学、贝茨学院、汉普郡学院、挪威大学系统（UNIS）和挪威极地研究所的主要研究人员合作的主办机构。 北极对气候变化特别敏感，因为该地区气候引起的环境变化可能引发全球后果的进一步变化。 斯瓦尔巴特群岛在过去90年里已经大大变暖，气候代用指标表明全新世气候变化甚至更大。 尽管如此，人们对亚世纪气候变化知之甚少，对该地区的年代际尺度变化几乎一无所知。 本科生将对冰川湖泊和冰川海洋系统进行研究，以建立气候，冰川物质平衡，沉积物运输，湖泊和峡湾沉积之间的联系。 选定的本科生将：1）量化冰川，河流，湖泊和峡湾系统对测量的天气波动的响应; 2）使用这些关系来校准和解释湖泊和峡湾的沉积物记录，以重建全新世气候变化。 学生，与学生同事和教师导师密切合作，将设计自己的研究问题，收集现场数据，并制定假设和结论。他们将在斯瓦尔巴群岛度过五个星期，其中包括定向，安全培训和实地考察。 他们将在下一学年完成他们的研究在他们的家乡机构，并将被邀请参加下一个春季学期的项目研讨会。 这个REU网站计划的目标是让学生接触极地研究的挑战和回报。 2004年夏季将为对极地科学和气候变化研究有浓厚兴趣的积极性高的本科生提供六个研究职位。将积极招募代表性不足的群体和在本国机构没有研究机会的学生。 该项目的研究成果将纳入所有机构的本科课程，将提供给更广泛的科学界，并将用于向公众介绍北极气候变化。
