Scientists from around the globe are meeting in Nelson next week to discuss the latest advances in fisheries technology.

Unique research records rare whale species in Cook Strait

The sounds of whales and dolphins rarely seen in New Zealand waters have been recorded by NIWA scientist in a pioneering underwater sound project. In 2016 NIWA marine ecologist Dr Kim Goetz led a programme to deploy seven acoustic moorings in Cook Strait that recorded the sounds of marine mammals for six months until they were retrieved in December.
