title: Multibeam bathymetry raw data (Kongsberg EM710 entire dataset) of RV METEOR during cruise M122

description: Multibeam bathymetry raw data using the ship's own Kongsberg EM 710 multibeam echosounder was almost continuously recorded during RV METEOR cruise M122. Data was recorded on 25 days between 2015-12-30 and 2016-01-23. This dataset contains a survey towards the coast of Namibia & Angola. The approximate average depth of the entire dataset is around 400m.The data are archived at the Federal Maritime and Hydrographic Agency of Germany (Bundesamt fÃür 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 acquisition has been monitored at all times during surveying.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).

description: Multibeam bathymetry raw data using the ship's own Kongsberg (Simrad) EM 120 multibeam echosounder was continuously recorded during RV SONNE cruise SO184/2. Data was recorded on 20 days between 2005-08-01 and 2005-08-20. This dataset contains an elongated transit survey east of Sumatra and Suva, Indonesia. Data covers parts of the continental shelf and continental slope. The approximate average depth of the entire dataset is around 2300m.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.

title: Continuous thermosalinograph oceanography along RV METEOR cruise track M200

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 correction against independent data was performed for temperature and salinity. Finally, TSG1 was chosen for publication. For details to all processing steps see Data Processing Report.

title: ADCP current measurements (75 kHz) during RV SONNE cruise SO286

description: Upper-ocean velocities along the cruise track of Sonne cruise SO286 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 1.41 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 (-0.16° +/- 0.5311°) and scale factor (0.9985 +/- 0.0084) of the Ocean Surveyor signal. The average interval was set to 60 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: Shipboard ADCP current measurements (75 kHz) during Maria S. Merian cruise MSM129/2

description: Current velocities of the upper water column along the cruise track of R/V Maria S. Merian cruise MSM129/2 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 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 (-47.3103° +/- 0.5730°) and scale factor (0.9975 +/- 0.0087) 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 4 are flagged as 'potentially correctable bad data' because of velocities biases most likely caused by transducer ringing.

title: Continuous optical chlorophyll-a and turbidity data along R/V SONNE cruise SO296/1

description: Underway optical chlorophyll-a and turbidity data were collected along the cruise track with Sea-Bird Scientific ECO FLNTU sensors installed within two autonomous measurement systems, called self-cleaning monitoring boxes (SMBs). The SMBs measure alternatingly. While one box is measuring, the other one is being cleaned. The boxes switched generally every 24 hours. The water inlet for the SMBs is at about 4 m below sea surface. Observed chlorophyll-a and turbidity data were both quality controlled and a comparison for chlorophyll-a with satellite data using the GlobColour CHL1 product is additionally provided. Agreement between SMB chlorophyll-a and satellite chlorophyll-a is good. Linear regression yields a slope of 1.17 and an intercept of 0.05 µg/L. Pearson correlation coefficient is 0.73. Note that the instruments are factory-calibrated, however, no post-calibration was performed due to missing reference data. Details on all quality control steps and the comparison with satellite data can be found in the data processing report. The resulting data set contains the original data and corresponding quality flags achieved by the quality control algorithm. The data source is given through the name of the active SMB. The data set contains data during transit time and station work. We recommend to use ship's speed to filter for only transit data.

title: Shipboard ADCP current measurements (38 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 38 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 16.00 m, a blanking distance of 16.00 m, and a total of 80 bins, covering the depth range between 38.0 m and 1302.0 m.
