An international collaboration between fishers and researchers recording ocean temperatures is expected to improve fishing and forecasting of significant weather events such as marine heatwaves, cyclones, La Niña or El Niño.

Sensors recording water temperature and depth have been attached to fishing gear on boats working across waters in New Zealand, Australia, the Southern Ocean and the Western Central Pacific.

More than 3 million recordings have been captured so far, creating a sub-surface temperature dataset that is giving new insight into what is happening beneath the ocean surface, a rarity in some of the world's most remote oceans.

Professor of oceanography at the University of New South Wales Moninya Roughan co-designed the sensors and is leading the Fisheries Ships of Opportunit
