We present the first \r\n117-year long annually resolved marine climate history from the \r\nwestern Bering Sea/Aleutian Island region using information contained \r\nin the calcitic skeleton of the long-lived crustose coralline red alga \r\nClathromorphum nereostratum, a previously unused climate archive. \r\nThe skeletal d18O-time series indicates significant warming and/or \r\nfreshening of surface waters after the middle of the 20th century. \r\nFurthermore, the time series is spatiotemporally correlated with \r\nPacific Decadal Oscillation (PDO) and tropical El Niño-Southern \r\nOscillation (ENSO) indices. Even though the western Bering Sea/\r\nAleutian Island region is believed to be outside the area of \r\nsignificant marine response to ENSO, we propose that an ENSO signal \r\nis transmitted via the Alaskan Stream from the Eastern North Pacific, \r\na region of known ENSO teleconnections. \r\n","author":null,"citation":"Halfar, J., R.
