This is a collaborative proposal among several institutions including the Universities of Colorado and Kansas. The Principal Investigators request funds to support the participation of U.S. scientists in the NEEM Project for the International Polar Year (IPY) to drill new deep ice core in northern Greenland to address past and future environments and climates. Specific goals will include obtaining a record of the climate of last interglacial period, the Eemain. This period was warmer than today and is the best analog for potential future climate. This core and the radar mapping will provide constraints on the size of the Greenland ice sheet when sea level was many meters higher than today. This core should reveal if abrupt climate change occurred in the Eemian period. Such information should offer better future predictive power for abrupt climate shifts and add to the growing knowledge about how alterations of climate and the environment by humans fit within the context of natural climate change. NEEM is an international effort, led by the glaciology group at the University of Copenhagen. Fifteen countries have expressed a desire to participate. The original proposal was reduced to funding the lead Principal Investigator, Dr. James White for travel and planning meetings as a placeholder" until the NEEM core is drilled. Dr. Claude Laird's radar project will be mainly supported by the NSF's CReSIS (STC) Program. The proposal, as submitted, is premature and will not be funded until the core is retrieved and it is certain that high quality Eemian ice has been drilled, otherwise this will be just another deep Greenland core with nothing new or different from the GISP2 or GRIP cores. The Danes have just received funding for the core, so the earliest the drilling could be staged is in 2007/2008 and the earliest the core could be retrieved through the Eemian is 2009. Dr. Laird will be funded because it is critical that the surface radar be done so that the best site can be chosen for the drilling.

这是科罗拉多大学和堪萨斯大学等多个机构之间的合作提案。首席研究员请求资金支持美国科学家参与国际极地年（IPY）的 NEEM 项目，在格陵兰岛北部钻探新的深冰芯，以解决过去和未来的环境和气候问题。具体目标将包括获得最后一个间冰期（Eemain）的气候记录。这一时期比今天温暖，是未来潜在气候的最佳模拟。当海平面比现在高出许多米时，该核心和雷达测绘将为格陵兰冰盖的大小提供限制。该核心应该揭示峨眉时期是否发生了气候突变。这些信息应该为未来气候突变提供更好的预测能力，并增加人们对人类对气候和环境的改变如何适应自然气候变化的认识。 NEEM 是由哥本哈根大学冰川学小组领导的一项国际努力。十五个国家表达了参与的愿望。最初的提案被缩减为资助首席研究员 James White 博士作为占位者进行旅行和计划会议，直到 NEEM 岩心钻探完毕。Claude Laird 博士的雷达项目将主要由 NSF 的 CReSIS (STC) 计划支持。该提案所提交的内容为时过早，只有在取回岩心并且确定已钻探出高质量的埃米亚冰之后才会获得资助，否则这将只是另一个深层次的研究 Greenland 核心与 GISP2 或 GRIP 核心没有任何新内容或不同之处。丹麦人刚刚获得了岩心的资助，因此最早可以在 2007/2008 年进行钻探，而通过埃米安岩心取回岩心的最早时间是 2009 年。莱尔德博士将获得资助，因为完成地面雷达工作至关重要，这样才能选择最佳的钻探地点。首席研究员请求资金支持美国的参与 国际极地年（IPY）NEEM项目的科学家们将在格陵兰岛北部钻探新的深冰芯，以应对过去和未来的环境和气候。具体目标将包括获得最后一个间冰期（Eemain）的气候记录。这一时期比今天温暖，是未来潜在气候的最佳模拟。当海平面比现在高出许多米时，该核心和雷达测绘将为格陵兰冰盖的大小提供限制。这个核心 应该揭示气候突变是否发生在温暖的峨眉时期。这些信息应该为未来气候突变提供更好的预测能力，并增加人们对人类对气候和环境的改变如何适应自然气候变化的认识。 NEEM 是由哥本哈根大学冰川学小组领导的一项国际努力。十五个国家表达了参与的愿望。最初的提议被简化为资助主要校长 研究员 James White 博士在 NEEM 核心钻探之前作为“占位者”负责旅行和计划会议。 Claude Laird 博士的雷达项目将主要得到 NSF 的 CReSIS (STC) 计划的支持。所提交的这项提案还为时过早，在取回岩心并且确定已钻探出高质量的埃米亚冰之前不会获得资助，否则这将只是另一个格陵兰深处的岩心，没有任何新的或独特的东西。 GISP2 或 GRIP 内核。丹麦人刚刚获得了岩心的资助，因此最早可以在 2007/2008 年进行钻探，而通过埃米安岩心取回岩心的最早时间是 2009 年。莱尔德博士将获得资助，因为完成地面雷达工作至关重要，这样才能选择最佳的钻探地点。
