When organic particles sink from the surface ocean to the seafloor, a small but significant proportion of atmospheric carbon is stored away. Adriana Dutkiewicz and colleagues at the University of Sydney and Data61/CSIRO have now used global data sets collected over decades combined with cutting-edge big data analysis to understand how this process depends on surface ocean environments. … Read more…
How marine snow cools the planet
University of Sydney scientists have modelled how carbonate accumulation from ‘marine snow’ in oceans has absorbed carbon dioxide over millennia and been a key driver in keeping the planet cool for millions of years. Researchers in the School of Geosciences have mapped out how carbonate formations have helped regulate Earth’s temperature over 120 million years. … Read more…
Congratulations Adriana Dutkiewicz, Dietmar Müller, Andrew Hogg, and Paul Spence for their recent paper published in Geology. Their paper, Vigorous deep-sea currents cause global anomaly in sediment accumulation in the Southern Ocean, revealed an enormous stretch of the Southern Ocean where sediments are building up at a rate that dwarfs other deep ocean locations. The work has attracted the attention of media internationally. …

The recently-published ocean sediment map made by Dr Adriana Dutkiewicz and colleagues has taken the world’s media by storm. It’s been reported online and in press, from Australia to Cuba, Hungary and many other countries! See the updated list of media items below, and check out the link to the 
A team led by the University of Sydney School of Geosciences has created the first digital globe of seafloor sediments.
