What is the The ocean-climate-biodiversity nexus and marine carbon dioxide removal (mCDR) Call?
Expected Outcomes
• New environmental, legal, socio-political and governance knowledge on Ocean Alkalinity Enhancement (OAE).
• Enhanced modelling, monitoring and simulation capabilities (including AI tools) for marine carbon dioxide removal, and refined Earth System Models (ESMs) via CDRMIP.
• Operational, standardized monitoring frameworks for quantifying mCDR effectiveness and durability across time scales.
• Evidence-based European and global decision-making on mCDR, sustained leadership in the ocean–climate–biodiversity science nexus, and significant contributions to global scientific assessments.
Scope Requirements
• Research must be grounded in the Guide to Best Practices in Ocean Alkalinity Enhancement Research and follow the precautionary principle.
• Multi- and trans-disciplinary consortia must include natural sciences, engineering, social sciences, humanities and gender expertise.
• Proposals must allocate a dedicated work package and resources for strong collaboration and synergies with EU and international initiatives (UN Decade of Ocean Science, Horizon Europe missions, ESA coordination on Earth System Science, Copernicus, EOSC, ESFRI infrastructures, INFRA-2022-EOSC-01-03, INFRA-2024-EOSC-01-01).
• Data collection must adhere to INSPIRE principles and be deposited in open-access repositories (Copernicus, EMODnet).
• SSH and gender analyses must examine desirability, benefits and disbenefits “for whom” and include comprehensive justice and intergenerational perspectives.
• International cooperation is mandatory, with formal linkages to key ocean observing initiatives (GOOS, OBIS, MBON, ICOS, GCOS) and digital twins (Destination Earth).
Special Conditions
• Proposals must meet all admissibility and eligibility criteria (Annexes A–C, B countries, international organisations).
• If satellite EO or positioning data are used, Copernicus and/or Galileo/EGNOS must be utilized.
• Field release experiments for OAE are out of scope; only small-scale controlled studies are permitted in line with CBD Decision X/33 and London Protocol LC45/LP18.
• At least one high-ranking proposal will be funded under each option, provided thresholds are met (Annex D).
• All in-situ data must follow INSPIRE and open-access rules.
• Proposals must include resources for coordination with ESA and link to EU Digital Twins and relevant infrastructure.
• Compliance with EU financial and legal requirements, detailed in the Work Programme General Annexes and Lump Sum Decision (7 July 2021).
