CDRmare Structure

The DAM research mission CDRmare »Marine Carbon Sinks in Decarbonisation Pathways« investigates different methods of marine CO₂ removal and storage (alkalinisation, blue carbon, artificial upwelling, CCS) in terms of their potential, risks and trade-offs bringing them together in a transdisciplinary assessment framework. Research on artificial upwelling as a potential CDR method will be completed by the end of 2024. With the second funding phase that started in August 2024, the remaining CDR methods as well as the development of the assessment framework take place in five large research consortia within CDRmare.

Since the start of the second funding phase, the research mission has been coordinated by three co-chairs: Prof. Andreas Oschlies (GEOMAR), Dr. Nadine Mengis (GEOMAR) and Prof. Alexander Proelß (University of Hamburg). In funding phase 1 (2021-2024) CDRmare was led by Prof. Andreas Oschlies (GEOMAR) and Prof. Gregor Rehder (IOW).

Overview of the six consortia:
