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 Auguest 2018 and June 2019 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 file Sensor Metadata.

This data set contains the CTD data collected by the Stazione Oceanografica of CNR (Italy) from RV URANIA during eight oceanographic campaigns (Table 1). These cruises were part of an intensive field program in the Sicily Channel and in the southern Tyrrhenian basin conducted within the MATER project, funded under FP4-MAS3 (Grant agreement ID: MAS3960051). Data have been used in several studies (see Related documents).

The probes were calibrated in temperature and conductivity at the SACLANT Center of La Spezia, before and after each cruise, and at sea in salinity, against water samples. Declared instrumental precisions were 0.002 °C for temperature and 0.005 for salinity (PSS-78). The data set is provided per cruise as ODV Spreadsheet files in TXT format, containing: Cruise name Station number Type of acquisition (here C for CTD) Date in mon/day/yr and Time in hh:mm:ss Coordinates in Longitude [degrees_east] and Latitude [degrees_north] Bottom depth [m] Depth, salt water [m] Temperature, IPTS-68 [degC] Temperature, ITS-90 [degC] Salinity, PSS-78 (Practical Salinity)   Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI.

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.

Socheongcho Ocean Research Station (Socheongcho ORS) opened in October 2014, and was built to help advance the understanding of the dynamics of the Yellow Sea, including its influence on Korea’s marine, terrestrial, and atmospheric environments, via the continuous and simultaneous multidisciplinary observation of local air and sea environments. Socheongcho ORS is located in the central Yellow Sea about 50 km off the western coast of the Korean Peninsula. Its steel-jacket framed tower-type platform was built near the submarine rock named “Socheongcho” by the Korea Institute of Ocean Science and Technology (KIOST). The Korea Hydrographic and Oceanographic Agency (KHOA) has operated this platform since January 1, 2016. Socheongcho ORS stands 42 m in height above the datum level (DL) and consists of a boat landing plus 7 decks (Bottom Deck, Intermediate Deck, Cellar Deck, Accommodation Deck, Main Deck, Roof Deck, and Heli Deck). Most of its meteorological instruments and sensors are installed on the Roof Deck, including two anemometers, two barometer, two air temperature sensors, and two relative humidity sensors. Ocean temperature and salinity have been relatively consistently measured at Socheongcho ORS. Aanderaa inductive-type conductivity-temperature (CT) sensors are installed at depths of 5.5 m throughout the entire year, operating at 1 min sampling intervals by KHOA. Residential facilities are on the Accommodation Deck and the electrical control room are on the Main Deck, while a seawater desalination system and a diesel generator system are installed on the Cellar Deck.
