current

This in the POST...fine paper...two bucks to learn about the beautiful island? We would pay five, even.

Ocean currents bring tropical fish to Rottnest and oceanographer Alan Pearce will explain how at next week's meeting of the Naturalists' Club.

His talk at 7.30pm on June 11 is about ocean currents, tropical fish larvae and rock lobsters.

Alan trained as a mechanical engineer in South Africa before moving into oceanography, studying the ocean currents off Durban.

He joined the CSIRO in Sydney in 1977 and finally moved to Perth.

In his semi-retirement he has started a PhD study at Curtin University on ocean currents and larval fish.

His talk will be a mix of history, geography, oceanography and marine biology.

Knowledge of currents is closely linked to new technologies, including highly sophisticated and expensive current meters and drifters.

The society's meeting is at the Woolnough Lecture Theatre in the UWA Earth Sciences building, and is open to the public.

Entry is by $2 donation.
