Multibeam bathymetry raw data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS118

Multibeam data were collected with RV Polarstern along the route of cruise PS118 and data acquisition was 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. 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科考船（RV Polarstern）沿PS118航次航线采集，调查期间对数据采集过程实施了持续监测。所采用的多波束声呐系统为Teledyne/Atlas Hydrosweep DS3。声速剖面（Sound Velocity Profiles, SVPs）数据取自本航次船上其他工作组的CTD测量数据。声速剖面数据通过HydrOffice SoundSpeedManager软件（https://www.hydroffice.org/soundspeed/main）进行预处理，并依托世界海洋图集2013（World Ocean Atlas 13，https://doi.org/10.7289/v5f769gt）进行数据扩展。声速剖面数据已于数据采集阶段投入应用。本次公开的多波束数据为未经过校正处理的原始数据，可能存在异常值与粗差，若未开展进一步编辑校正工作，不得用于栅格计算与海图绘制相关项目。原始多波束声呐数据以Teledyne/Atlas专用多波束处理格式（.asd）存储，并通过Teledyne/Atlas Parastore软件完成记录。原始数据文件可通过CARIS HIPS/SIPS等专业软件包进行后期处理。如需获取最新的船载配置文件，请查阅相关补充说明。
