SOCIB Glider Missions - Canales Endurance Line - was initiated in 2011, with in kind collaboration of CSIC (IMEDEA), covering both the Mallorca and Ibiza channel in a semi-continuous operational mode and sampling physical and biogeochemical observations. The Ibiza channel is a well-established biodiversity hotspot and accordingly more intensive monitoring of the Ibiza channel is carried out to capture the mesoscale and submesoscale structures and their relation to the weekly to seasonal and annual/inter-annual variability. On the canales endurance line, ocean gliders making repeated dives from the surface to 1000 m interior of the ocean, repeating the cycle every ~5 hours, and traveling ~5 km in the horizontal during each dive. The canales endurance line is covering both the Mallorca and Ibiza channel in a semi-continuous operational mode. The glider missions typically last about 60 to 90 days, providing 6-10 sections of the Ibiza channel and 2 sections of the Mallorca channel. Since 2011 the Canales Endurance line has completed 108 glider missions, covered 53000 km over the ground, and has more than 97000 physical and biogeochemical profiles.

The Black Sea is a semi-enclosed basin with limited water exchange with the open basins and significant river discharges. These inflows are critical to the Black Sea's hydrology, nutrient availability, and ecosystem biogeochemistry. In the Black Sea, the interaction of atmospheric forcing, river discharges, and mesoscale dynamics contributes to the formation of distinct water masses. The northern part of the Black Sea has a shelf exposed to seasonal hypoxia and eutrophication. In contrast, the southern half is deep and stratified, with anoxic waters below 100 meters. These characteristics made the Black Sea an enormous meromictic sea. In the DOORS project (Developing Optimal and Open Research Support), a glider mission was conducted during the DOORS field campaign from May 6 to June 17, 2023, in the Romanian Exclusive Economic Zone. The mission covered 288 nautical miles and collected 863 physical and biogeochemical profiles down to a depth of 1000 meters. During the glider mission, we performed ten transects to the shelf and close to the Danube Cone. Each transect lasted around four days to complete, allowing us to better understand the temporal and spatial variability.

The project aims at assessing the importance of a new monitoring line across the Algerian Basin between Palma de Mallorca and the Algerian Coast. The Algerian Basin (AB) is located in the south of the Western Mediterranean Sea and is characterized by the presence of fairly fresh surface waters coming from the Atlantic (Atlantic Water- AW) and the more saline waters from the northwestern Mediterranean region interacting at different scales from basin-scale to mesoscale structures. The project aims at assessing the importance of a monitoring line across the AB between Palma de Mallorca and the Algerian coasts. ABACUS project will contribute to data collection in The Southern European Seas, one of the main EU maritime policy objectives, as outlined in the Marine Strategy Framework Directive through a multi-platform study of the mesoscale variability and main physical and biological characteristics of the AC system.

This data product contains Real-Time (RT) datasets from the two oceanographic campaigns of the FaSt-SWOT project (Fine-Scale ocean currents from integrated multi-platform experiments and numerical simulations: contribution to the new SWOT satellite mission), which were conducted in the Balearic Sea during spring 2023. The FaSt-SWOT experiments were designed to validate the first observations of the Surface Water and Ocean Topography (SWOT) satellite mission during its fast-sampling phase. The primary objective is to improve the characterization of oceanic fine scales (20-100 km), by integrating multi-platform in-situ observations, satellite observations, numerical models, and innovative computational techniques. The RT datasets integrate measurements from a unique set of in-situ platforms deployed during the two campaigns including data from two Slocum Gliders (owned and operated by SOCIB), data from a total of 40 surface drifters (20 HEREON and 20 CARTHE) and continuous observations from the SOCIB Research Vessel, including the thermosalinograph (sea surface temperature and salinity), weather station, CTD casts (to 500 m depth for FaSt-SWOT leg 1 and 700 m for FaSt-SWOT leg 2) and GPS positioning. All datasets have been standardized in netCDF format following the SOCIB convention and include the corresponding quality control procedures for each platform. This combined dataset aims to assess the actual capability of SWOT to map Sea Surface Height (SSH) variability across these fine-scale ranges in the Balearic Sea. Keywords: FaSt-SWOT, SWOT satellite mission, Balearic Sea, gliders, drifters, research vessel, essential ocean variables, multi-platform in-situ observations.

Through the long-term monitoring program called “Canales”, gliders operated by SOCIB have been deployed in the Ibiza Channel (western Mediterranean) along a semi-continuous endurance line. Since 2011, more than 70 glider missions have been successfully performed, collecting temperature and salinity profiles from the surface to 950 m depth, from which geostrophic velocities were derived. Following the methodology described in Juza et al. (2025), total and water mass geostrophic transports were then computed for each completed section. The water masses are: recent and modified Atlantic Waters (AWr and AWm, respectively), Western Intermediate Water (WIW), Levantine Intermediate Water (LIW) and Western Mediterranean Deep Water (WMDW). This dataset contains the monthly climatology of the northward (positive) and southward (negative) flows for the total, AWr, AWm, WIW, LIW and WMDW transports in the Ibiza Channel over the period 2011-2022.

