Marika Stock

PhD Candidate

Research Interests

I am interested in using a combination of paleoclimate (ice cores), atmospheric chemistry and geological approaches to help understand current climate change and investigate the gaps in knowledge in this field.  My current work involves field measurements of natural geologic methane flux out of sedimentary basins.  This information should help resolve the current discrepancy between top-down (ice core measurements of pre-industrial atmosphere) and bottom-up (upscaled natural geologic methane measurements) estimates of natural geologic methane contributions to the atmosphere. My past research focused on nitrous oxide concentrations from ice cores from the Allan Hills in Antarctica.

PhD Candidate

Research Interests

I am interested in improving our understanding of how past climates are preserved in ice cores. In my free time I ride my bike and think about how nice it would be to have a cat.
