Brief description
Six free-drifting GPS-tracked buoys were released off Mandurah and Cape Naturaliste in November 2008 and March 2009. Two of these moved off the continental shelf, one northwards into the equatorial Indian Ocean and the other was entrained into the Leeuwin Current and was carried around to the south coast. The other four buoys drifted northwards along the continental shelf in the Capes Current, but showed some interesting current reversals and small-scale variability. These results are giving us a better idea of the likely movements of dhufish larvae (which spawn in this area in summer), both in terms of temporary retention in eddies/reversals and potential dispersal along the shelf.Lineage
Statement: Snapper samples (n = 857, 11 locations) from Shark Bay to SA border, dhufish (n=717, 9 locations) and baldchin (n=479, 7 locations)Notes
PurposeTo determine near-surface current trajectories along the Western Australian continental shelf in relation to larval transport.
