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: (i) the ADCP 50-hour smoothed daily velocities, conservative temperature and pressure time series interpolated every 10 meters within the 20-330m layer, (ii) the Aquadopp 50-hour smoothed daily velocities and pressure time series at 645 m; and (iii) the SBE37 50-hour smoothed daily conservative temperature, absolute salinity and pressure time series at 348 m.

IAOOS14, IAOOS15 and IAOOS25 were deployed from the Korean Icebreaker R/V Araon during cruises in the northern Chukchi Sea. IAOOS14 and IAOOS15 were deployed 300 m apart on the same floe on 12 August 2015 in the Makarov Basin (80.8°N;173°E) and they drifted together remaining always less than 6 km apart. IAOOS25 was deployed on 15 August 2017 south-west Mendeleev Ridge (77.7°N;180°E) and drifted westward to the continental slope of the East Siberian Sea. IAOOS14 and IAOOS25 stopped transmitting on 9 October 2015 and 19 November 2017 respectively, likely due to the loss of their profilers while crossing relatively shallow bathymetry. IAOOS15 dataset ends in 15 October 2015. Ocean profilers were PROVOR SPI (from French manufacturer NKE) equipped with a Seabird SBE41 CTD (Conductivity, Temperature, Depth) and a dissolved oxygen (DO) Aandera 4330 optode. The profilers were set to perform two upward profiles a day from 800 m (IAOOS 14), 300 m (IAOOS 15) and 420 m (IAOOS 25), upward starting at approximately 6 am and 6 pm. The present dataset is composed of CTD-DO data from IAOOS 14 and 15, and CTD data from IAOOS 25 in the Makarov Basin, corrected from salinity errors and interpolated vertically every 0.5 m.

The two platforms IAOOS 23 and IAOOS 24 were deployed within 600 m from each other at the North Pole from the Russia-operated Barneo ice camp on April 12, 2017. They followed a meandering trajectory, reaching as far as 30°E in the Nansen Basin, before turning back to the western Fram Strait. On both IAOOS 23 and 24, the ocean profiler was a PROVOR SPI (from French manufacturer NKE) equipped with a Seabird SBE41 CTD (Conductivity, Temperature, Depth) and a dissolved oxygen (DO) Aandera 4330 optode. For the first time, the profiler on IAOOS 23 also carried biogeochemical sensors. It featured a bio-optics sensor suite and a submersible ultraviolet nitrate analyzer (SUNA, Satlantic-Seabird Inc.). The bio-optics sensor suite (called Pack Rem A) combines a three-optical-sensor instrument (ECO Triplet, WET Labs Inc.) and a multispectral radiometer (OCR-504, Satlantic Inc.). The present dataset is composed of CTD-DO data from IAOOS 23 and 24, corrected from the thermal lag and the sensor lag, despiked and interpolated vertically every 0.5 m. It also comprises nitrate concentrations from the SUNA and CDOM fluorescence from the WETLabs ECO sensor on IAOOS 23. Other biogeochemical data will be added to this dataset. The profilers were set to perform two upward profiles a day from 250 m (IAOOS 23) and 350 m (IAOOS 24) upward starting at approximately 6 am and 6 pm. They provided a unique 8-month long dataset, gathering a total of 793 profiles of the temperature, salinity and oxygen (upper 350m) and 427 profiles of CDOM and nitrates concentrations (upper 250m).  

As part of the EPIGRAM project, two moorings, Aspex 9 and 10, equipped with temperature, conductivity and pressure sensors (Seabird microcat 37SM), were deployed offshore Aquitaine for a period of 2 years (2009-2011). The probes were calibrated in metrology and provide salinity values derived from calculations based on Fofonoff and Millard (1983) [Fofonoff, P. and Millard, R.C. Jr UNESCO 1983. Algorithms for computation of fundamental properties of seawater. UNESCO Tech. Pap. in Mar. Sci., No. 44, 53 pp. Eqn.(31) p.39. http://unesdoc.UNESCO.org/images/0005/000598/059832eb.pdf]. Several oceanographic missions ASPEX1, 2, 3 and 4, were dedicated to deploying and recovering these instruments. The frame of the mooring (Figure B) is laid on the seafloor with sensors at 0.5 m above it. Aspex 9 and 10 moorings are located at the continental shelf (at 148 m water depth) and continental slope (at 472 m water depth), respectively (Fig. A). Aspex 9 mooring recorded data from 18.07.2009 at 23:40:00 to 01.07.2010 at 09:18:00 (with a measurement every 120 seconds) and from 04.09.2010 at 23:30:00 to 10.08.2011 at 06:57:00 (with a measurement every 180 seconds). Aspex 10 mooring recorded data from the 18.07.2009 at 21:40:00 to 22.07.2010 at 23:18:01 and from 05.09.2010 at 01:20:00 to 10.08.2011 at 04:58:00 (with a measurement every 120 seconds). This ASPEX dataset can be downloaded from here: a zip file containing one .txt file with indications of recording time, location and water depth of the two moorings and four data files (one .txt file per mooring and per recorded period) with for each measurement the year (YYYY), month (MM), day (DD), hour (hh), minute (mm) second (ss) and pressure (P), temperature (T), conductivity (C) and salinity (S) values. As part of the PAMELA project, 18 XBT (eXpendable BathyThermograph) probes (Sippican) were launched in 2013 (July to September) offshore Aquitaine Basin. Seawater temperature profiles were thus acquired through the water column from different locations at the shelf area (at 140 m water depth), the continental slope and the basin (at 1213 m water depth) (Fig. A). Some of these XBT profiles are accessible via the Coriolis platform (http://www.coriolis.eu.org/). The complete GAZCOGNE1-2 dataset can be downloaded from here: a zip file containing one .txt file with indications of time, location and water depth for the XBTs and 18 data files (one .txt file per XBT profile).

