ADCP oceanic current under drifting pack ice in central Arctic

Horizontal velocities were obtained using an acoustic Doppler current profiler (ADCP) (1MHz Signature 1000, Nortek) during 'ArcWatch-1' expedition. The ADCP was deployed on the ice floe #3 through a hydrohole. The three-dimensional velocities were collected for the duration of a few days at a rate of every second during a burst interval of 1 min, occurring at a sampling frequency of 10 min. The vertical extent of ADCP current data ranged from 1 to 20 m from the ice bottom, with data distributed at a 1 m vertical resolution.本数据集的水平流速数据通过声学多普勒流速剖面仪（acoustic Doppler current profiler，ADCP）（型号为1MHz Signature 1000，Nortek公司）于‘ArcWatch-1’科考航次中采集得到。该ADCP通过冰洞部署于3号浮冰之上。本次数据采集为期数天，采样周期为10分钟，每次突发采样时长为1分钟，突发采样期间以每秒1次的速率采集三维流速数据。ADCP海流数据的垂直覆盖范围为距冰底1至20米，数据以1米的垂直分辨率进行分布。
