Ship ballast dumps around Australia climbing increasing risk of invasive species getting foothold

(Phys.org)—A small team of math and biological researchers with the University of Adelaide, has found that the amount of ballast water being dumped into the waters around Australia more than doubled over a thirteen year study period increasing the possibly of invasive species introduction. In their paper published in Royal Society Open Science, the team describes how they studied historic ballast data to create a model of ballast dumping, and discovered that most of the increase can be attributed to mining operations.
