| Research Abstract |
We have investigated temporal development of Emiliania huxleyi bloom on the continental shelf in the Bering Sea by a biomarker of E.huxleyi, C_<37> alkenones flux recorded in the sediments. As a result, the bloom had already been prominent since the middle of 1970's. We also found the E.huxleyi bloom would be promoted by active Aleutian low, positive anomaly of Pacific decadal oscillation and lowering of salinity.
