To view the published open abstract, go to http://dx.doi.org/ 10.1029/2004GL021903.452We have generated a high-resolution record of alkenone sea surface temperature (SST) between 10–24 ka from Core MD01-2421 off central Japan, in the northwestern Pacific. The cooling by 5°C from 21 ka to 12.8 ka implies the equatorward shift of the subarctic boundary in the northwestern Pacific by ∼2.8° in latitude. This shift was a result of the stronger summer Okhotsk High. The Okhotsk High was likely enhanced by the combined effects of El Niño-like conditions in the tropical Pacific and the heating of the land surface of northeastern Siberia.American Geophysical Union2005-03-09engjournal articleAMhttp://hdl.handle.net/2115/28772https://doi.org/10.1029/2004GL0219030094-8276Geophysical Research Letters325L05609https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/28772/1/GRL32-5.pdfapplication/pdf265.91 KB2005-03-09
