Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV METEOR during cruise M207@en

Raw multibeam bathymetry data were collected aboard RV METEOR during cruise M207 using a 12kHz Kongsberg EM 122 multibeam echosounder. The expedition took place during 2025-01-05 – 2025-02-11 from Belem (Brazil) to Mindelo (Cape Verde) in the Central Atlantic. The major aims of M207 are to investigate the variability of the western boundary current circulation off South America and to contribute to the assessment of the variability of the Atlantic Meridional Overturning Circulation (AMOC) at 11S. Data were recorded within the EEZ of Brazil as well as outside EEZs. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data and the cruise report for details. The data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors may occur when no proper SVP is applied. Data acquisition was done by GEOMAR Helmholtz Centre for Ocean Research, provision of the data is supported by the DAM Project Underway Research Data and published according to the FAIR principles.本数据集为M207航次期间，搭载于“流星号”科考船（RV METEOR）的12kHz康士伯（Kongsberg）EM 122型多波束测深仪所采集的原始多波束测深数据。本次科考航次的执行时段为2025年1月5日至2025年2月11日，航行区域覆盖中大西洋海域，航线从巴西贝伦出发，终至佛得角明德卢。M207航次的核心科学目标为：探究南美沿岸西边界流环流的变化特征，并为评估南纬11°处大西洋经向翻转环流（Atlantic Meridional Overturning Circulation，AMOC）的变化提供数据支撑。数据采集范围覆盖巴西专属经济区（Exclusive Economic Zone，EEZ）及其外海域，并已采用声速剖面（Sound Velocity Profiles，SVP）完成校准校正。详细信息请参阅环境数据集及本航次报告。本数据集为原始未处理数据，若未进行后续加工，可能包含错误的水深测量值（伪迹，artifacts）。请注意，若未采用合适的声速剖面进行校正，可能会出现折射误差。数据采集工作由德国亥姆霍兹海洋研究中心（GEOMAR Helmholtz Centre for Ocean Research）完成，数据提供工作得到DAM实时研究数据项目（DAM Project Underway Research Data）支持，且本数据集依据FAIR原则完成发布。
