Mooring line deployed in the Espartel Sill located in the Strait of Gibraltar consisting of an uplooking Acoustic Doppler Current Profiler (ADCP) (Teledyne RD Instruments, Inc.), a currentmeter Nortek Aquadopp (Nortek AS), a CT (Conductivity Temperature) SBE 37 probe (Sea-Bird Electronics, Inc.), and SAMI-pH and SAMI-CO2 Submersible Autonomous Moored Instruments (Sunburst Sensors, LLC.). CT, SAMI-pH and SAMI-CO2 were placed around 13 m above the sea bottom (360 m depth). The main objective is to monitor the Mediterrranean Outflow Water carbon parameters variability before it leaves the Mediterranean Basin to the Atlantic Ocean through the Strait of Gibraltar.

Apataki Atoll has been instrumented over a period of 3 months (from April 2022 to late July 2022) separated into 2 Legs. Physical process such as water level, currents ciruclation, water exchanges into passes and "hoa" and water column stratification have been measured to characterized the hydrodynamic functioning of this semi-opened pearl farming atoll. Numerous moorings have been deployed into lagoon, passes, hoa and external reef slope stations with common autonomous oceanographic instruments measuring at high sampling frequency. During the sampling period, one major meteorological event occurred, a distant mega swell hit the South-West Islands of French Polynesia including Apataki on 14th July and has significantly impacted its hydrodynamic.

Takaroa Atoll has been instrumented for a short period of 3 months (from July 2022 to October 2022) in order to get additionnal data into Takaroa passage (Teauoae Pass). One ADCP has been deployed to measure current direction and speed over the water column to evaluate the water exchanges between the lagoon and the ocean of this semi-open pearl farming atoll.

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.

RESOLAG is a sensor network located in French Polynesia, in the middle of the South Pacific Ocean. The program started in 2018 to acquire data on seawater parameter inside lagoon impacted by pearl oyster farming activity. It is a long-term monitoring of seawater temperature, disolve oxygen, turbidity, fluorescence and salinity. One of the network’s major goal is to better understand the link between black-pearl oysters and their environment, in order to improve management of the farming activity. RESOLAG was created by the Department for Marine Ressources Management of French Polynesia. It is a public organisation run by the gouvernment of French Polynesia. Therefore all data from the network are publicly available to download (under CC-BY licence).

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.

In 2019, the Ligurian DLTM Consortium (CNR, DLTM, ENEA, IIM, INGV) has installed a coastal cabled, real-time, monitoring station, at around 10 m depth in the Eastern Ligurian Sea (44°4’54.96”N 09°52’50.12”E in S. Teresa Bay, La Spezia). The coastal station monitors temperature, pressure, water conductivity and derived salinity at 10 m depth with very high frequency (10 minutes interval). The observatory has as main purpose the study of coastal ecosystems, hydrodynamic processes and, in the long term, the effects of climate change. It is also a test site for new instruments and sensors. Due to maintenance activities some records are missing. The two-year dataset proposed here will be upgraded annually.
