title: Physico-chemical conditions during a summer-autumn transition in the Ross Sea region

description: Here we present physico-chemical data collected during two research cruises conducted to and across the Ross Sea, Antarctica in the summer of 2018 (February-March) and 2019 (January-February). The dataset includes measurements of temperature, salinity, oxygen, par and transmissivity obtained with a Sea-Bird Electronics (SBE) 911plus CTD. The CTD sensor was configured with SBE 3plus, SBE 4, and SBE 43 dual sensors for the parameters above, in addition to a seapoint fluorescence sensor, and a photosynthetically active radiation (PAR) sensor (Biospherical Instruments QCP‐2300L‐HP). These data were used to provide oceanographic context to DNA metabarcoding analysis of 18S rRNA V4 region that was carried out on DNA samples collected in parallel to nutrient and chlorophyll-a samples. Fastq samples from DNA metabarcoding analysis and the associated metadata (including nutrients, Chlorophyll-a, and size-fractionated chlorophyll-a) were deposited to GenBank under project numbers PRJNA756172 (2018 cruise) and PRJNA974160 (2019 cruise). The study resulting from this analysis has been submitted to Limnology and Oceanography.

title: Physical oceanography during RV HEINCKE cruise HE594

description: Conductivity-temperature-depth profiles were measured using a Seabird SBE 911plus CTD during RV Heincke cruise HE594. 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). The processing report for this dataset is linked below.

title: Agulhas Ring CTD sampled during SAGA34.5S cruise at southeast Atlantic Ocean

description: The data were collected as part of the South Atlantic Gateway in the global conveyor belt (SAGA) project. The general objective of the SAGA project is to quantify and monitor the returning limb of the Atlantic Meridional Overturning Circulation in the South Atlantic Ocean, with special attention to the interior-ocean zonal flows linking the eastern and western South Atlantic basins. As part of the project, the SAGA-34.5S cruise was carried out from February 1st to March 15th, 2022, on board the R/V Sarmiento de Gamboa. For the study of an Agulhas Ring, 10 hydrographic stations of this cruise have been selected and divided into two transects: a zonal transect from stations 75 to 80, sampling the South Atlantic waters; and a meridional transect from stations 80 to 84, sampling the AR. At each station, vertical profiles have been obtained by a conductivity-temperature-depth (CTD) SBE911plus (this dataset). Water samples were also taken by 24 Niskin bottles for dissolved oxygen (µmol/ kg), pH (https://doi.pangaea.de/10.1594/PANGAEA.971796), and nitrates (µmol/ L) (https://doi.pangaea.de/10.1594/PANGAEA.972151). These data are complemented with near-surface salinity and temperature values obtained from a Thermosalinograph (TSG) (https://doi.pangaea.de/10.1594/PANGAEA.972164), as well as velocity profiles from the sea surface down to depths of ≈ 600-900 m collected from a shipboard acoustic Doppler current profiler (SADCP, of 75 and 150 kHz, respectively) (https://doi.pangaea.de/10.1594/PANGAEA.972173 and https://doi.pangaea.de/10.1594/PANGAEA.972891). The temporal coverage of the data is 3 days (March 4-6, 2022) and the spatial coverage includes 34-38ºS and 6ºW-6ºE (southeast Atlantic Ocean).

title: Physical oceanography and fluorescence measurements (CTD/Rosette) during the Professor Multanovskiy expedition Transarktika-2019 Leg 4/2 in 2019, Arctic Ocean

description: A standard Sea-Bird Electronics Inc SBE911+ CTD system with single temperature and conductivity sensors was used to measure temperature, conductivity and pressure at 73 stations during an expedition to the Laptev and East Siberian Seas in September-October 2019 aboard the research vessel Professor Multanovskiy. To measure chlorophyll content in the water, a pumped WETLabs WETStar fluorometer was connected to the SBE911+ system. Additionally, a Seabird 19plus V CTD with a pumped fluorescence sensor (WETStar) was mounted in the rosette frame to measure the fluorescence of dissolved organic matter (fDOM). Salinity and temperature data from the SBE 19plus V2 CTD are also part of the data set.We followed the manufacturer's recommendation to calculate salinity using Seabird processing software. Salinity is reported as practical salinity (PSU). Data were averaged at depth intervals of 1 m. Data are from the 2019 Transarktika Expedition (Leg 4/2 from Murmansk to Vladivostok), an initiative of the Russian Antarctic and Arctic Research Institute (AARI), carried out in collaboration with the Russian-German CATS project and funded by Minobrnauki (CATS RFMEFI61619X0108) and BMBF (CATS 03F0831B).

