Description

The largest ocean temperature gradients occur in the Southern Ocean, where the Antarctic circumpolar current frontal systems serve as hydrographic barriers with distinctive flora and fauna. During Pleistocene glacial-interglacial cycles, the position and intensity of these frontal systems are thought to have changed. This study examines the occurrence of distinct cryptic species of Orbulina universa during the Mid-Pleistocene Transition at two sites in the South Atlantic, Ocean Drilling Program...[Show more]
