It is widely acknowledged that the Arctic Ocean plays an important role in regulating global climate. However, there is a striking paucity of paleo-climate records for this sensitive area. Funds are provided to core and investigate selected seafloor targets in the Arctic Ocean as part of a trans-Arctic crossing by the Swedish icebreaker, Oden and the USCGC Healy in 2005. This research will establish a pan-Arctic stratigraphic and paleoclimate record back to, at least, the last major interglacial, with special emphasis on the Chukchi region north of Alaska. Acoustical surveys will permit locating sites with high sedimentation rates. The initial post-cruise work will focus on core characterization. Data will be shared with European colleagues funded through other agencies.

人们普遍认为，北冰洋在调节全球气候方面发挥着重要作用。然而，这一敏感地区的古气候记录却少得惊人。作为瑞典破冰船奥登号和USCGC Healy号2005年跨北极航行的一部分，向北冰洋选定的海底目标提供了核心和调查资金。这项研究将建立一个泛北极地层和古气候记录，至少可以追溯到最后一个主要的间冰期，特别是阿拉斯加北部的楚科奇地区。声学勘测将可以确定沉降率较高的地点。最初的巡航后工作将集中在核心特征上。数据将与通过其他机构资助的欧洲同事共享。
