Gaute Lavik

Gaute Lavik is a Researcher in the Department of Biogeochemistry at the Max Planck Institute for Marine Microbiology, Bremen. His work focuses on marine nitrogen and sulfur cycling, nutrient dynamics in oceanic oxygen minimum zones, and microbial mediation of global biogeochemical cycles. He employs stable isotope techniques, high-resolution chemical analysis, and in situ experiments to study processes such as denitrification, anammox, and methane formation in marine sediments and water columns.

Key research areas include understanding how microbial communities regulate nitrogen loss in coastal and open ocean environments, the role of sulfide in driving biogeochemical reactions, and the impact of environmental variables like light and freshwater discharge on biogeochemical processes. His studies often integrate field observations with laboratory incubations and isotopic tracing methodologies.

Publications highlight contributions to unraveling nitrogen cycling in the Arabian Sea, Peruvian oxygen minimum zones, and sub-Arctic fjords. Ongoing work addresses methane emissions from seagrass ecosystems and the influence of microbial metabolisms on carbon sequestration in oligotrophic regions.
