title: Physical oceanography during RV HEINCKE cruise HE641

description: Conductivity-temperature-depth profiles were measured using a Seabird SBE 911plus CTD during RV HEINCKE cruise HE641. The CTD was equipped with duplicate sensors for temperature (SBE3plus), conductivity (SBE4) and oxygen (SBE43). Additional sensors such as a WET Labs C-Star transmissometer, a WET Labs ECO-AFL fluorometer and an altimeter (PSA-916 Teledyne (Benthos)) were mounted to the CTD. Temperature, conductivity and oxygen sensors are calibrated by the manufacturer once a year before being mounted in January. They are used throughout the year and no post-cruise or in-situ calibration is applied. All other sensors are calibrated irregularly. Data were connected to the station book of the specific cruise as available in the DSHIP database. Processing of the data including removal of obvious outliers followed the procedures described in CTD Processing Logbook of RV HEINCKE (hdl:10013/epic.47427).

title: Noble gas data during SAS21 Oden cruise

description: This data set provides the final measurement results of noble gas samples taken during the Synoptic Arctic Survery 2021 in the central Arctic Ocean on the icebreaker Oden (Snoeijs-Leijonmalm et al., 2022). At six distinct stations, located in the Nansen Basin, above the Gakkel Ridge, in the Amundsen Basin, the Makarov Basin and north of the Greenland shelf, two replicate samples were taken at 11 depths covering the complete water column from the surface to the ocean floor as part of the project Ventilation and Anthropogenic Carbon in the Arctic Ocean. Samples were transferred from Niskin bottles to copper tubes under atmospheric isolation (Beyerle et al., 2000). At Heidelberg University, the samples were analyzed on a sector field mass spectrometer for the dissolved concentrations of helium, neon, argon, krypton and xenon, as well as the 3He/4He ratio, from summer 2022 until spring 2025 within several measurement runs (Schwenk et al., 2022). The obtained concentrations were converted into saturation anomalies (Jenkins et al., 2019), based on the prevailing temperature and salinity measured during the cruise for each data point respectively (Heuzé et al., 2022). If applicable, both replicate measurements are averaged and the final result is stated. These noble gas concentration and saturation data can be used to identify ocean surface processes like sea ice formation and melt, cooling of inflowing water masses or bubble intrusion caused by wind and breaking waves.

title: Physical oceanography during RV SONNE cruise SO306

description: Physical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV SONNE during research cruise SO306. The CTD system is comprised of a Seabird SBE911plus including dual respectively redundant sensor and pump packages. The SBE11plus Deck Unit remains on board in a laboratory and supplies on one hand power to the SBE9plus underwater unit, on the other hand data telemetry between the SBE9plus and a measurement PC. The SBE9plus underwater unit itself holds a pressure sensor and is interfacing with dual SBE3 temperature, SBE4 conductivity and SBE43 oxygen sensors, as well as two SBE5 pumps to provide a pumped water supply past each sensor. The system also carries an optical FLNTU sensor to measure a combination of back-scattering, turbidity, and chlorophyll-a. To quantify the photo-synthetically active radiation a PAR sensor is installed as well.

title: Physical Oceanography measured on bottle water samples during ODEN expedition SO21 for the Synoptic Arctic Survey

description: Discrete bottle values of Temperature, Salinity, Dissolved Oxygen, Chlorophyll A fluorescence and Coloured Dissolved Organic Matter (CDOM) collected in the Arctic Ocean, over the western Eurasian Basin and Lomonosov Ridge, between 2 August and 11 September 2021, from I/B Oden. This is the Swedish contribution to the international Synoptic Arctic Survey. This dataset merges the bottle data from the full-depth physical CTD and the shallow biological CTD. Both systems had the standard SeaBird SBE911 plus system with dual sensors to measure in-situ temperature and conductivity and single sensors measuring pressure and oxygen. The physical CTD also had a CDOM sensor (Turner Cyclops fluorometer), while the Chl-A fluorometer (WET Labs, ECO-AFL/FL) was moved throughout the expedition between the two systems. Salinity, Oxygen, Chl-A fluorescence and CDOM were calibrated against sample data collected and analysed by the co-authors: - Salinity samples from the deep stations were analysed post-cruise using a salinometer (Guildline Autosal) and IAPSO standard seawater at the GEOMAR, Germany. - Dissolved oxygen was determined onboard using an automatic Winkler titration setup with UV detection (Scripps Institute of Oceanography Oxygen Titration System version 2.35m). - Chl-A concentration was determined post-cruise from flow cytometry (FCM) at Linnaeus University, Sweden. The samples consisted of 4 mL cryovials, of which 3.8 mL was sample water and 76 μL 25% EM grade glutaraldehyde solution (Glu stock). The samples incubated at room temperature for 5 minutes before flash freezing in liquid nitrogen and then placing in the -80 °C freezer in cryoboxes. - CDOM was determined post-cruise at the National Institute of Aquatic Resources - DTU Aqua, Denmark, following the method of Lawaetz and Stedmon (2009) This dataset contains the bottle data of the casts where bottles were fired. For more information about each sensor and their calibration, the reader is invited to check the cruise report (final version submitted on 20 September; shareable version with DOI coming soon)

