Ronny Baaske

Ronny Baaske is a Researcher in the Marine Geosystems unit within the Marine Biogeochemistry division at GEOMAR Helmholtz Centre for Ocean Research Kiel. His work focuses on paleoceanographic reconstructions of Southern Ocean climate dynamics and carbon cycle interactions.

His research interests center on paleoceanography and marine biogeochemistry, specifically investigating how the Southern Ocean regulated historical climate systems and atmospheric CO₂ levels during past warm periods. His work contributes to GEOMAR's research program Changing Earth – Sustaining our Future, particularly in ocean-climate interactions and carbon sink mechanisms.

Ronny Baaske's recent contributions include studies on Southern Ocean climate controls, as highlighted in GEOMAR's October 6, 2025 news feature Cooler warm periods: How the Southern Ocean controlled the climate and the CO₂ content of the atmosphere. His work integrates paleoclimate archives with biogeochemical modeling to understand carbon sequestration processes.

Ronny Baaske is affiliated with GEOMAR's research infrastructure including the Ocean Science Centre Mindelo and Boknis Eck Time Series Station, supporting fieldwork in Atlantic Ocean carbon cycle studies.
