Water column raw data (Kongsberg EM710 entire dataset) of RV METEOR during cruise M190

Raw water column data were collected aboard RV METEOR during cruise M190 using a Kongsberg EM 710 multibeam echosounder. The expedition took place during 2023-06-08 – 2023-07-08 from Las Palmas (Gran Canaria) to Algeciras (Spain) in the Central Atlantic Ocean. The main objective of M190 was highly coordinated sampling of fluids, rocks, and biota as part of the joint geo-bio interface studies in the Research Area 'Ocean Floor as a Reactor' of the proposed Cluster of Excellence The Ocean Floor – Earth's Uncharted Interface.Data were recorded Portuguese EEZ around the Azores. 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. Acquisition and provision of the data are part of the DAM Underway Project and published according to the FAIR principles.

本数据集的水柱原始数据由"流星号"科考船（RV METEOR）在M190航次期间，通过康士伯EM 710多波束回声测深仪（Kongsberg EM 710 multibeam echosounder）采集获得。本次科考航次于2023年6月8日至2023年7月8日开展，航行路线为从拉斯帕尔马斯（大加那利岛）驶往西班牙阿尔赫西拉斯，作业海域位于大西洋中部。M190航次的核心目标为开展多介质协同采样，涵盖流体、岩石与生物群落，作为拟建卓越研究集群"海底——地球未被探索的界面"下设"海底作为反应容器"研究领域中联合地质-生物界面研究的组成部分。数据采集区域位于亚速尔群岛周边的葡萄牙专属经济区（EEZ）。本数据集已通过声速剖面（Sound velocity profiles, SVP）完成校准处理。详细信息请参阅环境数据集与航次报告。本数据集为未加工原始数据，若未进行后续处理，可能存在错误的深度测量值（伪影）。请注意，若未采用合适的声速剖面，可能会产生折射误差。本数据的采集与提供隶属于DAM航次项目（DAM Underway Project），并遵循FAIR原则（FAIR principles）进行公开发布。
