Marcus Klaus

I am a physical geographer whose research focuses on aquatic biogeochemistry, hydrology, and hydrodynamics. My work explores carbon cycling and greenhouse gas exchange in lakes, streams, and groundwater across temperate to subarctic environments. A central aim of my research is to understand the mechanisms that govern gas exchange across scales, from microscopic processes to regional patterns, while also linking these insights to broader syntheses and modelling efforts. More recently, I have been particularly interested in the role of bubbles in air–water gas exchange and their contribution to aquatic greenhouse gas emissions.

Major research projects:

Microbubbles – hidden gateways for greenhouse gas emissions from inland waters? (Swedish Research Council VR, 2023-2026)
The role of groundwater in the carbon cycle: long-term sink or overlooked legacy? (Swedish Geological Survey SGU, 2022-2024)
Reducing forestry related greenhouse gas emissions from stream ecosystems by smarter riparian buffer zones (Skogssällskapet, 2019-2022)
