Multibeam bathymetry raw data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS124

Multibeam data were collected with RV Polarstern along the route of cruise PS124 and data acquisition was almost continuously monitored during the survey. Multibeam sonar system was Teledyne/Atlas Hydrosweep DS3. SVPs were retrieved from CTD data from other working groups on board. SVPs were processed with HydrOffice SoundSpeedManager (https://www.hydroffice.org/soundspeed/main) and extended with World Ocean Atlas 13 (https://doi.org/10.7289/v5f769gt). SVP data were applied during acquisition. Multibeam data are unprocessed and may contain outliers and blunders and should not be used for grid calculations and charting projects without further editing. The raw multibeam sonar data in Teledyne/Atlas multibeam processing format (.asd) were recorded with Teledyne/Atlas Parastore software as well as Teledyne Reson format (.s7k) in Teledyne PDS. Raw data files can be processed using software packages like CARIS HIPS/SIPS. For updated vessel configuration files check further details.

本数据集的多波束数据由极星号（RV Polarstern）科考船沿PS124航次航线采集，调查期间几乎全程对数据采集过程实施监控。本次采集采用的多波束声呐系统为Teledyne/Atlas Hydrosweep DS3。声速剖面（Sound Velocity Profile，SVP）数据由船上其他工作组的CTD（温盐深仪）数据提取获得。声速剖面数据经HydrOffice SoundSpeedManager（https://www.hydroffice.org/soundspeed/main）处理，并通过《世界海洋图集2013》（World Ocean Atlas 13，https://doi.org/10.7289/v5f769gt）进行扩展补充。采集过程中已应用上述声速剖面数据。本次多波束数据未经过预处理，可能存在异常值与粗差，未经进一步编辑不得用于格网计算与海图制图项目。原始多波束声呐数据分别以两种格式存储：Teledyne/Atlas多波束处理格式（.asd）通过Teledyne/Atlas Parastore软件记录，Teledyne Reson格式（.s7k）则存储于Teledyne PDS中。原始数据文件可通过CARIS HIPS/SIPS等软件包进行处理。如需获取更新后的船舶配置文件，请查阅相关详细说明。
