We observed two different regimes \r\nof climate variability in our record: a relatively dry/warm period \r\nbefore 900 cal yr BP (lower runoff and average SST 1°C warmer \r\nthan present day) and a wet/cold period after 750 cal yr BP \r\n(higher runoff and average SST 1°C colder than present day). \r\nRelatively colder SSTs were found during 750-600 and 450-250 \r\ncal yr BP, where the latter period roughly corresponds to the \r\ninterval defined for the Little Ice Age (LIA). Similar climatic \r\nswings have been observed previously in continental and marine \r\narchives of the last two millennia from central and southern Chile, \r\nsuggesting a strong latitudinal sensitivity to changes in the \r\nSouthern Westerly Winds, the main source of precipitation in \r\nsouthern Chile, and validating the regional nature of the LIA. \r\nOur results reveal the importance of the Chilean fjord system \r\nfor recording climate changes of regional and global significance.\r\n","author":null,"citation":"Sepúlveda, J., S.
