This dataset contains current data acquired between july 2019 and June 2021 using 6 TCM-3 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 6 TCM-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 the metadata file. Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.

This campaign was carried out on May 15, 2021 on the route between Puerto Juárez and the Arrowsmith Bank course or “Bajo del Este”, as the fishermen call it. The bank is located 40 km east of Punta Cancun at coordinates 21°05'00''N-86°28'00''W. The ship's captain Guillermo Antonio Carrillo Corzo alias the "Teacher", a pilot (Cap. Watermelon) and a sailor (El Chalán). The goal was carry out temperature and salinity measurements in the water column at each of the CTD stations. Direction: 10 stations with a separation of 4 km between each one were planned. Stations 1 to 6 were covered without difficulty; however, at station 7 the waves and the current increased their intensity considerably, so no progress was made to the following stations. the diagram salinity temperature profiles of each station (aligned West to East) The salinity is between 35 and 36 UPS and in turn from 28 °C to 25.5 °C. The depth ranges at the stations were from 1 to 57 m deep.

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.

Lewis Wave Power Ltd. (LWP) (a wholly owned subsidiary of Aquamarine Power Ltd.) was seeking to develop a wave energy demonstration array off the west coast of the Isle of Lewis. As a first stage of the Environmental Impact Assessment (EIA) for the project, LWP commissioned Royal Haskoning Ltd. to produce an Environmental Scoping Report (Lewis Wave Power Ltd., 2011) to facilitate the identification and assessment of the potential environmental impacts associated with the project. The survey reported on here formed this field-based benthic component. Its purpose was to provide site-specific benthic data to inform an assessment of impact of the proposed development. The key objectives were to: Determine the distribution and abundance of marine habitats and communities within the study areas; Determine the substrate type at all locations sampled and Identify habitats or species of conservation importance.

Since 2015, 12 representative sites of the Mahoran reefs have been equipped on the sub-surface with probes measuring the temperature every 10 minutes (every 1 hour since mid-2021). The data from these probes are collected every 2 months by the Operations Department of the Parc marin de Mayotte. The aim is to better understand seasonal variations and bleaching phenomena. A computer program developed by the PNMM makes it possible to analyse these data. Regularly, new probes are purchased (NKE) and calibration tests are carried out.
