Multibeam bathymetry processed data (Atlas Hydrosweep DS 2 echo sounder entire dataset) of RV POLARSTERN during cruise ANT-XXIII/5 (PS69), South Atlantic Ocean

Multibeam data were collected during RV Polarstern cruise ANT-XXIII/5 (2006-04-13 to 2006-06-12). Multibeam sonar system was Atlas Hydrographic Hydrosweep DS 2 multibeam echo sounder. Data are processed with Caris HIPS, including sound velocity correction with SV data from CTDs and World Ocean Atlas 18 (https://www.ncei.noaa.gov/archive/accession/NCEI-WOA18), tidal correction with TPXO9_atlas_v5 (https://www.tpxo.net/global/tpxo9-atlas), and manual cleaning. The soundings are combined in daily files, the format is XYZ ASCII ( ). Additional grids have been computed with depth dependent cell size to visualize the data. These grids are not meant for scientific analysis or navigation, but for overview purposes only.

多波束数据采集于极星号考察船（RV Polarstern）的ANT-XXIII/5航次期间（2006年4月13日至2006年6月12日）。所使用的多波束声呐系统为Atlas Hydrographic公司的Hydrosweep DS 2多波束回声测深仪。数据通过Caris HIPS软件进行处理，包括利用来自温盐深仪（CTD）的声速（SV）数据及世界海洋图集18（World Ocean Atlas 18，https://www.ncei.noaa.gov/archive/accession/NCEI-WOA18）进行声速校正、通过TPXO9_atlas_v5（https://www.tpxo.net/global/tpxo9-atlas）进行潮汐校正，以及人工清理。测深数据整合为每日文件，格式为XYZ ASCII（）。此外，还计算了具有深度相关单元格大小的网格以可视化数据。这些网格并非用于科学分析或导航，仅作概览用途。
