Ионическое море
Which is a feedback mechanism between the Ionic and the Adriatic sea. The thermohaline properties of the Adriatic Sea show quasi-decadal oscillations that are related to the circulation of the Ionian Sea. The upper-layer of the northern Ionian Sea shows circulations that vary between a cyclonic movement, corresponding advection of waters from the Eastern Mediterranean with very saline waters and low nutrients (oligotrophic water), and anticyclonic movement which results in saline and copiotroph (nutrient rich) waters from the Western Mediterranean towards the Adriatic. The density of the dense waters that flow from the Adriatic Sea into the northern Ionian Sea highly depends on the type of circulation (cyclonic, or anticyclonic) in the Ionian Sea and at the other hand influences the vorticity in the Ionian Sea itself resulting in a feedback mechanism. BiOS is one of the dominant mechanisms influencing biochemical processes in the Adriatic and therefore has great impact on the organisms within this sea and in the strait.
