Miriam Seifert

Dr. Miriam Seifert is a Postdoctoral Researcher in Biogeochemical Modeling at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research. Her research focuses on understanding how marine ecosystems, particularly phytoplankton communities, respond to climate change and ocean acidification through advanced biogeochemical modeling approaches.

Her primary research interests include:

• Biogeochemical modelling of marine ecosystems
• Sensitivity of Phytoplankton to Climate Change
• Ocean alkalinization as a potential climate intervention strategy
• Interactions between multiple climate drivers in marine environments

Dr. Seifert's work demonstrates that phytoplankton responses to climate change cannot be predicted by examining single drivers in isolation. Her research shows that cascading effects through marine food webs significantly amplify the direct impacts of CO2 on phytoplankton growth. She has conducted extensive meta-analyses revealing how multiple environmental stressors interact in complex ways that fundamentally alter ecosystem responses to climate change.

Her scientific contributions span Arctic research, particularly examining carbon cycling in Greenland's Scoresby Sund fjord system and the impacts of glacial meltwater on marine biogeochemistry. She actively engages in science communication through the "Wissenschaft fürs Wohnzimmer" initiative, providing weekly interactive scientific livestreams to make complex climate science accessible to the public.
