ABACUS 2026

Algerian BAsin Circulation Unmanned Survey 2026

Funded by AQUARIUS Transnational Access Call 1

ABACUS 2026 aims to harness the capabilities of the SOCIB glider facility to enhance our understanding of oceanic processes in the Western Mediterranean and their impact on biodiversity through the continuous monitoring of physical, chemical and acoustic indicators.

Region of Operation: Algerian Basin, Mediterranean Sea
Research Infrastructure Used: SOCIB Glider Facility

“ABACUS 2026 aims to harness the capabilities of the SOCIB glider facility to enhance our understanding of oceanic processes in the Western Mediterranean and their impact on biodiversity chemical, through the continuous monitoring of physical, chemical, and acoustic indicators. This effort contributes to the goals of the European Mission: Restore our Ocean and Waters by 2030. The project also seeks to advance knowledge of mesoscale and sub-mesoscale ocean dynamics, essential for improving regional ocean modelling, by integrating glider-based observations with satellite altimetry and data from the SWOT mission.”

MAIN OBJECTIVES

The ABACUS 2026 project aims to address critical knowledge gaps, enhance monitoring capabilities, and increase awareness of the impacts of human activities and climate change on Mediterranean marine ecosystems, particularly in the Algerian Basin. This region features dynamic circulation patterns and mesoscale phenomena that influence the physical, chemical, and biological properties of the water column, impacting biodiversity and ecosystem health. Despite this, it remains underexplored due to the scarcity of high-resolution observational data. Since 2014, the ABACUS team has conducted glider-based surveys in the basin, improving our understanding of its dynamics. However, significant gaps remain, such as the impact of water properties variability on its ecosystems, the presence and typology of emerging pollutants, anthropogenic noise, and marine mammal activity.
To address these gaps, ABACUS 2026 will use the SOCIB Glider Facility in Mallorca and bring together an international and interdisciplinary team of scientists, early-career researchers, and PhD students.

The project will execute two surveys south of Mallorca during spring and summer 2026, collecting high resolution data from surface to 1,000 meters depth along the 320 SWOT satellite ground track. SOCIB gliders will be equipped with CTD, oxygen, fluorescence, turbidity, and integrating innovative methodologies, such as passive acoustic monitoring and passive samplers for emerging pollutants. The collected data will provide insights into water mass properties, mesoscale dynamics, biodiversity impacts, and pollutant distribution, while also serving as ground truth for satellite calibration, enhancing models, and advancing knowledge of contaminants like microplastics and pharmaceuticals. The project aligns with the European Mission Ocean 2030, contributing to pollution-free seas and sustainable ocean management. Results will be shared via scientific publications, conferences, and outreach activities, including citizen science programs.
