Objective

The main aim in the fourth laboratory is understand the ocean carbon cycle and its related biogeochemical environment. We wish to contribute to understanding the actual state of seasonal variability and comprehensive analysis of long-term variability in the biogeochemical cycles by making use of observations and models.
