Multibeam bathymetry raw data (Kongsberg EM 122 working area dataset) of RV SONNE during cruise SO276@en

Multibeam bathymetry raw data was recorded in the North Atlantic during cruise SO276 MerMet 17-6 that took place between 2020-06-22 and 2020-07-26. The data was collected using the ship's own Kongsberg EM 122. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data (zip file) and the cruise report for details. The bathymetric data acquisition was carried out within the IceAge project which aims to investigate the North Atlantic ecosystem. Working areas have been selected to offer a variability of environments (e.g., variability of water depth, and geological setting (shelf, mid-ocean ridge, deep basin)). The bathymetric data were used to plan ROV dives and sampling stations as well as background for habitat mapping studies.本数据集为2020年6月22日至2020年7月26日期间执行的SO276 MerMet 17-6航次中，于北大西洋海域记录的多波束测深（Multibeam Bathymetry）原始数据。该数据由科考船搭载的Kongsberg EM 122系统采集获取。数据处理阶段已通过声速剖面（Sound Velocity Profiles, SVP）完成校准。详细信息请参阅环境数据压缩包及本次航次报告。 本次测深数据采集工作隶属于IceAge项目，该项目旨在探究北大西洋生态系统。作业区域经过科学遴选，涵盖了丰富的环境类型，包括不同水深梯度与多样的地质背景（大陆架（shelf）、洋中脊（mid-ocean ridge）、深海盆地（deep basin））。本测深数据可用于规划遥控水下机器人（Remotely Operated Vehicle, ROV）下潜任务与采样站位，同时亦可作为生境制图研究的基础背景数据。
