Vigorous deep-sea currents cause global anomaly in sediment accumulation in the Southern Ocean

Dutkiewicz, Adriana; Müller, R. Dietmar; Hogg, Andrew McC.; Spence, Paul


The vigorous current systems in the Southern Ocean play a key role in regulating the Earth’s oceans and climate, with the record of long-term environmental change mostly contained in deep-sea sediments. However, the well-established occurrence of widespread regional disconformities in the abyssal plains of the Southern Ocean attests to extensive erosion of deep-sea sediments during the Quaternary. We show that a wide belt of rapid sedimentation rates (>5.5 cm/k.y.) along the Southeast...[Show more]
