In a first, a new study by researchers from the University of Sydney School of Life and Environmental Sciences and the Sydney Institute of Marine Science has quantified and mapped the extent of human development in oceans. Published in the Nature Sustainability journal on 31 August 2020, the study looks at the extent of how human construction everything from tunnels and bridges to infrastructure for energy extraction has modified the ocean. Dr Ana Bugnot, from the University of Sydney School of Life and Environmental Sciences, led this study and said that while ocean development is “nothing new", it has rapidly changed in recent times.
