Short summary
The Ross Sea record of the Miocene Climatic Optimum (~16.9–14.7 Ma) and the Middle Miocene Climate Transition (~14.7–13.8 Ma) can provide critical insights into the Antarctic ocean–cryosphere system during an ancient time of extreme warmth and subsequent cooling. Benthic foraminifera inform us about water masses, currents, and glacial conditions in the Ross Sea, and planktic foram invaders can inform us of when warm waters melted the Antarctic Ice Sheet in the past.
