  1. Using Bluelink to study the upper ocean circulation of the southeast Indian Ocean Elizabeth Millar Tian Lei Dr Nicole Jones Prof. Gregory Ivey School of Environmental Systems Engineering

  2. Schematic diagrams showing origin of Leeuwin Current Domingues et al (2007) Simulated Lagrangian pathways between the Leeuwin Current System and the upper-ocean circulation of the southeast Indian Ocean, DSR II, 54: 797–817 Nof et al (2002) ‘‘Teddies’’ and the Origin of the Leeuwin Current, JPO, 32: 2571-88

  9. Dampier transectShelf break flow Typical flow; poleward, core at 200m isobath, max depth 300m Reversal: weaker, equator-ward

  10. Dampier transectTemporal variability Discharge at shelf break 2006 Discharge at shelf break 1997

  11. Conclusion

  12. Another Bluelink experience “We currently have the Salvage vessel "WAMBIRI" towing the fire stricken vessel "MSC LUGANO" from 200nm south of Esperance to Fremantle it appears as though they are are stuck doing 1.5 knots due to being caught in the Leeuwin Current. Do you have any way of tracking the currents via satellite so I can advise them which way to head best to avoid the said current?” Wed, 9 Apr 2008 Ports Manager WA Regional Ports SVITZER Australasia
