This dataset contains turbidity (NTU) data acquired between August 2018 and June 2019 using a Wetlabs turbidimeter (ECO-BBRTD, serial # 215R) installed horizontally at 1.5 m height at the top of the SeaMoN East frame. The sensor was not calibrated as the sizes of the natural particles are unknown. Data was acquired every 15 minutes. The instrument is part of the SeaMoN East ecological monitoring node deployed at ca 10m away from the active hydrothermal edifice Tour Eiffel.

The Astan-Roscoff time-series data characterize the temperature and salinity of the Western English Channel. Between 1952 and 1982 the sampling station was located to the north-west of Batz Island. Since 1983, the sampling station is located at the current (https://www.somlit.fr/)-[https://www.somlit.fr]), accredited by the CNRS as a national Earth Science Observatory (Service National d’Observation: SNO), aiming at assessing their long-term evolution including both natural and anthropogenic forcings. Samples were collected with a Niskin bottle at high tide slack during neap tides at 2m-depth and at 60m-depth for the 1983-1999 period. Until 1970 the exact date of sampling is unknown, hence in the data set, the 1st of the month is present. Water samples where analysed for Salinity with a Salinometer Guidline Autocal and Temperature was measured during sampling with a reversing mercury thermometer (Richet and Wiese). Starting in 2000, this time series has been integrated in the SOMLIT ASTAN time-series, which is part of the( SOMLIT National Observation Service)-[https://www.somlit.fr/].

This dataset contains current data acquired between July 2017 and August 2018 using 3 TCM3 Ocean Bottom Tilt Current Meters installed next to the Tour Eiffel, Montségur and Crystal hydrothermal vent sites. The TCM-3 Ocean Bottom Tilt Current Meter from Lowell Instruments LLC (North Falmouth, MA, USA) measures current using the drag-tilt principle. The logger is buoyant and is anchored to the bottom via a short flexible tether. Drag from moving water tilts the logger in the direction of flow. The logger’s accelerometer and magnetometer channels are used to record the amount of tilt and direction of tilt (compass bearing). The array comprises 3 currentmeters, deployed near the Tour Eiffel, Montségur and Crystal hydrothermal vent sites. It is not connected to an energy node. The currentmeter's internal clocks are set to UTC time before deployment. Clock drift after recovery is not implemented in data but added as metadata in Table_TCM3EMSO_Azores 2016-2018.

This dataset describes the dissolved cobalt and manganese distributions in the East China Sea. Other parameters such as salinity, water temperature, potential density, dissolved oxygen, and nutrient (nitrate, phosphate, and silicate) concentrations are also included. Seawater samples used for generating this dataset were obtained during the KS-15-6 cruise onboard R/V Shinsei Maru between July and August 2015 (Stn1 to Stn15), and during the KH-15-3 cruise onboard R/V Hakuho Maru in October 2015 (F1, D4, B8, and I1). Dissolved cobalt concentrations were determined using cathodic stripping voltammetry at the University of Tokyo and by using inductively coupled plasma - mass spectrometry (ICP-MS) at Kanazawa University, Japan. Meanwhile, dissolved manganese concentrations were determined using ICP-MS at both the University of Tokyo and Kanazawa University. All samples were irradiated with ultraviolet light before analysis.

This dataset contains measurements of dissolved nitrate, phosphate and silica during two deployments, each lasting several weeks each at the OBSEA observatory during 2022 and 2023. Three prototype lab on chip in situ chemical analysers developed at the National Oceanography Centre, UK, were deployed at the site during summer 2022 and summer 2023. The nitrate sensor uses the Griess colorimetric assay and a copperised cadmium column to measure dissolved nitrate (and nitrite). Each sample measurement was calibrated by measuring onboard calibration standards prepared in artificial seawater with a salinity of 35. A blank solution and a standard solution containing 10 µmol / L of potassium nitrate were measured immediately prior to each sample measurement. Nitrate data is available between 2022-06-16 and 2022-07-06. Sample measurements were made every 2 hours initially, but this was decreased to once every 4 hours from 2022-06-30. The phosphate sensor uses a colorimetric assay based on the Molybdenum Blue method. Each sample measurement was calibrated by measuring onboard calibration standards prepared in artificial seawater with a salinity of 35. A blank solution and two standard solutions containing 0.5 µmol / L and 2 µmol / L of potassium dihydrogen phosphate were measured immediately prior to each sample measurement. Phosphate data is available between 2022-06-16 and 2022-07-05, with a sampling frequency of every 2 hours (decreasing to every 4 hours from 2022-06-30), and between 2023-07-21 and 2023-09-12, with a sampling frequency of every 12 hours. The dissolved silica sensor uses a colorimetric assay also based on the Molybdenum Blue method. Each sample measurement was calibrated by measuring onboard calibration standards prepared in artificial seawater with a salinity of 35. A blank solution and two standard solutions containing 5 µmol / L and 15 µmol / L of sodium hexafluorosilicate were measured immediately prior to each sample measurement. Dissolved silica data is available between 2023-07-21 and 2023-08-12, with a sampling frequency of every 6 hours. Timestamps in the datafiles are in UTC and concentration units are µmol / L.

Two quality controlled datasets here archived were collected during the oceanographic cruise MEIO that held in October-November 2022 over the South Western Indian Ocean, onboard S.A. Agulhas II. The first dataset is composed of continuous vertical profiles of the 12 oceanographic stations. The profiles have a resolution of 1dbar. The parameters reported in this data set are: pressure (in dbar), in-situ temperature (in °C), practical salinity, dissolved oxygen concentration (in µmol/kg), fluorescence of calibrated chlorophyll-a fluorescence (in µg/L), nitrate concentration (in µmol/kg) and particle attenuation @660nm (in 1/m). The second dataset is composed of discrete samples collected during the 12 stations. The parameters are the sensors measurements of every samples, dissolved oxygen concentration measured by the Winkler method (in µmol/kg), practical salinity measured by Autosal, concentration of silicate (in µmol/kg), concentration of phosphate (in µmol/kg) , concentration of nitrite (in µmol/kg), concentration of nitrate (in µmol/kg), concentration of pigments (processed by HPLC). These datasets aim to contribute to the extension of the One-Argo programme in the southwestern area of the Indian Ocean through the deployment of a significant number of floats; and to collect reference measurements through a multi-instrumented CTD rosette, allowing in particular to calibrate the robots’ sensors, just before their deployment. The two datasets were collected in concomitancy with the deployment of 29 One-Argo floats (WMO numbers : 5906536, 6903149, 4902620, 6903088, 6903148, 6990505, 5906970, 7901013, 4902626, 6903150, 5906972, 6903031, 5906540, 5906969, 4902623, 6990503, 3902471, 5906539, 6990504, 1902572, 5906537, 4902628, 7901003, 3902472, 6903033, 5906538, 1902573, 6903084, 5906971).
