    ADCP current measurements (38 kHz) during Maria S. Merian cruise MSM96 (2020)
    PANGAEA
    Details
    Publikationsdatum: 2024-01-26
    Beschreibung: Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM96 were continuously collected by a vessel-mounted Teledyne RD Instruments 38 kHz Ocean Surveyor ADCP. The transducer was located at 6.5 m below the water line. The instrument was operated in narrowband mode with 32 m bins and a blanking distance of 16.0 m, while 50 bins were recorded using a pulse of 2.87 s. The ship's velocity was calculated from position fixes obtained by the Global Positioning System (GPS). Heading, pitch and roll data from the ship's gyro platforms and the navigation data were used by the data acquisition software VmDas internally to convert ADCP velocities into earth coordinates. Accuracy of the ADCP velocities mainly depends on the quality of the position fixes and the ship's heading data. Further errors stem from a misalignment of the transducer with the ship's centerline. The average interval was set to 60 s. Data post-processing included water track calibration of the misalignment angle (0.44° +/- 0.8536°) and scale factor (1.0015 +/- 0.0180) of the Ocean Surveyor signal.

    Publikationsdatum: 2024-01-26
    Beschreibung: Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM96 were continuously collected by a vessel-mounted Teledyne RD Instruments 75 kHz Ocean Surveyor ADCP. The transducer was located at 6.5 m below the water line. The instrument was operated in narrowband mode with 8 m bins and a blanking distance of 4.0 m, while 100 bins were recorded using a pulse of 1.43 s. The ship's velocity was calculated from position fixes obtained by the Global Positioning System (GPS). Heading, pitch and roll data from the ship's gyro platforms and the navigation data were used by the data acquisition software VmDas internally to convert ADCP velocities into earth coordinates. Accuracy of the ADCP velocities mainly depends on the quality of the position fixes and the ship's heading data. Further errors stem from a misalignment of the transducer with the ship's centerline. The average interval was set to 60 s. Data post-processing included water track calibration of the misalignment angle (-47.18° +/- 0.7276°) and scale factor (1.0064 +/- 0.0121) of the Ocean Surveyor signal.

    Details
    Publikationsdatum: 2024-04-20
    Beschreibung: Multibeam bathymetry raw and processed data (RESON Seabat T50Extended Range) of Research Vessel Littorina at Fehmarn Belt in the western part of the Baltic Sea. The raw data (.db format) were processed using QPS Qimera software (v 1.7), based on the following workflow: 0.Raw data -〉 1.Apply correct Sound Velocity Profiles -〉 2. correct lever arm offsets -〉 3. Finalize with manual 2D and 3D point editing. The corrected soundings were used to create a GeoTIFF (EPSG Code:4326) .gsf data and GeoTIFF are provided. In addition software is provided with the aim of establishing a benchmark for terrain based navigation correction software using mutlibeam data. A) A script that allows to alter navigation solutions B) A script that allows to compare navigation solutions By altering the original and correct navigation and using the product as a basis for a terrain based navigation correction algorithm, the quality of such an algorithm can be measured by comparing its output to the original navigation. This in turn allows quantitative comparisons between different algorithms or settings. In addition to the original navigation some altered navigation files are provided (in .csv file format).

    Sediment echosounder raw data (Atlas Parasound P70 echosounder entire dataset) of RV MARIA S. MERIAN during cruise MSM96 (2021)
    PANGAEA
    Details
    Publikationsdatum: 2024-04-20
    Beschreibung: This dataset contains sediment profiling hydroacoustic data from RV MARIA S. MERIAN's Atlas PARASOUND P70 echosounder system. The data was recorded almost continuously during cruise MSM96 in the North-East Atlantic (2020-10-12 - 2020-11-09). This dataset contains the raw data files as created by the system along the cruise with Atlas PARASTORE software (.asd, .sgy, .ps3) and ancillary data. No data processing or quality control was conducted. The dataset additionally contains screenshots of selected parts of the recordings for visualization and data selection purposes. The PARASOUND data was recorded to complement the extensive multibeam data recordings of the cruise and to select sampling sites for the multicorer deployments. Data was recorded during multibeam stations and the vessel speed rarely reduced below 7 knots. Vessel speed varies throughout the dataset. This dataset does not contain any dedicated, slow-speed PARASOUND profiles. 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), MareHub (Helmholtz) & iAtlantic (EU) research projects.

    Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV MARIA S. MERIAN during cruise MSM96 (2021)
    PANGAEA
    Details
    Publikationsdatum: 2024-04-20
    Beschreibung: Raw multibeam bathymetry data was recorded in the North-East Atlantic during cruise MSM96 that took place between 2020-10-10 and 2020-11-10. The data was collected using the vessel-mounted Kongsberg EM122 multibeam echosounder. To enhance MBES data accuracy, one sound velocity profile (svp) cast was conducted in the vicinity of each working area prior to the MBES survey. The MBES acquisition was performed using the Kongsberg SIS Seafloor Information System software. This data was acquired in the context of the DAM (German Marine Research Alliance), MareHub (Helmholtz) & iAtlantic (EU) research projects.
