Sea water CTD measurements at 90 m depth in Trondheim, Norway, with salinity and temperature. netcdf.

Deep water formed around the Antarctic continent drives the world ocean circulation. More than 50% of this deep water is formed within only about 10% of the Antarctic circumpolar band: the Weddell Sea. Subtle changes in the circulation of the Weddell Sea can lead to major changes in floating ice shelves, with critical implications for global sea-level, the production of deep water, and the global ocean overturning circulation. The Filchner Trough on the continental shelf in the southern Weddell Sea plays an important role for the water mass exchange between the cold water on the continental shelf and the warm water off the continental shelf: It serves as a conduit for relatively warm water to flow southward across the continental shelf toward the Filchner Ronne Ice shelf and for the dense, cold water produced underneath the ice shelf to flow northward off the continental shelf to feed Antarctic Bottom Water. Four moorings (P1, P2, P4, P5) were places within the inflow pathway of the warm water at the northern entrance to the Filchner Trough on the continental shelf, and one mooring (P6) was placed off the continental shelf over the deep ocean. The mooring time series cover the period from February 2017 to March 2021 and are used to investigate the processes controlling the on-shore transport of relatively warm water onto the shelf toward the ice shelf and the interaction of the warm water with the cold dense water. The moorings provide observations of the circulation on the continental shelf and the temperature variability on small (tidal) to large (seasonal, interannual) time scales.

The mooring was deployed on 15 September 2017 from Norwegian Research Vessel Lance at 80.6°N and 7.26°E (depth of 730 m) in the Yermak Pass over the Yermak Plateau north of Svalbard. It comprised 3 instruments: an upward-looking RDI 75kHz, a Long Ranger Acoustic Doppler Current Profiler (ADCP) at 340 m with 16 m vertical resolution (25 bins of 16 m each) and a 2-hour sampling time; a Seabird SBE37 measuring temperature, salinity and pressure at 348 m with 10-minute sampling time; and an Aquadopp current meter at 645 m with a 2-hour sampling time. The mooring was retrieved on the 19 July 2020 by Norwegian Icebreaker K.V. Svalbard. The present dataset features: The ADCP 50-hour high pass filtered velocities and  the Aquadopp 50-hour high pass filtered velocities.

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/].

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.

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.
