The Leeuwin Current can be described as tropical current, consisting of warm, low salinity water that affects Western Australia's coastal waters and wildlife. Currents are a part of a large sub circular current system known as gyre. The currents in the Southern hemisphere gyres circulate in an anti-clockwise direction (Skinner, Porter & Botkin, 1999, p. 249). There is a current in all the major seas that generally flow northwards along the traditional western coast of continents. However , the Leeuwin Current runs southwards along the coast, before turning eastwards at Shawl Leeuwin and then into the Wonderful Australian Bight where their physical and chemical impacts reach as far as Tasmania (http://www.marine.csiro.au/Leafletsfolder/44leuwin/44.html). In this article some of these outcomes on the physico-chemical environment will be examined plus the possible reasons behind the Leeuwin Current will probably be looked at.

The Leeuwin Current has important consequences in both the local climate and ocean biota off of the coast of Western Sydney. The 1st part of this essay can study these kinds of effects and introduce the concept of low nutrition, low salinity and large water clearness. The Leeuwin Current originates from tropical locations, making it fairly warm besides the distinctive insufficient large-scale upwelling (http://www.per.marine.csiro.au/public/oceanography/regional/currents.html). Upwelling is the process by which subsurface waters stream upward and replace the water moving away (Skinner, et al, 1999). This process and other factors that cause the Leeuwin Current and its distinctive attributes will probably be analysed in later elements of this dissertation.


One of the most crucial influences that the Leeuwin Current has on ocean ecosystems is the water temperature. Continental shelf waters off the shoreline of European Australia couple of four deg warmer than any other continents of the identical latitude (http://www.per.marine.csiro.au/public/oceanography/regional/currents.html).