title: Dissolved trace metals cadmium (Cd), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), zinc (Zn) measured in samples from the Polarstern cruise PS94 to the Arctic Ocean from August to October 2015

description: During the Polarstern TransARC II cruise (PS94) expedition water samples were taken in the Arctic Ocean north of 71 °N, between 17 August and 14 October 2015. The cruise was part of the international GEOTRACES program. Samples for trace metal analysis were taken using 24 trace-metal clean polypropylene samplers of 24 L, each mounted on an all titanium frame with a SEABIRD 911 CTD system. In an ISO Class 6 clean room container the samples were immediately filtered over &lt; 0.2 µm Sartobran 300 cartridges and acidified. The dissolved trace metals cadmium (Cd), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), zinc (Zn) were analysed at the Netherlands Institute for Sea Research with a Thermo Finnigan High Resolution Inductively Coupled Plasma Mass Spectrometer (HR-ICP-MS) element 2 after pre-concentration and matrix removal. This study provides a baseline to assess future change, and additionally identifies processes driving bio-essential trace metal distributions.

title: Biogeochemical variables and optimum multiparameter analysis results from the tropical and subtropical Atlantic of the MAFIA cruise in 2015

description: This dataset contains the results of the fluorescent dissolved organic matter characterisation (FDOM) and water mass optimum multiparameter analysis 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 for biogeochemical analyses 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. Oxygen solubility was computed using the equation of Benson and Krause (1984). AOU (µmol/kg) was calculated by subtracting measured oxygen concentration from the oxygen solubility values at saturation, with respect to the atmosphere. Fluorescence measurements were performed with a Perkin-Elmer LS55 spectrofluorometer and FDOM was characterised by means of a Parallel Factor analysis. Integrated values were estimated by multiplying the discrete measurements by the distance, in meters, between samples. The contribution of each water mass to each sample was objectively quantified applying an optimum multiparameter analysis (excluding mixed layer samples, here &lt; 100 m). The aim of this dataset was to jointly characterise the FDOM and water mass distributions to infer the processes that shape the dissolved organic matter pool in the deep ocean (water mass mixing and history vs. local processes).

title: Chlorophyll a distribution and size structure across contrasting water masses of the southwest Pacific Ocean

description: Here we present physico-chemical and biological data collected during 12 research cruises conducted in SW Pacific waters east of Aotearoa New Zealand between 2009 and 2017. Nutrient and chla samples were collected mainly with Niskin bottles deployed with a Seabird 9plus CTD rosette. A small fraction of the data presented were sampled also from manually deployed Niskin bottles and the RV Tangaroa Underway Flow-Through System (TUFTS) system equipped with temperature, salinity and fluorescence sensors. The dataset includes measurements of temperature, salinity, oxygen and transmissivity obtained with a Seabird 9plus; inorganic nutrients (dissolved reactive phosphorus, dissolved reactive silica, nitrate + nitrite); total chlorophyll a (chla) filtered onto GFF filter, size fractionated chla (0.2, 2, 20 microns) obtained by sequential filtration of seawater through 20, 2 and 0.2 micron polycarbonate filters; and derived mixed-layer depth estimated following temperature and density criteria. The depth of the euphotic zone included was calculated from chla concentration following the approach described in Maritorena and Morel, 2001 (doi:10.1029/2000jc000319). These data were used to provide oceanographic context to DNA metabarcoding analysis of 18S rRNA V4 region that was carried out on DNA samples collected in parallel to nutrient and chla samples. The study resulting from this analysis has been submitted to Progress in Oceanography.
