Brief description

The Western Australian Department of Fisheries has been monitoring the trajectories of a series of drifting buoy releases along the Western Australian continental shelf since 2008. The objective of the programme is to study the current system on the continental shelf in relation to the migration of fish and invertebrate larvae, particularly over the summer months when some key pelagic species are spawning and also when the early-stage larvae of the western rock lobster are being transported offshore. To date, most of the releases have been along the lower west coast.

Lineage

Statement: The drifters selected for this project are the WOCE Surface Velocity Program (SVP) Iridium drifters supplied by the Canadian company MetOcean Data Systems (see thumbnail). They consist of a surface float unit 38 cm diameter and weighing 20.5 kg (this contains the electronics package, including a GPS transmitter, and batteries) and a "holey sock" drogue 6.44 m long and 60 cm diameter, suspended between 12 m and 18 m below the surface float. A sea surface temperature (SST) sensor is mounted near the base of the float to monitor the water temperature some 20 cm below the surface. In the early drifters, a conductivity "submergence" sensor near the top of the float is used to detect the proportion of the time that the float is awash as an indication that the drogue is still attached (the float is intermittently partially submerged as waves pass by). On the later units, a strain-meter is incorporated into the design to measure submergence based on the weight and drag of the drogue. The surface temperatures are relayed hourly and the drifter positions either hourly or 3-hourly (as pre-selected) to MetOcean Data Systems via the Iridium satellite system, and are downloaded from their website on demand.
