title: Water column raw data (Kongsberg EM 122 entire dataset) of RV SONNE during cruise SO299

description: Raw water column data were collected aboard RV SONNE during cruise SO299 using a Kongsberg EM 122 multibeam echosounder. The expedition took place during 14.04.2023 - 02.06.2023 from Townsville (Australia) to Singapore in the central Pacific Ocean. The main scientific aim of SO299 DYNAMET were to identify the variation in the composition of primary melts and magmas in complex microplate mosaics associated with subduction reversals including the role of aqueous fluids from the slab, different degrees of mantle melting, crustal contamination and fractionation, the contribution of different melts to the evolution of metal-rich magmatic- hydrothermal fluids and the large-scale structural control on their rise through the crust. Data were recorded within the EEZs of Papua New Guinea 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 (Kongsberg EM 122 entire dataset) of RV SONNE during cruise SO299/2

description: Raw multibeam bathymetry data were collected aboard RV SONNE during cruise SO299/2 using a Kongsberg EM 122 multibeam echosounder. The expedition took place during 2023-08-15 – 2023-09-02 from Singapore to Port Louis (Mauritius) in the central Pacific Ocean. The main scientific focus was on Krakatau archipelago in the Sunda Strait between the Indonesian islands of Java and Sumatra. The volcanic complex was the source of at least two major tsunamis in historic times. Reflection seismic profiles, hydroacoustic data, and sediment cores were collected West, South, and East of the archipelago. Data were recorded within the EEZs of Papua New Guinea and Indonesia 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. Data acquisition was done by 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: Shipboard ADCP current measurements (75 kHz) during RV MARIA S. MERIAN cruise MSM126

description: Current velocities of the upper water column along the cruise track of R/V Maria S. Merian cruise MSM126 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. 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 (-47.3690° +/- 0.5189°) and scale factor (1.0042 +/- 0.0104) of the Ocean Surveyor signal. The velocity data were averaged in time using an average interval of 120 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 1.5 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 0.3 m/s are flagged as 'probably bad data'.

title: Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV METEOR during cruise M206

description: Raw multibeam bathymetry data were collected aboard RV METEOR during cruise M206 using a 12kHz Kongsberg EM 122 multibeam echosounder. The expedition took place during 2024-12-01 – 2024-12-30 from Fortaleza (Brazil) to Belem (Portugal) in the Central Atlantic. The major aims of M206 Amazon-GEOTRACES 2 and the related projects is to better constrain the dissolved organic matter (DOM) and trace element (and their isotopes) budgets and net fluxes from the Amazon River system and the large mangrove belt into the Atlantic Ocean. Data were recorded within the EEZs of Brazil and French Guiana 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.

title: Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV SONNE during cruise SO273

description: Multibeam bathymetry raw data using the ship's own Kongsberg EM 122 multibeam echosounder was almost continuously recorded during RV SONNE cruise SO273. Data was recorded on 28 days between 2020-03-07 and 2020-04-06. This dataset contains a survey in the Indian Ocean towards and in the area of the Southwest Indian Ridge and Eric Simpson Fracture Zone (north of the Prince Edward Islands). In addition, this dataset contains transit data in South East Atlantic Ocean. The approximate average depth of the entire dataset is around 4400m. 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 excellent 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/, 2023).

title: n-Alkane biomarker, carbon, nitrogen and d13C data from the Barrow Peninsula (northern Alaska) before and after a one-year long incubation experiment

description: We conducted a one-year long incubation experiment with sediment samples from the Barrow Peninsula (Utqiagvik, Alaska). In 2022 sediments were cored in two thermokarst lakes (East and West Twin Lake), one drained lake basin and an undisturbed upland. Additionally, sediment samples were taken from Elson Lagoon and a semi-open lagoon. On in total 20 chosen depths of all cores, n-alkane biomarker analyses were conducted. Parallelly, carbon, nitrogen and carbon isotopic analyses were carried out. Subsequently, ten lacustrine and terrestrial samples were incubated for one year under aerobic and dark conditions at 10°C. At the end of the experiment, the initial analyses were repeated. The biomarker and elemental analyses were conducted at the Permafrost Research Section (AWI Potsdam) and the isotope data has been generated in the ISOLAB Facility (AWI Potsdam).

title: Continuous thermosalinograph oceanography along RV MARIA S. MERIAN cruise track MSM133

description: Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems. Usually, the systems are changed after 6 hours. While temperature is taken at the water inlet in about 6.5 m depth, salinity is estimated within the interior measurement container from conductivity and interior temperature. Neither temperature nor salinity calibration was performed. For details to all processing steps see Data Processing Report.
