Ice Draft and Ice Velocity Data in the Beaufort Sea, 1990-2003, Version 1

This data set provides measurement of sea ice draft (m) and the movement of sea ice (cm/s) over the continental shelf of the Eastern Beaufort Sea. The data set spans April 1990 to September 2003. The data set was acquired to assist in determining the character and recurrence of ice features hazardous to offshore industrial activity, specifically for the exploitation of hydrocarbon reserves and the impact of climate variability and change on the Beaufort Sea ice regime. Observations were made using two types of self-contained Upward Looking Sonar (ULS) moored near the sea floor: an Ice Profiling Sonar (IPS) used to obtain ice draft data and an Acoustic Doppler Current Profiler (ADCP) used to obtain the ice velocity data.

本数据集提供东波弗特海 (Eastern Beaufort Sea) 大陆架海域的海冰吃水 (sea ice draft，单位：米，m) 与海冰运动速度 (单位：厘米每秒，cm/s) 测量数据。本数据集的时间跨度为1990年4月至2003年9月。本数据集的采集旨在助力研判对近海工业活动存在威胁的冰体特征的类型与重现周期，具体服务于油气储量开发，以及评估气候变率与气候变化对波弗特海冰况的影响。观测采用两种部署于海底附近的自主式向上观测声呐 (Upward Looking Sonar, ULS) 完成：其中冰剖面声呐 (Ice Profiling Sonar, IPS) 用于采集海冰吃水数据，声学多普勒流速剖面仪 (Acoustic Doppler Current Profiler, ADCP) 则用于获取海冰运动速度数据。