title: Glycerol dialkyl glycerol tetraethers (GDGT) lipids and CARD-FISH data from suspended particulate matter from the central Baltic Sea

description: During expedition EMB201 in the Baltic Sea we investigated the local producers of glycerol dialkyl glycerol tetraethers (GDGT) and their thriving depth by a combined 16S rRNA gene amplicon sequencing/ CARD-FISH and lipidomic approach. Water samples were taken in December 2018 by a pump-CTD, a giant water sampler and with Niskin bottles at the surface, suboxic and sulfidic zones of the Landsort Deep, Fårö Basin and East Gotland Basin. This data set contains the CARD-FISH and lipidomics data, while the 16S rRNA gene sequencing data is available on ENA. Cell abundance was analysed in an aliquot of 40 ml filtered (pore size 0.22 micro m) sea water fixed with particle-free formaldehyde. Archaeal cells on the filters were specifically hybridized via catalysed reporter deposition-fluorescence in situ hybridization (CARD-FISH) using the Cren537 probe. Cells on the hybridized filter were counter-stained with 40,6-diamidin-2-phenylindol (DAPI). For lipid analysis, 150–600 L sea water were filtered with a flow rate of 1.5 L min-1 on pre-ashed, 142-mm-diameter, 0.7µm pore size glass fibre GF/F filters, and frozen at –20 °C. The filters were lyophilized before different extraction methods were used to obtain intact and core GDGTs by ultra-sonification in different solvent mixtures. The combined supernatants were phase separated before analysis by high performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS2) for intact polar lipids and by high performance liquid chromatography coupled to atmospheric pressure chemical ionization mass spectrometry (HPLC APCI-MS; ThermoScientific) for core GDGTs.

title: Abundance, cell volume, biomass, viability and leucine incorporation rates of prokaryotes in the tropical and subtropical Atlantic

description: This dataset contains the results of the characterisation of the prokaryotic community by flow cytometry and tritiated leucine incorporation from the MAFIA cruise (Migrants and Active Flux In the Atlantic ocean). Samples were collected in the tropical and subtropical Atlantic during the MAFIA cruise (April 2015) on board the BIO Hespérides. Seawater samples were collected at 13 stations (from the Brazilian coast to the Canary Islands), from the surface down to 3500 m, using a General Oceanics oceanographic rosette equipped with 24 l PVC Niskin bottles. Abundance and cell characteristics (high nucleic acid content fraction, cell volume, viability) were based on measurements performed with a FACSCalibur (Becton-Dickinson) flow cytometer. Leucine incorporation rates were estimated with tritiated leucine (Kirchman et al. 1985) using centrifugation and filtration methods (Smith and Azam 1992). The aim of this dataset was to estimate the influence of surface productivity on the standing stock, characteristics and activity (as leucine incorporation) of prokaryotes across the water column.

title: In situ observational data of macro-nutrients off western Patagonia in Jan/Feb 2017

description: The dataset compiles in situ observational data obtained during the R/V Mirai MR16-09 cruise (2017-01-21 to 2017-02-03) off western Patagonia, Chile. In terms of chemical variables, the dataset includes information of nutrients, nutrient ratios, dissolved oxygen and ammonium concentrations. Water samples for nutrients analysis were collected in duplicate at discrete sampling depths (0, 10, 25, 50 and 100 m depth) from a 36-Niskin bottles (12-liter each) SBE carousel water sampler. The samples were taken into 10 mL polyacrylates vials which were rinsed three times before filling. The closed vials were put into a water bath, set at ambient temperature (22 ± 1°C), for about 30 minutes to stabilize the temperature of the samples, after which were analyzed in an auto-sampler tray within 24 hours after collection. Nitrate, phosphate, silicate and ammonium concentrations were determined using the QuAAtro 2-HR systems (BL-Tech), which the detection limits were 0.02 μmol kg⁻¹, 0.003 μmol kg⁻¹, 0.03 μmol kg⁻¹, and 0.02 μmol kg⁻¹, respectively.
