title: Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV SONNE during cruise SO305/2

description: Raw multibeam bathymetry data were collected aboard RV SONNE during cruise SO305/2 (E‐POLIO‐T M2Argo‐T) using a 12kHz Kongsberg EM 122 multibeam echosounder. The expedition took place during 2024-07-16 - 2024-08-05 from Singapore (Singapore) to Port Louis (Mauritius) in the Indian Ocean. The aim of SO305/2 EPOLIO was to determine the basin wide distribution of micropollutants and first evaluation of basin wide pollution state of the surface waters and water masses in the Indian Ocean. The aim of SO305/2 M2Argo-T was to obtain high-resolution seafloor Mapping and Magnetic field characterisation of the Argo transform fault at the Central Indian Ridge.Data were recorded in the EEZ of Mauritius and outside. 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 acquisition was done by Leibniz Institute for Baltic Sea Research, Warnemünde and GEOMAR Helmholtz Centre for Ocean Research, provision of the data is supported by the DAM Underway Project and published according to the FAIR principles.

title: Continuous thermosalinograph oceanography along RV HEINCKE cruise track HE616

description: Raw data acquired by a thermosalinograph (SBE21, SeaBird GmbH) on board RV HEINCKE were processed to receive a calibrated and validated data set of seawater temperature and salinity. Data were downloaded from DAVIS SHIP data base (https://dship.awi.de) with a resolution of 1 sec. The SBE21 was equipped with an additional external temperature sensor (SBE38, Sea-Bird GmbH). Raw data are converted to temperature and conductivity values using the calibration coefficients from the calibration before deployment. However, data can only be finally processed after replacement and renewed calibration because correction values for the sensor drift can only be obtained by the post cruise calibration. The thermosalinograph on board RV HEINCKE is exchanged about once a year and calibration procedures are conducted after every exchange. Salinity was calculated according to the instructions from the Practical Salinity Scale PSS-78 using the obtained internal temperature and conductivity data. Processed data are provided as 1min means of salinity and seawater temperature aligned with position data taken from master track of the respective cruise. Quality flags are appended according to the SeaDataNet Data Quality Control Procedures (version from May 2010).

title: Continuous optical chlorophyll-a and turbidity data along R/V SONNE cruise SO300/1

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 6 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. Analysis of the chlorophyll-a data during parallel operation of the sensors in the two boxes showed a significant offset between the sensors. The sensors were aligned resulting in a consistent chlorophyll-a time series. A comparison for the corrected chlorophyll-a with satellite data using the GlobColour CHL1 product is additionally provided. The Pearson correlation coefficient is low due to the overall small parameter range. Most data points lie at the 1:1 line within their measurement uncertainty. Details on all quality control steps and the comparison with satellite data can be found in the data processing report. Note that the instruments are factory-calibrated, however, no post-calibration was performed due to missing reference data. The resulting data set contains the original data and corresponding quality flags achieved by the quality control algorithm, and, in case of chlorophyll-a, also the corrected data with corresponding quality flag. 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: Continuous optical chlorophyll-a and turbidity data along R/V SONNE cruise SO299/2

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 6 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. Analysis of the chlorophyll-a data during parallel operation of the sensors in the two boxes showed a significant offset between the sensors. The sensors were aligned resulting in a consistent chlorophyll-a time series. A comparison for the corrected chlorophyll-a with satellite data using the GlobColour CHL1 showed significantly higher SMB Chla compared to satellite Chla. Satellite matchups during night-time and unaffected by non-photochemical quenching (20:00-24:00 local time) were used to calibrate the time series. We note that a calibration with satellite data is not as accurate due to temporal and spatial mismatch between the underway and satellite data and due to uncertainty of the satellite product. The chlorophyll-a time series shows effects of non-photochemical quenching which was not corrected (out of the scope of the quality control). The user may only want to use night-time data unaffected by non-photochemical quenching. Details on all quality control steps and the comparison and calibration 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, and, in case of chlorophyll-a, also the calibrated data with corresponding quality flag. 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.

Observed chlorophyll-a and turbidity data were both quality controlled. Analysis of the chlorophyll-a data during parallel operation of the sensors in the two boxes showed a significant offset between the sensors. The correlation between the two sensors during parallel operation time, however, is not very high due to the overall very narrow parameter range. Therefore, results from the sensor comparison for expedition SO300/1 were used to align the data resulting in a consistent chlorophyll-a time series.

title: Multibeam bathymetry raw data (Atlas Hydrosweep DS 2 echo sounder entire dataset) of RV METEOR during cruise M51/4

description: Multibeam bathymetry raw data using the ship's own Atlas Hydrographic Hydrosweep DS 2 multibeam echo sounder was not continuously recorded during RV METEOR cruise M51/4. Data was recorded on 11 days between 2001-12-13 and 2001-12-24. This dataset contains a survey in the Black Sea and in the Sea of Marmara, covering shallow and deep areas. 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) files from the cruise are archived at the BSH, thus no SVP files are added to this dataset. 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 moderate since the gridded hillshade data showed some obstacles (occasionally the swath width doubles in the Black Sea area). 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/, 2025).
