Multibeam bathymetry raw data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS145/1

Multibeam data were collected with RV Polarstern along the route of cruise PS145/1 and data acquisition was continuously monitored during the survey. Multibeam sonar system was Teledyne/Atlas Hydrosweep DS3. SVPs were retrieved from SV probe and CTD data, as well as synthetic profiles from World Ocean Atlas 18. SVPs were processed with HydrOffice SoundSpeedManager (https://www.hydroffice.org/soundspeed/main) and extended with World Ocean Atlas 18 (https://www.ncei.noaa.gov/archive/accession/NCEI-WOA18). 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 Reson multibeam processing format (.s7k) were recorded with Teledyne PDS 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）在PS145/1航次的既定航线中采集，勘测全程对数据采集过程实施了持续监控。本次勘测使用的多波束声呐系统为Teledyne/Atlas Hydrosweep DS3。
声速剖面（Sound Velocity Profiles, SVPs）数据可通过声速探头、CTD数据以及世界海洋图集2018（World Ocean Atlas 18, WOA18）生成的合成剖面获取。声速剖面数据通过HydrOffice SoundSpeedManager软件（https://www.hydroffice.org/soundspeed/main）进行处理，并结合世界海洋图集2018完成数据补充延伸，补充数据来源网址为https://www.ncei.noaa.gov/archive/accession/NCEI-WOA18。声速剖面数据在数据采集阶段即已投入应用。
本数据集包含的多波束原始数据未经预处理，可能存在异常值与粗差，未经进一步编辑修正，不得用于格网计算及海图绘制类项目。原始多波束声呐数据以Teledyne Reson多波束处理格式（.s7k）存储，并通过Teledyne PDS软件记录生成。原始数据文件可通过CARIS HIPS/SIPS等专业软件包完成处理。如需获取更新后的船载配置文件，请查阅更多相关细节。
