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…
Environmental predictors of deep-sea polymetallic nodule occurrence in the global ocean
Abstract: Polymetallic nodules found on the abyssal plains of the oceans represent one of the slowest known geological processes, and are a source of critical and rare metals for frontier technologies. A quantitative assessment of their occurrence worldwide has been hampered by a research focus on the northeastern Pacific Ocean and the lack of a … 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. …
