•Meanders: Jet stream develop large oscillations caused by its unstable. •Rings: Eddy pinched off from meander as it become too large. Anticlockwise and clockwise rotating rings are cold and warm rings, respectively. They contain water from the opposite side of the stream having the other side’s physical, chemical and biological properties. The interaction of meander and rings create significant vertical transports of nutrient and plankton which enhance biological activity
