title: Shipboard ADCP current measurements (75 kHz) during Maria S. Merian cruise MSM129/1

description: Current velocities of the upper water column along the cruise track of R/V Maria S. Merian cruise MSM129/1 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 broadband mode (WM1) 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. Attitude data from the ship's motion reference unit were used by the data acquisition software VmDAS internally to convert ADCP beam velocities to geographic coordinates. The Python toolbox OSADCP (version 2.0.0) was used for data post-processing. Single-ping data were screened for bottom signals and, where appropriate, a bottom mask was manually processed. Acoustic Interferences were identified based on outliers in the ADCP echo intensity data. Echo intensity data were cleaned accordingly and affected velocity cells were flagged to be removed prior ensemble-averaging. The ship's velocity was calculated from position fixes obtained by the Global Navigation Satellite System (GNSS), taking into account lever arms of ADCP transducer and GNSS antenna. Accuracy of the derived water 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 processing included water track calibration of the misalignment angle (-47.2247° +/- 0.3048°) and scale factor (0.9979 +/- 0.0055) of the measured velocities. The velocity data were averaged in time using an average interval of 120 s. Depth cells with ensemble-averaged percent-good values below 25% are marked as 'bad data'. Furthermore, the time series of cell 1 to 3 are flagged as 'potentially correctable bad data' because of velocities biases most likely caused by transducer ringing.

title: Continuous thermosalinograph oceanography along RV METEOR cruise track M161

description: Underway temperature and salinity data was collected along the cruise track with two autonomous thermosalinograph (TSG) systems, each consisting of a SBE21 TSG together with a SBE38 Thermometer. Both systems worked independent from each other throughout the cruise. While temperature is taken at the water inlet in about 5 m depth, salinity is estimated within the interior TSG from conductivity and interior temperature. No calibration for temperature and salinity was performed. For details to all processing steps see Data Processing Report.

title: Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV SONNE during cruise SO298

description: Raw multibeam bathymetry data were collected aboard RV SONNE during cruise SO298 using a Kongsberg EM 122 multibeam echosounder. The expedition took place during 14.04.2023 - 02.06.2023 from Guayaquil (Ecuador) – Townsville (Australia) in the central Pacific Ocean. The main scientific aim of SO298 is to establish the distributions of trace elements and their isotopes (TEIs), quantify their sources from the four major ocean boundaries (rivers, atmosphere, exchange with sediments, ocean crust), and determine their biogeochemical cycling and relationships to large scale ocean circulation along a cruise track in the Equatorial Pacific Ocean (EPO). Data were recorded within the EEZs of Ecuador, Kiribati, Jarvis Island, Howland Island and Baker Island as well as outside EEZs. 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: Multibeam bathymetry raw data (EM 120 echosounder entire dataset) of RV METEOR during cruise M70/1

description: Multibeam bathymetry raw data using the ship's own Kongsberg (Simrad) EM 120 multibeam echosounder was almost continuously recorded during RV METEOR cruise M70/1. Data were recorded on 23 days between 2006-09-24 and 2006-10-17. Data cover various areas in the Mediterranean Sea. The approximate average depth of the entire dataset is around 1900m. During data acquisition the Kongsberg EM 710 multibeam echosounder was occasionally running simultaneously during the survey.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. No ancillary sound velocity profiles (SVP) from the cruise are archived at the BSH, thus added to this dataset. However, data analysis of the raw data reveled that SVP has been changed on several occasions during the cruise.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 may contain incorrect depth measurements (artifacts) 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/, 2021).

title: Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV MARIA S. MERIAN during cruise MSM64

description: Multibeam bathymetry raw data using the ship's own Kongsberg EM 122 multibeam echosounder was not continuously recorded during RV MARIA S. MERIAN cruise MSM64. Data was recorded on 2 days between 2017-05-30 and 2017-05-31 to re-calibrate the system. This dataset contains a survey west of the coast of Ireland. The approximate average depth of the entire dataset is around 2900m. 43 additional sound velocity profiles derived were generated on board, however no multibeam echosounder data were acquired in the vicinity of these events.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. However, 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.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).

title: Multibeam bathymetry raw data (Kongsberg EM 712 entire dataset) of RV MARIA S. MERIAN during cruise MSM64

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 MSM64. Data was recorded on 2 days between 2017-05-30 and 2017-05-31 to perform a Sea Acceptance Test of the system. This dataset contains a survey west of the coast of Ireland. The approximate average depth of the entire dataset is around 2900m. 44 additional sound velocity profiles derived were generated on board, however no multibeam echosounder data were acquired in the vicinity of these events.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.

Note that refraction errors can be expected due to the lack of proper SVP. Overall, it appears that the data quality is partially good and partially bad since the gridded hillshade data showed relatively many fuzzy artifacts at the slant beams in the northern area of the survey, however the remaining survey in the southern area is mainly clear from artifacts.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).

title: ADCP current measurements (38 kHz) during RV SONNE cruise SO292/2

description: Upper-ocean velocities along the cruise track of Sonne cruise SO292/2 were continuously collected by a vessel-mounted Teledyne RD Instruments 38 kHz Ocean Surveyor ADCP. The transducer was located at 6.0 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 2.92 s. Beam velocities as recorded by the data acquistion software VmDas were transformed to ship coordinates and after merging with the navigation and attitude data from the ship's gyro and Global Positioning systems into earth coordinates. 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 (-0.22° +/- 1.2887°) and scale factor (1.0040 +/- 0.0299) of the Ocean Surveyor signal. The average interval was set to 120 s. Velocity quality flagging is based on following threshold criteria: abs(UC) or abs(VC) &gt; 1.5 m/s, rms(UC_z) or rms(VC_z) &gt; 0.5.

description: Upper-ocean velocities along the cruise track of Sonne cruise SO292/2 were continuously collected by a vessel-mounted Teledyne RD Instruments 75 kHz Ocean Surveyor ADCP. The transducer was located at 6.0 m below the water line. The instrument was operated in narrowband mode with 8 m bins and a blanking distance of 8.0 m, while 100 bins were recorded using a pulse of 1.46 s.
