Satellite observations of unprecedented phytoplankton blooms in the Maud Rise polynya, Southern Ocean
The appearance of phytoplankton blooms within sea ice cover is of high importance considering the upper ocean primary production that controls the biological pump, with implications for atmospheric CO2 and global climate. Satellite-derived chlorophyll a concentration showed unprecedented phytoplankt...

The appearance of phytoplankton blooms within sea ice cover is of high importance considering the upper ocean primary production that controls the biological pump, with implications for atmospheric CO2 and global climate.

Multi-satellite data indicated that the bloom appeared for the first time since the entire mission records started in 1978.
