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，这个敏感地区的古气候记录却极其缺乏。 作为瑞典破冰船 Oden 和 USCGC Healy 于 2005 年跨北极穿越的一部分，提供资金对北冰洋选定的海底目标进行取芯和调查。这项研究将建立泛北极地层和古气候记录，至少可追溯到最后一个主要间冰期，特别关注阿拉斯加北部的楚科奇地区。 声学调查将允许定位具有高沉积率的地点。 最初的巡航后工作将侧重于核心特征。 数据将与通过其他机构资助的欧洲同事共享。
