Excess nitrogen as a marker of intense dinitrogen fixation in the Western Tropical South Pacific Ocean: impact on the thermocline waters of the South Pacific

“…The last part flows eastward along the Tasman Front (TF) (40°-45° S) through the north of New Zealand to become East Auckland Current (EAUC). It then joins back into and the circulation of the anticyclonic gyre through the South Pacific Current (SPC) which mostly circulates nearby the latitude of 30° S (Stramma et al, 1995;Talley et al, 2011). The CTD profiles collected during the OUTPACE cruise take 210 place in the southwestern Pacific region when the SEC encounters the Fiji and New Caledonia ( Fig, 2a; 2b).…”

“…2b). The South Equatorial Current (SEC) represents the northern branch of the southern subtropical anticyclonic gyre from the eastern boundary Peru-Chile Current (PCC) to the Coral Sea and the southwestern Pacific (Wyrtki, 1975;Solokov and Rintoul, 2000;Talley et al, 2011;Kessler and Cravatte, 2013). At depth, the SEC transports thermocline waters which are salty (larger than 35), and thus makes it possible to spatially couple the ETSP and the WTSP.…”
