Eddy formation in the bays of Kamchatka and fluxes to the open ocean

The Eastern Kamchatka Current (EKC) is the western boundary current of North Pacific subpolar gyre. Southeast Peninsula lies a large anticyclonic eddy, Eddy (KE). This eddy quasi-stationary. More generally, oceanic region east EKC contains many eddies, several them and long lasting. Using surface currents derived from altimetry, particle tracking simple two-dimensional numerical model fluid flow, we investigate variability this field, generation eddies in bays by fluxes water to these bays. Firstly, recover our analysis long-lasting main region. Among strong parity bias favors anticyclones. Our simulations give possible explanation for process creation peninsula show that northernmost bay produces most Then, track forward particles determine their fate open ocean; southeastward southwestward trajectories are frequent. We also backward KE site; they often drift near coast, but others south site remain there, priori trapped other eddies. study confirms complexity mesoscale motions exchanges
