Multibeam bathymetry raw data (Kongsberg EM712 entire dataset) of RV MARIA S. MERIAN during cruise MSM137

Raw multibeam bathymetry data were collected aboard RV MARIA S. MERIAN during cruise MSM137 using a Kongsberg EM 712 multibeam echosounder. The expedition took place during 2025-05-10 – 2025-06-13 from Reykjavik (Iceland) to Reykjavik (Iceland) in the North Atlantic. The aim of M137 was to apply enhanced geophysical methods in order to image and identify sills on a detailed scale. Magmatic intrusions are widespread all over the globe. Recently, the impact of sills and dikes onto sedimentary basins is discussed intensly, e.g. for contact-metamorphism and venting of methane. Even global climate anomalies were recently linked to regional sill emplacements and associated outbursts of methane into the atmosphere. Data were recorded within the Norwegian EEZ including Svalbard. 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 BGR and CAU, provision of the data is supported by the DAM Project Underway Research Data and published according to the FAIR principles.

本数据集的原始多波束测深数据由"玛丽亚·S·梅里安号"（RV MARIA S. MERIAN）科考船在MSM137航次中采集，搭载设备为康士伯（Kongsberg）EM 712多波束测深仪（multibeam echosounder）。本次航次执行于2025年5月10日至2025年6月13日，航行区域为北大西洋，往返航线从雷克雅未克（冰岛）出发并最终返回雷克雅未克（冰岛）。MSM137航次的核心目标为应用改进的地球物理方法，以高精度成像并识别岩床（sill）构造。岩浆侵入体在全球范围内广泛分布，近年来学界围绕岩床与岩脉（dike）对沉积盆地的影响展开了广泛讨论，涉及接触变质作用与甲烷逸出等多个方向。近期更有研究将全球气候异常与区域性岩床侵位及其引发的甲烷向大气排放事件建立了关联。本数据集的采集区域涵盖包含斯瓦尔巴群岛在内的挪威专属经济区（EEZ）。数据采集后采用声速剖面（Sound Velocity Profiles, SVP）进行校准。详细信息请参阅环境数据集与航次报告。本数据集为原始未处理数据，若未进行后续处理，可能存在错误的水深测量值（伪影，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BGR与CAU完成，数据集的提供得到了DAM航次研究数据项目（DAM Project Underway Research Data）的支持，本数据集按照FAIR原则进行发布。
