Collaborative Research: Trans-Arctic 2005 Expedition for Development of a Pan-Arctic Stratigraphy and Paleoclimate Record

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非常缺乏。 作为瑞典“奥登”号破冰船和美国海岸警卫队“希利”号2005年跨北极航行的一部分，提供了资金，用于对北冰洋选定的海底目标进行取样和调查。 这项研究将建立一个泛北极的地层和古气候记录，至少可以追溯到最后一个主要的间冰期，特别强调阿拉斯加北部的楚科奇地区。 声学勘测将能够确定沉积率高的地点。 巡航考察后的初步工作将侧重于确定核心特征。 数据将与通过其他机构资助的欧洲同事共享。

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.