Lagrangian experiment in the Ibiza channel during Autumn 2018, aiming to use the novel CARTHE GPS drifters (low-cost, compact, practical, eco-friendly and able too track currents centered 40 cm below the surface) to validate HF-Radar (new Antenna Pattern Measurement) and WMOP surface velocities, capture all representative spatio-temporal scales of surface circulation, study dispersion of surface particles, perform HFR data assimilation experiment with WMOP.

CTD collection

The Argo observing network is composed of profiling floats which collect information from the ocean surface to subsurface. These floats collect vertical profiles of ocean temperature and salinity, and some also measure biogeochemical ocean properties. These data provide information about the 4-dimensional ocean, helping to understand the oceans’ role in the Earth's climate system and to improve future climate change estimates. As part of the Euro-Argo ERIC (European Research Infrastructure Consortium), SOCIB has contributed to the program in the Western Mediterranean Sea since 2011. Each year, SOCIB deploys three floats to maintain a set of five floats, distributed across the sea with an average spacing of 2 degrees. This ensures continuous observation capability. This dataset compiles SOCIB's contribution to Euro-Argo ERIC since January 2011.

The aim of this experiment was to assess the operational HF radar surface current velocities in the Ibiza Channel in a Lagrangian framework, by comparing against surface drifter derived velocities"

A coastal sea level reconstruction based on tide gauge observations is developed and applied to the western basin of the Mediterranean sea, including sea level anomaly (SLA) and interpolation error along the entire coastline. The reconstructions are carried out in four frequency bands: periods longer than 10 years, periods between 1 and 10 years, periods between 1 month and 1 year, and periods between 1day and 1month. Total sea level at monthly and daily resolution, obtained by merging the different frequency bands, is also provided. The reconstructions are based on an optimal interpolation method in which the correlation between tide gauge data and all coastal points has been determined from the outputs of the numerical model managed by the Balearic Islands Coastal Observing and Forecasting System (SOCIB, https://www.socib.es). The reconstructions for frequencies lower than 1 month use monthly observations from the Permanent Service for Mean Sea Level (PSMSL, https://www.psmsl.org/) database and cover the period from 1884 to 2019. For the reconstruction of higher frequencies, hourly observations from the Global Extreme Sea Level Analysis (GESLA–2, https://www.gesla.org/) dataset are used, and cover from 1980 to 2015.

The data set consists of real-time continuous coastal ocean surface current maps in the Ibiza Channel (Western Mediterranean) averaged over a time interval of 1 hour around the cardinal hour, measured by the coastal High-Frequency Radars installed. Surface ocean velocities estimated by HF Radar are representative of the upper 0.9 meters of the ocean for a central frequency of 13.5 MHz. acknowledgement=Ministerio de ciencia e innovacion (http://www.ciencia.gob.es/portal/site/MICINN/).

Synthetic particles trajectories were initialized on the model grid, spaced 0.0038 degrees in latitude and 0.0048 degrees in longitude, yielding roughly 400-m resolution. The grid is 527 (longitude) x 462 (latitude) and roughly covers part of the Alboran Sea; 213934 of these locations have valid trajectories, while the rest are launch grid points on land. Particles were advected with a fourth order Runge-Kutta scheme with a 10-minute time step. The position vector was augmented with the strain tensor components. The underlying velocity field was taken from the surface layer of the 3-hourly archive of a 1-month free run of the Western Mediterranean Operational Forecasting System, an implementation of the Regional Ocean Modeling System (ROMS) maintained by SOCIB. For the computation, archived velocities were linearly interpolated. Positions and strain tensor components are stored hourly, along with flags indicating when synthetic particles have reached either the model coast or an open boundary cell in the model.

This dataset supports the publication “Conditions for Reliable Divergence Estimates from Drifter Triplets” by Huntley et al (2022). The dataset contains the modeled drifter trajectories and a list of the observed CALYPSO drifter trajectories used in the work to ascertain the usefulness of the results. The full set of CALYPSO drifters can be found at https://www.aoml.noaa.gov/phod/gdp/index.php.

CALYPSO (Coherent Lagrangian Pathways from the Surface Ocean to Interior) is an ONR Departmental Research Initiative that addresses the challenge of observing, understanding and predicting the three-dimensional pathways by which water from the surface ocean makes its way into the deeper ocean. Discovering the routes by which trace substances, phytoplankton, and dissolved gases like oxygen, are transported vertically, as they are also carried horizontally by oceanic currents, is the goal of this research. An innovative set of observational techniques are being used, along with process study models, predictive models, and data synthesis, to identify coherent pathways for vertical transport and to diagnose and predict the physical processes that underlie such subduction.
