The East Sea Real-time Ocean Buoy (ESROB) is a surface mooring that has been in operation off the mid-east coast of Korea since 1999. The ESROB is 9 km off the coast (37° 32.24’N; 129° 12.92’E) in a water depth of 130 m, and provides meteorological and oceanographic (physical and biogeochemical) data every 10 min from Conductivity-Temperature-Depth (CTD) and acoustic Doppler current profiler (ADCP) instruments. The data provided here were collected between 2016 and 2020 and follow the data collected by previous publications. The data were quality controlled and assured using typical data processing methods, and have been used to address temporal variations in currents and water properties, as well as wind-and tide-induced internal waves. The uploaded data files contain variables in a NetCDF format that were obtained during each deployment. 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.

Dataset contains bottom temperature data from both fixed and mobile gear types (e.g. traps, trawlers, scallopers, long-liners) in the Gulf of Maine and the South New England Bight. The time series begins in 2015 and runs in real-time until today. The water depths range from 1- 900 meters. The variability associated with tidal, wind, seasonal, and inter-annual processes can be depicted at nearly all sites in this multi-year time series. This data was collected as part of the Environmental Monitors on Lobster Traps (eMOLT) project - a non-profit collaboration of industry, science and academics devoted to the monitoring of the physical environment of the Gulf of Maine and the Southern New England Shelf.

Navigation, meteorological and underway system data from the R/V Atlantic Explorer acquired during the FIGURE-CARING 2022 Eurofleets+ cruise.

Pressure and temperature records from the proximity of the Rainbow hydrothermal site.  The record spans from 8th to 26th May 2022. Data were acquired with an RBR Duet pressure sensor lent by PNIO. The pressure sensors was deployed on a broad band OBS (BBOBS) from the INSU national OBS parc at IPGP. Datafiles includes the full raw data file, and a file with only the record at the seafloor, after removing the ascent and the descent of the instrument, attached to the BBOBS) The seafloor position of the OBSs is: 36.23544°N, 36.91036°W, 2505 m waterdepth (~2538 m average depth recorded in this record).

Real time sea surface temperature measurement at 10 meters depth below spring tide. The thermometer is located on a pier on the island Vestmannaeyjar. The real time measurement started in September 2022.

The French Atlantic coast hosts numerous macrotidal and turbid estuaries that flow into the Bay of Biscay that are natural corridors for migratory fishes. The two best known are those of the Gironde and the Loire. However, there are also a dozen estuaries set geographically among them, of a smaller scale. The physico-chemical quality of estuarine waters is a necessary support element for biological life and determines the distribution of species, on which many ecosystem services (e.g. professional or recreational fishing) depend. With rising temperatures and water levels, declining precipitation and population growth projected for the New Aquitaine region by 2030, the question of how the quality and ecological status of estuarine waters will evolve becomes increasingly critical. The MAGEST (Mesures Automatisées pour l’observation et la Gestion des ESTuaires nord aquitains) high-frequency monitoring of key physico-chemical parameters was first developed in the Gironde estuary in 2004 ; the Seudre and Charente estuaries were instrumented late 2020. First based on real-time automated systems, MAGEST is now equipped by autonomous multiparameter sensors. Depending of the stations, an optode is also deployed to secure dissolved oxygen measurement. By the end of 2020, MAGEST had 12 instrumented sites. Portets is a measuring station located in the upper Gironde estuary (Garonne subestuary, about 20 km upstream of the Bordeaux metropolis.

AdriFOOS - Fishery Observing System (FOS) program aimed at using Italian fishing vessels as Vessels Of Opportunity (VOOs) for the collection of scientifically useful datasets. The dataset includes depth/temperature profiles collected by the AdriFOOS fleet in the period July 2021. These data are collected under the H2020 NAUTILOS project (ct. 101000825 - www.nautilos-h2020.eu)

Galata platform real time data is one of the most important sources of multi-parameter operational information in the Black Sea which will serve for monitoring, verification and improvement of modeling results and forecasts as well as for collecting long time series of data needed for climatic research. It also provides useful real time information for marine industry and safety.

MedFever – An expanding network of 12 small observatories was established in the Tyrrhenian Sea in 2021 by MedSharks and ENEA, building on the experience of an observation point established in 2016 in the Gulf of Naples.  Very high frequency measurements (15 minutes) at some standard depths (5-15-35m; occasionally at 10-20-25-30-50-60m) were obtained by voluntary diving centers using calibrated HOBO sensors (after calibration accuracy is about ±0.1 °C) in 12 stations evenly covering the Tyrrhenian sea. Due to various technical problems, some records are missing. The dataset proposed here will be upgraded annually.
