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.
PMEL in the News
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.
Improved understanding of new potential Arctic-lower latitude weather linkages and implications for weather and climate predictions
The role of the Arctic in the global climate system is based on multiple processes unique to the Arctic, driven by modest global warming. Arctic temperatures continue to increase at least 3 times the rate of mid-latitude temperatures. Multiple feedbacks, such as clouds, loss of sea ice and snow cover, heat storage in the ocean, and atmospheric... more
