Abstract
This study reports a dense, late summer phytoplankton bloom in the Southern Ocean that accumulated unusually high levels of organic matter and supported feeding hot spots for birds and whales. The authors show that this recurring open ocean bloom is driven by anomalies in easterly winds that push sea ice southwards and favour the upwelling of deep waters enriched in hydrothermal iron.
