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

众所周知，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少得惊人。作为2005年瑞典破冰船“奥登”号和USCGC“希利”号穿越北极的一部分，为在北冰洋选定的海底目标进行核心和调查提供了资金。这项研究将建立一个至少追溯到最后一个主要间冰期的泛北极地层和古气候记录，特别强调阿拉斯加北部的楚科奇地区。声学测量可以确定高沉降率地点的位置。最初的巡航后工作将集中在核心特征上。数据将与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.
