It's the most obvious thing about salt water, but it's really important Out of the Blue

Salt. It's one of the things that makes seawater, well, seawater. In this episode, we chat to Dr Neil Malan from the University of New South Wales about why this mineral is so important in the oceans, shaping the way water moves and where ocean animals and plants live (did you know seabirds get their freshwater from the surface of the ocean after it rains?). Neil's recent research looks at how the huge floods on Australia's east coast had a big impact on the marine environment.Photo by Pavel Neznanov on Unsplash
