Since 1997, ocean color satellite images have revealed large-scale blooms of the coccolithophorid Emiliania huxleyi in the eastern Bering Sea. The blooms are often sustained over several months and have caused ecosystem changes in the Arctic Ocean, as well as in the Bering Sea. In this study scientists examined continental shelf sediment profiles of alkenone, a biomarker for E. huxleyi, covering the past ∼70 years. [Source: GLOBAL BIOGEOCHEMICAL CYCLES]
