Karl Kaiser

Assistant Professor

Research Interests

1) Interactions between marine biogeochemical cycles, ocean chemistry and the climate system.

2) Linkages between terrestrial and marine C and N cycles
 (Application of plant and microbial biomarkers to examine transformations of POM and DOM)
3) Northern peatlands as major players in soil and atmospheric carbon cycling
 (Chemistry and decomposition of peat soils)
4) Dissolved organic matter compositions in groundwater

5) Biodegradation of contaminants in natural ecosystems
