title: Water column raw data (Kongsberg EM 122 entire dataset) of RV MARIA S. MERIAN during cruise MSM125

description: Raw water column data were collected aboard RV MARIA S. MERIAN during cruise MSM125 using a Kongsberg EM 122 multibeam echosounder. The expedition took place during 30.01.2024 - 06.02.2024 from Algeciras (Spain) to Funchal (Portugal) in the Northern Atlantic. Data were recorded in the Moroccan and Portuguese EEZs and outside. MSM125 was a short cruise of only four working days to test deep-sea research devices developed at MARUM at the University of Bremen and the Max Planck Institute for Marine Microbiology, Bremen (MPIMM), as part of the Cluster of Excellence The Ocean Floor - Earth's Uncharted Interface in in-situ operation so that they can be used in future research expeditions. The multibeam data provided here include a scientifically used part within the work area (2024-01-30T12:20:31 to 2024-02-04T10:55:51) and a transit part after leaving the work area and heading with fast vessel speed (10 kn) to the end harbour Funchal at Madeira (2024-02-04T10:55:51 to 2024-02-06T02:34:52). 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 provision is part of the DAM Underway Project and according to the FAIR principles.

title: Water column raw data (Kongsberg EM710 entire dataset) of RV METEOR during cruise M197

description: Raw water column data were collected aboard RV METEOR during cruise M197 using a Kongsberg EM 710 multibeam echosounder. The expedition took place during 30.12.2023 - 06.02.2024 from Limassol (Republic of Cyprus) to Catania (Italy) in the Mediterranean. The overarching aim was to use the rapidly changing Eastern Mediterranean Sea (EMS) as a natural laboratory to gain mechanistic understanding of biogeochemical and ecosystem transitions of a future (sub-)tropical ocean affected by global warming and other anthropogenic pressures. The M197 cruise on RV Meteor has the following objectives: characterising nutrient biogeochemistry and phytoplankton nutrient limitation of seawaters in the Eastern Mediterranean Sea, (ii) documenting in detail the microbial communities that inhabit these waters from the surface ocean to sediments, (iii) assessing mechanistic connections between nutrient biogeochemistry, surface ocean productivity, deeper water metabolism, and shelf sediments in the cycling of carbon and major nutrients, (iv) using the sedimentary record to assess past environmental change in the EMS. Data were recorded within the EEZs of Greece and Cyprus. 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.

title: Shipboard ADCP current measurements (75 kHz working area dataset) during RV MARIA S MERIAN cruise MSM112/2

description: Current velocities of the upper water column along the cruise track of R/V Maria S. Merian cruise MSM112/2 were collected by a vessel-mounted 75 kHz RDI Ocean Surveyor ADCP. The ADCP transducer was located at 6.0 m below the water line. The instrument was operated in narrowband mode (WM10) with a bin size of 8.00 m, a blanking distance of 8.00 m, and a total of 100 bins, covering the depth range between 22.0 m and 814.0 m. Heading, pitch and roll data from the ship's motion reference unit and the navigation data from the Global Positioning systems were used by the data acquisition software VmDAS internally to convert ADCP velocities into earth coordinates. Single-ping data were screened for bottom signals and, where appropriate, a bottom mask was manually processed. The ship's velocity was calculated from position fixes obtained by the Global Positioning System (GPS). 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. Data post-processing included water track calibration of the misalignment angle (-47.4056° +/- 0.6284°) and scale factor (1.0037 +/- 0.0102) of the Ocean Surveyor signal. The velocity data were averaged in time using an average interval of 60 s. Velocity quality flagging is based on different threshold criteria: Depth cells with ensemble-averaged percent-good values below 25% are marked as 'bad data'. Depth cells with velocities above 2.0 m/s are flagged as 'bad data'. Depth cells with a root-mean-square deviation between the measured ensemble-average velocity and a cell-wise running-mean velocity above 0.5 m/s are flagged as 'probably bad data'.

title: Multibeam bathymetry raw data (Kongsberg EM 712 entire dataset) of RV MARIA S. MERIAN during cruise MSM97/2

description: Multibeam bathymetry raw data using the ship's own Kongsberg EM 712 multibeam echosounder was not continuously recorded during RV MARIA S. MERIAN cruise MSM97/2. Data were recorded on 5 days between 2020-12-12 and 2020-12-22 in the North Sea and acquisition almost continuously monitored during the survey. During data acquisition, sound velocity measurements using sound velocity profiles (SVP) from sound velocity probes was applied on the data for data calibration. Ancillary SVP raw data (.asvp files) and SVP from CTD-cast (.txt) are part of this dataset publication.Data are unprocessed and therefore may contain incorrect depth measurements without further processing. 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/, 2017).During data acquisition the Acoustic Doppler Current Profiler (38 and 75 kHz) was occasionally switch on. When switched on, the centre of the beam showed erroneous measurements within regular intervals. However, this did not significantly lead to data quality loss in general. East of the survey area, data were recording during simultaneous operation of the Atlas Parasound P70 system. This led to complete false measurement data. However, these data are also part of this publication and marked in the parameter table.

title: Multibeam bathymetry raw data (EM 1002 echosounder entire dataset) of RV MARIA S. MERIAN during cruise MSM30

description: Multibeam bathymetry raw data using the ship's own Kongsberg (Simrad) EM 1002 multibeam_echosounder was not continuously recorded during RV MARIA S. MERIAN cruise MSM30. Data was recorded on 16 days between 2013-07-21 and 2013-08-13. This dataset contains a survey in the North Atlantic Ocean south of Svalbard. The approximate average depth of the entire dataset is around 300m. The data are archived at the Federal Maritime and Hydrographic Agency of Germany (Bundesamt für Seeschifffahrt und Hydrographie, BSH) and provided to PANGAEA database for data curation and publication. Ancillary sound velocity profiles (SVP) files from the cruise are archived at the BSH, thus SVP files are added to this dataset. Also data analysis of the multibeam raw data revealed that SVP has been changed during the survey.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 are unprocessed and therefore contains incorrect depth measurements (artifacts) without further processing. Note that refraction errors can be expected due to the lack of proper SVP. Overall, it appears that the data quality is rather good since the gridded hillshade data showed relatively few obstacles. The gridded data show many elongated structures on the seafloor. The ocean surface is covered with iceberg scours.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/, 2022).
