Deep ocean sensors, called gliders, have revealed new information about the journey of water from the Bass Strait to the Tasman sea and beyond.

Scientists from UTS and CSIRO were able to track a warm-core eddy – a 200-metre tall, 40 kilometre wide disc of water – as it traveled from the Bass Stait into the Tasman sea. It is possible for the water to make its way into the Indian Ocean as well.

Water from the Bass Strait has a unique chemical signature and scientists have found discs of water from the Bass strait that are undiluted, even after travelling hundreds of kilometres.

The warm-core eddies influence the temperature of the ocean and the food chain.
