Welcome to the INSS


The International Nutrients Scale System (INSS) is an international collaborative programme with the aim of establishing global comparability and traceability of nutrient data in the world ocean.


In February 2009, the INSS group held a workshop at UNESCO in Paris to advance international collaboration in establishing global comparability of nutrient data in the world ocean and to discuss future tasks (2009 International Nutrients Scale System international workshop, Paris, 10–12 February 2009). An “International Nutrients Scale System (INSS)” in seawater was agreed as the appropriate way to achieve this goal.
