Downward looking, ice-mounted ADCP data collection during the SIPEX II voyage of the Aurora Australis, 2012

A 600KHz Teledyne RDI Workhorse Sentinel ADCP was deployed through a 10inch auger hole, flush with the base of the ice, looking downwards. At ice stations 2, 3, and 4 the deployment locations was Ridge site 1, the ridge site closest to the ship.At ice station 7 there were 4 different deployment locations:- Transducer Hole A, by active ridge on 6th October 2012;- Trace Metal / Bio Site;- 100m Core site of ice-physics transect;- Transducer Hole A, re-drilled on 7th October 2012.Length of deployment varies from stations to station and was limited by AUV operations, when our ADCP was switched off. Files contain the data collected in raw format. This format can be read by Teledyne WinSC software. Data files are stored in folders by ice station (see below).

一台600kHz的Teledyne RDI Workhorse Sentinel型声学多普勒流速剖面仪（ADCP，Acoustic Doppler Current Profiler）通过10英寸螺旋钻孔部署，与冰盖底部齐平，向下开展探测。在冰站2、3和4中，部署位置均为海脊站点1——该海脊站点距离科考船最近。冰站7则设有4处不同的部署点位：2012年10月6日位于活跃海脊旁的换能器孔A、痕量金属/生物采样点、冰物理断面的100米岩芯采样点，以及2012年10月7日重新钻孔的换能器孔A。本次部署的时长因冰站不同而有所差异，受自主水下航行器（AUV，Autonomous Underwater Vehicle）作业限制，当该ADCP停机时，部署任务即告终止。采集的数据以原始格式存储于文件中，该格式可通过Teledyne WinSC软件读取。数据文件按照冰站分类存储于对应文件夹（详见下文）。
