title: Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV SONNE during cruise SO308/2

description: Raw multibeam bathymetry data were collected aboard RV SONNE during cruise SO308/2 (PlanOz‐T) using a 12kHz Kongsberg EM 122 multibeam echosounder with 2x2 beam width. The expedition took place during 2024-12-26 – 2025-01-13 from Fremantle (Australia) to Wellington (New Zealand) in the Great Australian Bight and the Tasman Sea. Objectives of the Research & Training Cruise for the Universities of Bremen and Hamburg on SONNE expedition SO308/2 were to study:- Regional patterns of phyto-, micro- and mesozooplankton biomass, biodiversity & species composition and micronekton fauna- Relationship between zooplankton biodiversity and ecological productivity of the ocean region- Functional biodiversity: Role of different functional traits within zooplankton communities- Trophic interactions & marine foodweb structure: Establish trophic positions, predator-prey interactions, dietary spectra based on biomarkers (SI, FA)- Trace energy and carbon fluxes along marine food chains- Ecosystem functioning & biological carbon pump: Impact of zooplankton composition on biological carbon pump.- Training of students in state-of-the-art field-work methods in an international atmosphere.Data were recorded in the EEZ of Australia as well as outside EEZs. Sound velocity profiles (SVP) were applied on the data for calibration. 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 University of Bremen and Hamburg, provision of the data is supported by the DAM Underway Project and published according to the FAIR principles.

title: ADCP current measurements (38 kHz) during RV MARIA S. MERIAN cruise MSM108

description: Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM108 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 2.81 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.Data post-processing included water track calibration of the misalignment angle (0.38° +/- 0.6278°) and scale factor (0.9954 +/- 0.0083) 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; 0.3.

title: Continuous thermosalinograph oceanography along RV SONNE cruise track SO284

description: Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems, called self-cleaning monitoring boxes (SMBs). Usually the active (measuring) and passive (cleaning) systems are swapped every 12 hours. While temperature is taken at the water inlet in about 4 m depth, salinity is derived from conductivity and interior temperature within the SMB. Salinity was calibrated for each box independently against discrete water samples (see additional attachment). Temperature calibration was performed against CTD data. For details to all processing steps see Data Processing Report.

title: Continuous thermosalinograph oceanography along RV MARIA S. MERIAN cruise track MSM89

description: Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems.Usually the active (measuring) and passive (cleaning) systems are swapped every 6 hours. During the cruise the interval was changed to 12 hours. While temperature is taken at the water inlet in about 6.5 m depth, salinity is derived from conductivity and interior temperature within the interior measurement container. Salinity was calibrated independently for both measurement containers (MCs) with direct samples. Temperature was calibrated against CTD data. Except one, all CTD casts were conducted during active periods of MC1. Therefore only the temperature for MC1 was calibrated. For details to all processing steps see Data Processing Report.

title: ADCP current measurements (75 kHz) during RV SONNE cruise SO290

description: Upper-ocean velocities along the cruise track of Sonne cruise SO290 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 1.44 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.Data post-processing included water track calibration of the misalignment angle (-0.12° +/- 0.5821°) and scale factor (1.0004 +/- 0.0099) 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; 0.3.

title: Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV METEOR during cruise M126

description: Multibeam bathymetry raw data using the ship's own Kongsberg EM 122 multibeam echosounder was almost continuously recorded during RV METEOR cruise M126. Data was recorded on 28 days between 2016-04-20 and 2016-05-20. This dataset contains a survey in the Atlantic Ocean. The approximate average depth of the entire dataset is around 4200m.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.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: Shipboard ADCP current measurements (75 kHz) during RV METEOR cruise M208

description: Current velocities of the upper water column along the cruise track of R/V Meteor cruise M208 were collected by a vessel-mounted 75 kHz RDI Ocean Surveyor ADCP. The ADCP transducer was located at 5.0 m below the water line. The instrument was operated in three different configurations: 1) narrowband mode (WM10) with a bin size of 8.00 m, a blanking distance of 4.00 m, and a total of 100 bins, 2) broadband mode (WM1) with a bin size of 5.00 m, a blanking distance of 3.00 m, and a total of 125 bins, and 3) broadband mode (WM1) with a bin size of 5.00 m, a blanking distance of 3.00 m, and a total of 100 bins. The covered depth range was between 13.0 m and 809.0 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 2.1.1) was used for data post-processing. 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 (configuration 1: -46.3802° +/- 0.4543°, configuration 2: -46.4260° +/- 0.7293°, configuration 3: -46.4479° +/- 0.4118°) and scale factor (configuration 1: 1.0048 +/- 0.0085, configuration 2: 1.0048 +/- 0.0120, configuration 3: 1.0049 +/- 0.0071) of the measured velocities. The velocity data were averaged in time using an average interval of 60 s. Depth cells with ensemble-averaged percent-good values below 25% are marked as 'bad data'.
