PMEL and Alaska Fisheries Science Center scientists have observed and sampled a large coccolithophore bloom, viewable even from space, in the Eastern Bering Sea during a recent October EcoFOCI research cruise.  This phytoplankton bloom is caused by the coccolithophore, Emiliania huxleyi, a one-celled marine algae with calcite plating, and has persisted for nearly three months, starting in July 2014.  Blooms of this size and duration have not been seen for over a decade in the Bering Sea. 

The satellite image from September 26 shows the aquamarine bloom with the white circles indicating sampling stations occupied by NOAA’s research vessel Oscar Dyson during the cruise.  For more information please visit the EcoFOCI cruise website.

Listen to PMEL's Greg Johnson on Science Friday. The world’s oceans are absorbing heat—but just how much they’re absorbing, and how quickly, are important questions for calculating the potential effects of a changing climate.

Earth’s oceans have absorbed more than 90% of the warming caused by greenhouse gases, researchers estimate, with the stored heat showing up as warmer seawater.
