Glacial sequence stratigraphy of ANDRILL ‐1B core reveals a dynamic subpolar Antarctic Ice Sheet in Ross Sea during the late Miocene

Abstract

The Upper Miocene interval of the AND-1B sediment core is a muddy ca 300 m thick succession of glacimarine strata that was recovered from the McMurdo sector of the Ross Ice Shelf, Antarctica. This succession comprises lithofacies consistent with those formed in modern polythermal glacial systems with large volumes of subglacial meltwater. In particular, meltwater-associated facies and iceberg-rafted debris suggest
