Palynomorphs from a Sediment Core Reveal a Sudden Remarkably Warm Antarctica During the Middle Miocene

On the cover: The ANDRILL (ANtarctic geological DRILLing) Program’s drilling system successfully recovered more than 1100 meters of rock core (with >98% recovery) from a floating ice platform during the International Polar Year. Palynomorphs recovered from the AND-2A drillcore in McMurdo Sound, Antarctica, provide evidence for terrestrial vegetation and marine algal blooms, revealing a stage in Antarctica’s climate evolution during the Mid- Miocene Climatic Optimum.
