Fossil Evidence of Reduced Nitrogen Fixation in Warm Oceans 3 Million Years Ago

Just now September 18, 2026 1 min read 📰 Phys.org

📋 Key Takeaway

The article discusses how fossil plankton shells indicate a reduction in nitrogen fixation in warmer oceans 3 million years ago, highlighting the importance of nitrogen in marine ecosystems. This research is relevant for understanding historical climate impacts, which could inform current environmental policies in Iran. Understanding these processes is crucial for Iran's marine biodiversity and fisheries.

Nitrogen is a key nutrient because it fuels the growth of plankton, which forms the basis of the marine food web. Two opposing processes determine the global nitrogen cycle: nitrogen fixation and denitrification.
