Arctic Marine Transportation Program 1979-1986, Version 1

The purpose of this program was to collect data relevant to developing year-round transportation capabilities in the Arctic Ocean. The US Maritime Administration sponsored this multi-year program to define environmental conditions in the Bering, Chukchi, and Beaufort Seas, to obtain data to improve design criteria for ice-worthy ships and offshore structures, and to demonstrate the operational feasibility of commercial icebreaking ships along possible future Arctic marine routes. The research was performed using the US Coast Guard Polar Star and Polar Sea ice-class ships, which were at the time the world's most powerful non-nuclear icebreakers and the only US ships capable of mid-winter Arctic operations.

The items in this data set are PDFs of Arctic Marine Transportation reports with embedded data, along with a PDF of the Achievement Record Brochure (Achievement_Record_1979_1984_Brochure.pdf), and JPEG images providing a historical context of the program. The 15 JPEG images and a PDF of accompanying captions (G02196_images_captions.pdf) are located in the images directory.

The PDF reports, an Executive Summary (Executive_Summary_Arctic_Marine_Transportation_Program.pdf), and the Appendix to the Executive Summary (Executive_Summary_Arctic_Marine_Transportation_Program_Appendix_A_List_of_Reports.pdf) are located in the Arctic_Marine_Transportation_Reports directory. Note that page 33 of the Executive Summary is missing. The Appendix to the Executive Summary contains an index of reports included in this data set. This index lists 64 reports, however, out of these 64, the following reports were never included and their location is unknown: 1, 4, 36, 37, 60, 61, and 62. Also note that reports 35 and 44 come in two parts.

The data cover the years 1979 to 1986 and were collected from ships in the Bering, Chukchi, and Beaufort Seas. Data are available via FTP.

This data is being provided as is. NOAA@NSIDC believes these data to be of value, but is unable to provide documentation. If you have information about this data set that others would find useful, please contact NSIDC User Services.

本项目旨在收集与开发北冰洋全年通航能力相关的数据。美国海事管理局（US Maritime Administration）赞助了这项多年期项目，旨在明确白令海、楚科奇海与波弗特海的环境条件，获取数据以优化适冰船舶与近海结构物的设计标准，并验证商业破冰船沿未来潜在北极远洋航线开展航行的作业可行性。该研究依托美国海岸警卫队"极地之星"号（Polar Star）与"极地海"号（Polar Sea）冰级破冰船开展，这两艘船在当时是全球功率最强的非核动力破冰船，也是美国仅有的可在北极冬季中期开展作业的船舶。

本数据集包含内嵌数据的北极远洋运输研究报告PDF文件，以及一份《成果记录手册》（Achievement_Record_1979_1984_Brochure.pdf），另有用于展现本项目历史背景的JPEG图像。15张JPEG图像及配套说明文档PDF（G02196_images_captions.pdf）存放于images目录下。

PDF研究报告、一份执行摘要（Executive_Summary_Arctic_Marine_Transportation_Program.pdf）及其附录（Executive_Summary_Arctic_Marine_Transportation_Program_Appendix_A_List_of_Reports.pdf）存放于Arctic_Marine_Transportation_Reports目录下。请注意，执行摘要的第33页缺失。该执行摘要附录包含本数据集收录报告的索引，该索引共列出64份报告，但其中编号为1、4、36、37、60、61及62的7份报告从未被纳入数据集，且其下落不明。此外，编号35与44的报告分为两个部分。

本数据集涵盖1979年至1986年的数据，采集自白令海、楚科奇海与波弗特海的作业船舶。数据可通过FTP协议获取。

本数据集按"现状"提供。美国国家海洋和大气管理局（NOAA）下属的美国国家冰雪数据中心（NSIDC）认为这些数据具有较高价值，但无法提供相关文档说明。若您掌握有助于其他用户了解本数据集的信息，请联系NSIDC用户服务部门。
