Short Wave The Great Antarctic Food Web Puzzle
Mar 10, 2025
Martina Messione is a biologist specializing in phytoplankton in Antarctic fjords and a key player in the FjordPhyto community science project. In this discussion, she highlights the critical role of phytoplankton as the backbone of the ocean's food web and how they are affected by melting glaciers and climate change. Excitingly, tourist-collected water samples contribute valuable data to help track these shifts. Martina emphasizes the importance of ongoing research to understand and protect these tiny yet powerful organisms in a rapidly changing environment.

Episode notes
Phytoplankton's Importance
- Phytoplankton, tiny drifting organisms, form the base of the ocean's food web, crucial for marine life and oxygen production.
- Antarctic polar fjords, rich in nutrients, support diverse phytoplankton communities vital for krill, which in turn sustain whales and other species.
Phytoplankton's Complexity
- Much remains unknown about phytoplankton, particularly in Antarctica, including their response to environmental changes and species diversity.
- Further genetic analysis reveals even greater complexity than previously understood.
Citizen Science in Antarctica
- The FjordPhyto project uses community science, with tourists collecting phytoplankton samples from Antarctic tour ships.
- This citizen science approach provides valuable data for researchers like Martina Messione.
