Swath sonar bathymetry during POLARSTERN cruise ARK-XXII/2 (PS70) with links to multibeam raw data files

Multibeam data were collected during R/V Polarstern cruise ARK-XXII/2 leading to the central Arctic Ocean. Multibeam sonar system was ATLAS HYDROSWEEP DS2. Data are unprocessed and may contain outliers and blunders. Because of an error in installation of the transducers, the data are affected by large systematic errors and must not be used for grid calculations and charting projects.本数据集的多波束数据采集自极星号（R/V Polarstern）科考船ARK-XXII/2航次，作业区域覆盖北冰洋中部。所用多波束声呐系统为ATLAS HYDROSWEEP DS2。本次采集的数据未经处理，可能包含异常值与粗差。由于换能器安装存在误差，该数据集受到较大系统误差影响，不得用于网格计算及海图绘制项目。
