Editing Houtman Abrolhos (section)

===Currents===
The Houtman Abrolhos lies almost directly in the path of the [[Leeuwin Current]], which draws warm, low-saline water of tropical origin southwards along the coast of Western Australia. This current flows all year round, but is strongest during [[southern hemisphere]] winter months. In general the Leeuwin Current runs along the shelf break, and thus passes close by the western edge of the Abrolhos. It meanders, sometimes passing well out to sea and sometimes directly through the island chain, bathing it in warm tropical water;<ref name="Pearce 1997"/> Although the direction of the Leeuwin Current is predominantly southerly, [[Shark Bay, Western Australia|Shark Bay]] and the Houtman Abrolhos together act as a [[topography|topographical]] trigger for the forming of [[eddy (fluid dynamics)|eddies]],<ref name="Waite 2007">{{cite journal | first1 = A.

Unlike most other major ocean currents, there is no large-scale [[coastal upwelling]] associated with the Leeuwin Current. There is limited evidence for some sporadic, localised upwelling in the vicinity of the Abrolhos, but if so it appears to have little effect on the extremely low levels of nutrients in the water.<ref name="Pearce 1997"/>
