Australia’s marine environment is influenced by the cycles of several natural climate phenomena, including the El Niño–Southern Oscillation, the Indian Ocean Dipole and the Southern Annular Mode
2016 Key Finding2016 Variability in the phases of these climate phenomena change rainfall patterns, sea surface temperatures, surface winds and oceanic currents. These changes can influence the degree of vertical mixing through the water column and the relative location of cyclone events. Simultaneous...
