Truls Johannessen

Truls Johannessen is a Professor at the University of Bergen's Geophysical Institute and affiliated with the Bjerknes Centre for Climate Research. His work focuses on oceanography, biogeochemistry, and climate change, particularly in Arctic and subarctic regions. He has led initiatives like the ICOS Norway coordination (2008-2018) and contributed to international projects such as SOLAS and IMBER. Research emphasizes ocean acidification, CO₂ flux dynamics, and carbon cycle modeling. Key projects include the BCCR SFF (2002-2012) and ongoing contributions to INTAROS.

Research Interests: Climate variability, carbon sequestration, Arctic Ocean processes, and marine biogeochemical cycles. His work integrates observational data from platforms like Ocean Weather Station M with model-based approaches to understand long-term trends.

Articles Overview: Recent work addresses decadal acidification trends in the Norwegian Sea, Red Sea carbon dynamics, and Arctic CO₂ storage monitoring. Key themes include subpolar North Atlantic CO₂ sinks, anthropogenic carbon trends, and leakage detection strategies for carbon sequestration projects.

Grants & Projects: Coordinator for EU projects like INTAROS, participated in ESOP, CARBOOCEAN, and EURO-BASINS. Active in coordinating ICOS-Oceans and developing standardized CO₂ measurement networks.

Labs & Teams: Collaborates through the Bjerknes Centre's Climate Research Group and leads carbon cycle studies at the Geophysical Institute. Involves multi-disciplinary teams in oceanography, geochemistry, and climate modeling.
