Response of surface nutrient inventories and nitrogen fixation to a tropical cyclone in the southwest Pacific

Law, Cliff S; Woodward, E.M.S.; Ellwood, Michael; Marriner, A; Bury, S J; Safi, Karl A


To examine the controls of new nitrogen supply in oligotrophic waters, nitrogen fixation and nutrients were monitored during a quasi-Lagrangian study in surface waters of the north Tasman Sea during March-April 2006. The study was initiated coincident with a tropical cyclone, with high rainfall and winds that eroded surface layer density structure and increased surface phosphate and silicate concentrations by 50%. However, there was no corresponding increase in nitrate, as the enhanced vertical...[Show more]
