Table 1 Simulated increase of integrated nitrate concentration upper 100 m by pass of cyclonic eddy with SSHA < − 50 cm (ΔintN(eddy)) and annual ΔintN(eddy)intAN(eddy)) between 2000 and 2012. ΔintAN(eddy) without winter cooling mixing period (WCM) data are also shown. “0” of S/N denotes that no eddy passed over KEO in respective years
