Raw data of SCADCP (self-contained Acoustic Doppler Current Profiler) from mooring AWI229-6

The ADCP used was of the type RDI Workhorse Longranger (Teledyne RD Instruments USA, Poway, California), using a four-beam, convex configuration with a beam angle of 20° and a frequency of 76.8 kHz. The instrument was moored at mean depth of 347 m in upward-looking mode and measured horizontal and vertical currents and acoustic backscatter intensity. Heading, pitch and roll, pressure and temperature data were also collected. The number of depth cells was set to 38 with a bin size of 16 m. The sampling interval was set to 1 ping per ensemble with a ping rate of about 1 ping every 10 minutes. The mooring AWI229-6 was deployed in February 2005 during R. V. Polarstern cruise ANT-XXII/3 and recovered during R. V. Polarstern cruise ANT-XXIII/2 in December 2005. […]

本次使用的声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）型号为RDI Workhorse Longranger（美国Teledyne RD Instruments公司，加利福尼亚州波威市），采用四波束凸面配置，波束角为20°，工作频率为76.8 kHz。该仪器以朝上观测模式布放于平均水深347 m处，可测量水平与垂向流速以及声学背散射强度，同时采集了航向、俯仰角、横滚角、压力及温度数据。深度单元总数设置为38个，单元间距为16 m。采样间隔设置为每个采样组包含1个声脉冲，脉冲重复频率约为每10分钟1次。锚系站位AWI229-6于2005年2月随极星号（R. V. Polarstern）科考航次ANT-XXII/3布放，并于2005年12月随极星号科考航次ANT-XXIII/2回收。[…]
