Jannik Martens

I am an earth and environmental scientist with interests in climate change and carbon cycling. My experience and area of expertise include marine geology, paleoclimate research, isotope geochemistry and molecular analysis of organic matter.

Fields of Interest

My scientific interests are in the field of global carbon cycling, climate-carbon couplings and paleoceanography, with specific focus on the Arctic region.
