NOTION:
Nitrogen fixers structuring phytoplankton biodiversity in the ocean under climate change
- Duration:
- 15.04.2020 - 31.12.2025
- Project coordinated by:
- Mediterranean Institute of Oceanography (MIO)
- Project manager (IOW):
- Prof. Dr. Maren Voß
- Funding:

Focus 2: Basin-scale ecosystem dynamics
- Partner:
The goal of NOTION is to determine how climate change will affect the activity of diazotrophs, and how they will impact phytoplankton biodiversity and productivity in the future ocean. To that end, we will enhance global ocean ecological models with new datasets and parameterizations stemmed from dedicated experiments. NOTION will take the unprecedented challenge of integrating genetic data into biogeochemical models to cover an important current gap in our knowledge: bridging phylogenetic and functional diversity. This new insight will be highly useful for the scientific community, serving as a role model for future studies focusing on other planktonic groups.
