Global climate impacts of extreme brine input to the ocean

Objective

C-BRINES exploits a unique geological record of a massive gypsum precipitation event that occurred 5–6 million years ago in the Mediterranean, both to train 15 Doctoral Candidates (DCs) and to investigate gypsum’s potential as an innovative marine Carbon Dioxide Removal (mCDR) technology. Newly acquired deep sea sediment cores that capture gypsum-driven changes to ocean chemistry (alkalinity) also preserve evidence of its influence on ocean temperatures, marine ecology and the carbon cycle. C-BRINES will use these multi-proxy records to validate new physical and biogeochemical models designed to simulate this ancient alkalinity perturbation, providing the first natural experiment for evaluating gypsum-driven Ocean Alkalinity Enhancement (OAE). The resulting model code will then quantify the viability of gypsum precipitation from seawater as a safe, effective mCDR technology for the future.
C-BRINES brings together an international, interdisciplinary, intersectoral network spanning geoscience, oceanography, biogeochemistry, modelling, subsurface engineering, marine ecology, and environmental monitoring. Each DC will follow a personalised training pathway, enriched by secondments across academia, industry, and applied research organisations. Non-academic partners in gypsum production, OAE start-ups, marine ecosystem monitoring, ocean-clean-up technologies, gas storage, subsurface instrumentation, and biostratigraphy will contribute cutting-edge technology, data, and expertise, complementing the world-leading research facilities available through C-BRINES academic partners.
By combining frontier research, high-quality training and strong industry engagement, C-BRINES supports critical research aligned with Europe’s 2050 net zero target, while creating a new talent pipeline for the rapidly expanding mCDR. The project delivers both scientific innovation and the skilled workforce needed to scale-up next-generation negative-emission solutions in Europe and beyond.

Fields of science (EuroSciVoc)

CORDIS classifies projects with EuroSciVoc, a multilingual taxonomy of fields of science, through a semi-automatic process based on NLP techniques. See: The European Science Vocabulary.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