The EuroMapApp task of the AtlantOS project aims to integrate Europe’s existing and future bathymetric data sets from the Atlantic Ocean into a seamless whole and put these results into a widely accessible format allowing immediate visualization of the seafloor for the specialist and non-specialist user alike. The partner institutions are GEOMAR, Ifremer, NIOZ, and NERC-BODC.

Extreme percentiles (1%, 5%, 95%, 99%) of bottom temperature and salinity, as well as (95%, 99%) of bottom currents, were modeled using SYMPHONIE on a numerical domain covering 65 × 60 km at a resolution of 80 m. The 10-m bathymetry used inside the Lacaze-Duthiers Canyon was collected during the CALADU_2021 cruise (https://doi.org/10.17600/18001575). Statistics of extreme values were derived from hourly fields simulated between November 1, 2012, and April 15, 2014. This period includes two contrasting winters: the winter of 2012–2013, which was cold with dense water cascading, and the winter of 2013–2014, which was warm. This dataset was produced to assess the probable distribution of habitats (habitat suitability modeling) for cold-water corals in the Lacaze-Duthiers Canyon at different resolutions as part of the European H2020 project REDRESS (Restoration of Deep-Sea Habitats to Rebuild European Seas, https://redress-project.eu/, Grant Agreement No. 101135492). SYMPHONIE is a component of the national service SIROCCO (research infrastructure ILICO). This dataset is related to the article "Mapping and Conservation of Cold-Water Corals in the Lacaze-Duthiers Canyon for Transboundary Management", submitted to Mediterranean Marine Science by Fabri et al. in 2025.

The Surface Ocean CO₂ Atlas (SOCAT) is a synthesis activity for quality-controlled, surface ocean fCO₂ (fugacity of carbon dioxide) observations by the international marine carbon research community (>100 contributors). SOCAT data is publicly available, discoverable and citable. SOCAT enables quantification of the ocean carbon sink and ocean acidification and evaluation of ocean biogeochemical models. SOCAT represents a milestone in biogeochemical and climate research and in informing policy. SOCAT data are released in versions. Each succeeding version contains new data sets as well as updates of older ones. The first version of SOCAT was released in 2011, the second and third version followed biennially. Automation allowed annual public releases since version 4. The latest SOCAT version (version 5) has 21.5 million observations from 1957 to 2017 for the global oceans and coastal seas. SOCAT contains data from the VOS, OceanSites network and mooring, buoy data in general as well as calibrated sensor data.

The Western Mediterranean Sea is a natural laboratory to address questions about the formation and evolution of continental margins and the relationship between surface and deep processes. The evaporites deposited during the late Miocene’s Messinian Salinity Crisis (MSC) strongly impact its sedimentological and geomorphological evolution. Hereafter, we present a compilation of some of the main regional seismic stratigraphic markers throughout the Western Mediterranean Sea. We provide in xyz format (z in second twt) the original, not interpolated, points interpretation of the following horizons: i) Acoustic basement, ii) Base and Top of the MSC salt, also known as Mobile Unit (MU), iii) base Pliocene and iv) Seafloor. The available reflection seismic dataset, coming from a collaboration between French, Spanish, Algerian and Italian research institutes, covers most of the Western Mediterranean sub-basins with the exception of the Ligurian Basin. This compilation is currently the most comprehensive and updated available in literature and provides a useful contribution to the scientific community working in sedimentary, tectonics and geodynamics studies in the Western Mediterranean Sea.

The SeaExplorer glider Sea028 was deployed from the research vessel R/V Lance on the 24 July 2017 at 78.65°N, 9.70°E, on the western slope of Svalbard. The glider was recovered on 7 August 2017 at 79.99°N, 9.51°E. It performed six crossing of the western Svalbard slope. The glider was equipped with a GPCTD (Glider Payload Conductivity Temperature Depth from SeaBird), a dissolved oxygen sensor (Sea Bird SBE43F), and an optical sensor measuring Chlorophyll a (470/695 nm), Colored Dissolved Organic Matter (CDOM, 370/460 nm), and the total particle concentration or backscatter (backscattering at 700 nm) (EcoPuck from Wetlabs). The dataset is composed of the data corrected from the thermal lag and the sensor lag, despiked and interpolated every 1m. The profiles are separated. Please note that the oxygen data are not accurate for the second half of the time series (sensor bias).
