Ocean Eddy

Event Chains

Ocean eddies drive complex event chains within a global system through distinct events in time and space. To assess how small-scale ocean processes interact with the large-scale ocean circulation, the following hypotheses shall be addressed by MOSES event-driven field campaigns:

(1) Mesoscale and submesoscale eddies play an important role in transferring energy along the energy cascade from the large-scale circulation to dissipation at the molecular level.

(2) Mesoscale and submesoscale eddies are an important driver in determining onset, magnitude and characteristics of primary production in the ocean and contribute significantly to global primary production.

(3) Mesoscale and submesoscale eddies are important for shaping extreme biogeochemical environments (e.g. pH, oxygen) in the oceans, thus acting as a source/sink function for greenhouse gases.
