Wissenschaftliches Interesse

Dr. Mark Schmidt is member of the Marine Biogeochemistry Division of the German research institute GEOMAR and Associate Professor at University Kiel (“Privatdozent”). He started his scientific career in the 90th as a physical chemist (PhD in atmospheric chemistry), and then changed to earth sciences  (habilitation in geosciences in 2006). Over the last decades his research interest covered a wide range of using stable isotopes to reconstruct biogeochemical processes in earth sciences. He is specialized on mineral formation at cold and hot marine vent areas. Moreover, he investigated trace gas-formation, -degradation, and -transport processes in most of the oceans worldwide. Mark Schmidt participated on more than 50 international research cruises including offshore ROV, AUV, CTD, and Lander operations.
Actually a more applied and industry-related research is in focus (i.e. gas sensor development, under-water mass spectrometry, wave glider applications). In addition to research activities he is leading the gas chromatography and isotope ratio-mass spectrometry group in his department.
