Open ocean productivity is widely constrained by the availability of key macronutrients and micronutrients, establishing nutrient limitation as a fundamental driver of marine biological activity.

The analysis

Both papers support the claim that open ocean regions experience limitations in photosynthetic productivity linked to nutrient availability, specifically highlighting macronutrient and iron constraints.

Balance between resource supply and demand determines nutrient limitation of primary productivity in the ocean

Recorded source metadata

George I. Hagstrom, Simon A. Levin, Adam C. Martiny. Balance between resource supply and demand determines nutrient limitation of primary productivity in the ocean. 2016. https://doi.org/10.1101/064543

Demonstrates that nutrient availability, such as nitrogen, phosphorus, and iron, ultimately determines primary productivity across different ocean regions.
