Sussing out sharks before they reach the shore

Summer swimmers and beach-goers in Australia always have sharks in the back of their mind, but what if there was a way we could detect them before they swim too close to shore?

A new technology has been trialled in Port Stephens, New South Wales called ‘Clever Buoy’ which uses sonar technology to trace out shark figures in the water and notify those of their presence back on shore.

But how can these technologies differentiate a shark from a seaweed cluster that might closely resemble a shark?
