Dr Daniel Harrison is an oceanographer and engineer at the National Marine Science Centre of Southern Cross University. Daniel’s research focuses on how human activities affect the oceans and the role the ocean can play in providing novel solutions to the global challenges posed by a rapidly changing climate. His research has covered the spectrum of estuarine microbiology and biogeochemistry, through global fisheries and aquaculture, to geoengineering and ocean-based carbon removal techniques. He was awarded a Myer Innovation Fellowship in 2017 to develop his concept of regional marine cloud brightening as a method for mitigating coral bleaching on the Great Barrier Reef. He also holds appointments at University of Sydney and the Sydney Institute of Marine Science.
