| contents | Multibeam bathymetry raw data using the ship's own Kongsberg EM 122 multibeam echosounder was not continuously recorded during RV MARIA S. MERIAN cruise MSM129/1. Data was recorded on 8 days between 2024-05-29 and 2024-06-05. This dataset contains an elongated transit survey (strait line) in the North Atlantic Ocean. The approximate average depth of the entire dataset is around 2900m. The data cover seamounts (no parallel spaced survey lines), which were predicted in the database of Gevorgian et al. 2023. These seamounts were charted on purpose during MSM129/1 to test how a targeted measuring of those features can be realized using this database as navigational reference points. Data acquisition was not constantly monitored only throughout the day, however also no system failures were noted at night times. Almost the entire time the system was set to operate with an opening angle of 65 degrees in starboard and port direction. Artificial sound velocity profiles (SVP) have been used to calibrate the system using the World Ocean Atlas 09 retrieved through the SoundSpeedManager (SSM 2024.0.3). Each day a new profile was uploaded into the Kongsberg Seafloor Information System. These ancillary sound velocity profiles (SVP) files from the cruise are part of this dataset. In addition sound velocity profiles calculated from CTD cast during MSM129/1 are part of this dataset, however not imported into the acquisition software during data acquisition. Data are unprocessed and therefore contains incorrect depth measurements (artifacts) without further processing. Note that refraction errors can be still expected due to the lack of proper SVP. Overall, the data quality is rather good since the gridded hillshade data showed relatively few obstacles. This publication is conducted within the efforts of the German Marine Research Alliance in the core area 'Data management and Digitalization' (Deutsche Allianz Meeresforschung, DAM). Data can be processed e.g. with the open source software package MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, http://www.mbari.org/products/research-software/mb-system/, 2023). |
